💬 Security & Signing
-
@bilbolodz hm, no. I have not tested on a 8-lead device. Should not be a difference but I can neither deny nor confirm. My best suggestion would be to have a look with an oscilloscope on the wire to confirm that the signal quality is good.
-
Is SIGNING a RFM69_ENABLE_ENCRYPTION replacement? If so is it a better or worse solution? Maybe RFM69_ENABLE_ENCRYPTION is enough?
-
@melwinek encryption and signing have very different purpose.
Signing prevents other people from sending messages to control your nodes. Without signing, anyone with the right skill or software can take control of your nodes.
Encryption tries to hide the contents of the messages between your nodes. That does not prevent people from taking control of your nodes.
-
@melwinek signing and encryption are two completely different things. And they can be enabled at the same time if so desired. Signing provides authentication and encryption provides obscurity.
-
@Anticimex, @mfalkvidd But with the use of encryption so easily no one will take control, must break the code.
So it is best to simultaneously encrypt (eg RFID tag serial number when opening the gate) and sign (eg gate open message)?
-
@melwinek what prevents anyone from copying your encrypted message and record it. And then later send the same thing?
Encryption provides obscurity. You need signing for authentication. Signed messages cannot be repeated because they are always unique. Encryption does not necessarily guarantee that.
-
@bilbolodz I am getting the same message with a Sensebender Micro. I configured it for soft-signing with LOCK_CONFIGURATION enabled. Now I wanted to switch to hardware based signing.
Any way to unlock a locked configuration?
-
@t3chie there is no configuration to lock for soft signing. Configuration locking only applies to atsha204a. And if locked it cannot be unlocked. And normally you shouldn't need to either as the default settings set are the one to use, and unless you have been very creative in hacking the personalizer that configured should work just fine.
-
@Anticimex I tested first with softsigning but shortly after this realized that with soft signing the Sensebender has not enough space for debug messages.
I rerun the personalizer to switch to hardware based signing and hit the "Failed to wake device. Response: E7" message.
Played around and found that#define MY_SIGNING_ATSHA204_PIN 17
instead of
#define MY_SIGNING_ATSHA204_PIN 4made the personalizer happy again. I am still fighting with getting signing to work. Setting #define MY_SIGNING_REQUEST_SIGNATURES and MY_SIGNING_GW_REQUEST_SIGNATURES_FROM_ALL did not get me going.
-
@t3chie I assume you have personalized nodes and gw with the same hmac key?
-
@t3chie also that you also defined the signing enabled flag on all participants (but I think you get a preprocessor error if you don't)
-
Is it possible to use the ATSHA204A along with the Rpi directly attached NRF24L01+ gateway? I can see how to attach the ATSHA to the nodes, but how to attach it to the pi?
Thank you.
-
@skywatch no, not to my knowledge. The atsha driver is Arduino specific. I would happily review a pull request that ports the bit banged driver for Linux though
-
@skywatch the use case for atsha204a backed signing on rPi is limited though. As it is used as I gw (I presume) it is considered "protected" and is less sensitive for key dumping.
-
Thank you for the quick response. Maybe i mis-understand this?
I have got 10 ATSHA chips that I would like to attach to arsuino nodes to use with a raspberry pi based gateway/controller combo. Do I therefore need to attach the ATSHA to the rpi, or could I still use the ATSHA hardware on the arduinos without an ATSHA attached to the rpi?
I had assumed that the atsha chip would be needed at both ends for signing to work. Maybe that's not how it works?
-
@skywatch no, the software port is fully compatible with the atsha204a. So you can use Arduino nodes with atsha204a and they will work just fine with your rPi with software signing. Just as long as they all use the same hmac key.
-
I'm hoping that I did done all ok.
I've personalized the Arduino that acts as Gateway (connected via USB to a Raspberry PI) and I've personalized first node (a DHT22).
Both with software signature.This is the cat from Raspberry / Gateway Arduino:

PS I did delete some chars from the HMAC, nonces, etc etc
-
@sineverba the best way to determine that is to see if the messages you send arrive
if you enable signing and require signatures, unsigned or incorrectly signed messages will be rejected.
I see no errors in the log so it seems it works. The logs however don't match up. The hmac:s in one log does not match the hmac:s in the other.
-
@Anticimex
I can assure you that messages, nonces, hmacs and signatures are exactly the same in console gateway and in console of arduino mini.
I did delete some chars before posting for.... security (?)
Thank you for your answer!
-
@sineverba why did you delete them? There is nothing secret about them. They are sent over your radio link so they are to be considered very public, or signing wouldn't be useful, would it?
-
@Anticimex
I understand
The last thing: what's the sense of this message:Skipping security for command 3 type 17?
Thank you!
-
@sineverba it means that message is not signed. Because it is of a type not suitable for signing. Typically an ack or a handshake message. You can look the type up in the api specification. In this case it is a handshake message (a nonce reply to be precise).
-
Hello!! I'm also trying to implement SOFT Signature, but because of my poor English I have many problems !!
Someone could post the socket of a node + a working MQTT gateway.So you can study the code and understand how it works !!!
Thanks 1000 in advance to who can help me
-
@sindrome73 There is no difference for a MQTT gw than from other GW:s. There are code examples in the documentation. See this post and follow the Doxygen links.
-
As I said, my English is not good and therefore it is difficult for me to follow the discussions.
That's why I was asking for a snapshot already done, in order to study the code and understand how to solve ....
If anyone can help me ????
-
@sindrome73 I am afraid it will be difficult to help if you can't read the code. There is code in the documentation, and you ask for code? There is also a sequence of steps required to do personalization, so you have to be able to understand english to some extent, or find someone who can translate for you.
If it helps, I have pasted the code here in case you for some reason can't find it (I assume you use a official 2.0 release):
How to use this
Before we begin with the details, I just want to emphasize that signing is completely optional and not enabled by default. If you do want the additional security layer signing provides, you pick the backend of your choise in your sketch. Currently, two compatible backends are supported; MY_SIGNING_ATSHA204 (hardware backed) and MY_SIGNING_SOFT (software backed). You can either enable these globally in MyConfig.h or in your sketch for sketch specific/local use.
Firstly, you need to make sure to pick a backend to use as described above.
//#define MY_SIGNING_SOFT #define MY_SIGNING_ATSHA204 #include <MySensors.h> ...Make sure to set the define before the inclusion of MySensors.h. It is legal to mix hardware- and software-based backends in a network. They work together.
You also need to decide if the node (or gateway) in question require and verify signatures in addition to calculating them. This has to be set by at least one of the node in a "pair" or nobody will actually start calculating a signature for a message. Just set the flag MY_SIGNING_REQUEST_SIGNATURES and the node will inform the gateway that it expects the gateway to sign all messages sent to the node. If this is set in a gateway, it will NOT force all nodes to sign messages to it. It will only require signatures from nodes that in turn require signatures. If it is desired that the gateway should require signatures from all nodes, MY_SIGNING_GW_REQUEST_SIGNATURES_FROM_ALL can be set in the gateway sketch.
If you want to have two nodes communicate securely directly with each other, the nodes that require signatures must send a presentation message to all nodes it expect signed messages from (only the gateway is informed automatically). See signerPresentation().
A node can have three "states" with respect to signing:Node does not support signing in any way (neither MY_SIGNING_ATSHA204 nor MY_SIGNING_SOFT is set)
Node does support signing but don't require messages sent to it to be signed (MY_SIGNING_REQUEST_SIGNATURES is not set)
Node does support signing and require messages sent to it to be signed (MY_SIGNING_REQUEST_SIGNATURES is set)Secondly, you need to verify the configuration for the backend.
For hardware backed signing it is the pin the device is connected to. In MyConfig.h there are defaults which you might need to adjust to match your personal build. The setting is defined using MY_SIGNING_ATSHA204_PIN and the default is to use pin A3.
Similar to picking your backend, this can also be set in your sketch:#define MY_SIGNING_ATSHA204 #define MY_SIGNING_ATSHA204_PIN 4 #define MY_SIGNING_REQUEST_SIGNATURES #include <MySensors.h> ...For the software backed signingbackend, an unconnected analog pin is required to set a random seed for the pseudo-random generator. It is important that the pin is floating, or the output of the pseudo-random generator will be predictable, and thus compromise the signatures. The setting is defined using MY_SIGNING_SOFT_RANDOMSEED_PIN and the default is to use pin A7. The same configuration possibilities exist as with the other configuration options.
Thirdly, if you use the software backend, you need to personalize the node (see personalization).
#define MY_SIGNING_SOFT #define MY_SIGNING_SOFT_RANDOMSEED_PIN 7 #define MY_SIGNING_REQUEST_SIGNATURES #include <MySensors.h> ...An example of a node that require signatures is available in SecureActuator.ino.
-
#define MY_SIGNING_SOFT_RANDOMSEED_PIN 7I image not, but... the pin need to be to same in every node?
And.. will the library auto manage the PIN (in this case the #7) rendering it floating or need to explicity set it as INPUT on sketch?
Thank you!
-
@sineverba It is assumed that you do any configurations in your sketch, before including MySensors.h so no, it does not need to be the same on every node. It just need to be left unconnected. And yes, the library takes care of the rest.
-
The pin does not need to be the same.
The library will set it to the required mode, there is no need to do anything in the sketch.
-
Hi
I have a gateway mysensors on my RPI3 with radio RFM69HW. Is any chance to build gateway on RPI3 but also with chip ATSHA204A ? And how build it...
-
@pepson the driver has not been designed with rPi in mind. And you'd probably be better off with an I2C variant for rPi. But we currently don't offer a driver for that so you'd have to write it yourself.
But, for a gw, you typically keep those secured physically, so using a atsha device is less important, compared to "roaming" nodes.
-
@anticimex
I don't understand. I want secure my nodes... By Atsha204a. How I can secure it by other solution.
-
@pepson I have implemented a sw emulator for the atsha which offers compatible security infrastructure but without readout protection. Readout protection is needed if someone steals your node and extracts your hmac key. Your gw won't typically be stolen, so it don't need readout protection and can rely on the soft signing option which is compatible with nodes using atsha204a personalized with the same hmac key. The rPi port support the atsha204a emulator so you can use that to secure nodes that has a real atsha204a device.
-
Can you show me full manual how implement it on Gateway on RPI and how add this to sketch on nodes ? Please...
If you can describe me very good. I am begginer...
-
@pepson you have the links to the documentation in the article this thread is commenting on. At the very top.
-
@anticimex
But please show me as you have to have example...
-
@pepson I don't run on raspberry pi so I don't. But the documentation does have specific configuration examples for raspberry pi, so you have all information needed listed there in "how to use this" section.
-
@pepson see here for 2.2.0 and on left menu for 2.3.0
https://github.com/sineverba/domapi/wiki/MySensors-2.2.0-Security-and-signin
-
@sineverba
Very very good manuals...
But i dont understand what i must type number in this placeand how get it ? It is MAC number network from RPI ?:#define MY_SIGNING_NODE_WHITELISTING {{.nodeId = GATEWAY_ADDRESS,.serial = {0Xaa,0Xbb,0Xcc,0XF9,0X82,0XB2,0X50,0XF2,0XAB}}} // got from gateway setup
And what is diffrent with MySensors 2.3.0 ?
I must do all point from MySensors 2.2.0 and additional point for 2.3.0 ?After got your ./configure instruction, type
sudo nano /etc/mysensors.conf
And add your KEYs to the specific section on bottom of the file.
To get your first KEYs follow guide for 2.2.0And in version 2.3.0 i must do this under building gateway ?
And add serial,HMAC,AES in this place in mysensors.conf
Software signing settings
Note: The gateway must have been built with signing
support to use the options below.
To generate a HMAC key run mysgw with: --gen-soft-hmac-key
copy the new key in the line below and uncomment it.
#soft_hmac_key=
To generate a serial key run mysgw with: --gen-soft-serial-key
copy the new key in the line below and uncomment it.
#soft_serial_key=
Encryption settings
Note: The gateway must have been built with encryption
support to use the options below.
To generate a AES key run mysgw with: --gen-aes-key
copy the new key in the line below and uncomment it.
#aes_key=
and then build gateway ?
-
@pepson You use RFM69(H/W/HW). So I. My hint is remain with 2.2.0. I got so many issues with 2.3.0 and RFM that I reverted to 2.2.0 in 1 minute.
HMAC is not LAN MAC, is HMAC got from MYsensors gateway. Same for other 2 keyes.
I think that in long explain on my guide you have all info to get your keyes. I follow my same guide everytime I need to reinstall mysensors / domoticz / an entire PI. It is fully tested
-
@sineverba
Hi
Yes i use radio RFM69HW. I also on 2.3.0 have big problem... and back to 2.2.0. What you have problem on 2.3.0 with radio RFM69 ?I read all your guide and it is ok. But i dont know what i must put in place:
#define MY_SIGNING_NODE_WHITELISTING {{.nodeId = GATEWAY_ADDRESS,.serial = {0Xaa,0Xbb,0Xcc,0XF9,0X82,0XB2,0X50,0XF2,0XAB}}} // got from gateway setupPut serial from this:
sudo mysgw --gen-soft-serial-keyWe will get:
SOFT_SERIAL | 7850987FA6601F6538
The next line is intended to be used in SecurityPersonalizer.ino:
#define MY_SOFT_SERIAL 0X78,0X50,0X98,0X7F,0XA6,0X60,0X1F,0X65,0X38To use this key, run mysgw with:
--set-soft-serial-key=7850987FA6601F6538And i must put my keys to mysensors.conf when i use version 2.2.0 ? Or only when use 2.3.0 ?
Software signing settings
Note: The gateway must have been built with signing
support to use the options below.
To generate a HMAC key run mysgw with: --gen-soft-hmac-key

-
Too many ack lost and slow communication. And other that I don't remember.
That line on the sketches means that you need add on the node that you want whitelist the serial of gateway.
You got serial gateway on the steps for 2.2.0.
You have it.
You don't need to put anything in no file with 2.2.0. In my guide is NOT mentioned. In my guide, at the bottom, there is the final "set keyes" with only a line OR you can set them everytime you get them.
Please, take your time to read 1, 2, 3 times before type anything. I think it is very clear, and every step is write down for you.
Enjoy PS Don't offend, I want help you, 'cause I used a bit of times before getting security working. And I used so many time write down a guide. But you need to read and follow carefully
-
@sineverba I also have the same problem with communication. But tell me you send issue to developer ? I send but nothing done.
Ok in point 4 in your guide in sketch for node i must put serial key from gateway ? Yes ?
And tell me how remove setup serial, HMAC and AES when i dont want to use it ? How remove it from gateway ?
Thanks
-
Any help ?
-
@pepson no need to remove. Simply, in your sketches, don't use signing at all.
-
@sineverba said in
Security & Signing:no need to remove. Simply, in your sketches, don't use signing at all.
ok but if on gateway it was generate and setup keys and when in skethces i dont use keys will nody connect? and what the purpose of the signature is then ?
I thought that if the gate has a set of keys and will try to connect noda without a key that it will not connect ....
-
@pepson you can use a special flag define to "downgrade/reduce" security MY_WEAK_SECURITY
-
Ok summary
When i have setup on Raspberry Gateway , generate keys.When i write in node all keys with sketches.... Node connect ok.
But when write to node only sketches without keys.,... node connect to gateway or not connect to gateway ?
-
@pepson you need to setup gateway with weak security.
You need generate keyes and set in gateway.
You need to personalize nodes with the sketch and set keyes on Arduino EEPROM.
From now, you have two ways: Your node need security? Set use security bla-bla on top with other define(s).
Don't Need security? Don't define use security.
Simpler than ever.
-
@pepson if you find the security setup to be too complicated, I highly recommend sticking with the simple password flags. The documentation has it all.
-
@sineverba said in
Security & Signing:setup gateway with weak security.
But when configure my gateway without flag setup gateway with weak security i can only use nodes with setup in sketches keys. yes ?
-
Can you share me this document when is describe how define only pass ? I want also read this.
-
Let's summarize. Last time.
- compile gateway with weak security (make your research, also in my github guide, there is )
- create the 3 keyes for gateway
- set the 3 keyes for gateway.
- clean your EEPROM arduinos with the sketch present in my guide and in examples of library
- set the keyes in EEPROM arduinos.
Stop. End. Fin. Fine. These steps are MANDATARY. You NEED to do.
You will have in EEPROM the keyes (arduino) and in gateway.
From now, you select:
a) Do I need security? Perfect, in sketch arduino add #define bla bla bla on top with security and other stuff.
b) Do I NOT need security? Perfect, in sketch arduino DON'T ADD #define bla bla related to security.
- compile gateway with weak security (make your research, also in my github guide, there is
-
@pepson And, last all, you can use the mysensors debug options. Try. Try. Try! This is the best option offered to you to learn. Try!
At max, nothing works
-
@sineverba
ok all is very good.But what give me this if i can connect nodes also with defines bla bla bla in skethc and also without define bla bla bla in sketch?
But Do I think right ? In each of these accidents in the eeprom I need to have the keys loaded?
-
@pepson only one word. Try. Really, you are lost in 1 cm of water. Try. And if it doesn't work, open your topic, showing exactly your sketches and what have you done.
-
ok thanks
-
Ok i build my gateway on RPI on MySensors 2.2.0 with this configuration:
./configure --my-transport=rfm69 --my-rfm69-frequency=868 --my-is-rfm69hw --my-gateway=ethernet --my-port=5003 --my-signing=software --my-signing-request-signatures
Then generate 3 key and setup it on gateway.
Then clear_epprom on Arduino MIni Pro, and then send sketch security with add serial, HMAC, and AES. Then put sketch with add this on top sketch with my SERIAL generated on gateway RPI.
#define MY_SIGNING_SOFT
#define MY_SIGNING_SOFT_RANDOMSEED_PIN 7
#define MY_SIGNING_REQUEST_SIGNATURES
#define MY_SIGNING_NODE_WHITELISTING {{.nodeId = GATEWAY_ADDRESS,.serial = {0X2C,0X61,0X17,0X2E,0XEE,0XDD,0XCC,0XBB,0XAA}}} // got from gateway setupAfter that i run HA and he not found my nodes...
WHat is wrondg ?
-
@pepson well for starters, don't start out with whitelisting unless you know exactly what you are doing. First you have to verify that your network is stable enough to handle the security protocol. The simplest option is to only enable encryption, or use the simple password flag options. Once you have established that your gw and nodes are capable of communicating securely you can move on to personalization and whitelisting.
-
@anticimex
What you mean white list?Before adding all security my nodes and gateway works perfect.
-
@pepson you define whitelisting so I presume you use it. But I don't see your gw flags specifying it so of course it does not work. So get rid of that flag from your config unless you know what it mean so that you set it up properly.
-
What flag i must remove ?

@pepson please just read the documentation. And more importantly, follow it.
Isn't it obvious that it is the flag that mention whitelisting that is supposed to be removed unless you intend to use whitelisting, in which case you ought to know how to set it up properly at both ends?

Sorry i dont undestand

Note that it is the documentation for the latest release (simple password flags work differently compared to previous releases, see release notes for the latest release).

- install gateway on raspberry with this configuration:
-
@pepson said in
Security & Signing:MY_SIGNING_NODE_WHITELISTING
How many times do I need to tell you to get rid of the whitelisting flag?
-
@anticimex
Ok read... but...
when i use MY_SIGNING_NODE_WHITELISTING i must on node in sketch add serial number my gateway and also serial number for node. But from where i can get serial number for my arduino pro mini ? I dont know...becasue i don use ATSHA204 but i use only soft signing....
-
@pepson This is the serial OF GATEWAY. Not your Arduino. You need to put serial of GATEWAY.
Please, first of all, DONT' USE WHITELISTING. And pay attention: if you enabled it, remove it and:
1 - clear eeprom
2 - flash eeprom with keyes
3 - reload sketch (without whitelisting)
-
@pepson Don't need all copy and paste, enough link :).
Btw, before move to Home Assistant, where is the output of debug of MySensors?
sudo mysgw -dOf course, you need before stop service.
Resetting the node, what you get in debug?
When ALL ok, move to HomeAssistant.
And remember, after check that debug is ok...
sudo make install && sudo systemctl enable mysgw.service && sudo systemctl start mysgw.service
-
In my first time I use only serial number gateway in flag whitelistening and also not working.
-
@pepson Last time. Please.
REMOVE
WHITELISTING
FROM
YOUR
SKETCHClear EEPROM and paste here output of debug. No other.
-
@sineverba
OK wait for info
-
Ok i removed Whitelisting and switch is show in Hoem Assistant and works.

@pepson your gw is configured to require signing from all nodes.
Your node 33 is set up to use signing. Your node 3 is not. Hence messages from node 3 will be rejected by the GW.
Either set up all nodes to use signing or set up weak security on the GW to only require signing from nodes that require it in turn.
This is documented behaviour. Please read the documentation. That is what it is for.
-
But still I don't know how use white listening...?
-
@pepson I suggest you avoid it. It require good tracking of all serials in your network and is part of the more advanced security mechanisms. And I suspect you will get issues when you add new nodes to your network as you cannot get it to work with just two nodes (you still have not enabled it on your gw). So just avoid whitelisting all together.
-
@anticimex
OK but how I can get serial from my Node on Arduino Pro Mini?And when I want use chip AtSHA204A what I must change on my GW and on Node?
Can I build GW on Rpi with this chip AtSHA204A?
-
@pepson Please. Read. The. Documentation.
And no, atsha204a is not supported on rPi. Nor does it need to be.
-
@anticimex
But still I don't know how read serial number from Node on Arduino Mini Pro when I want use White Listening...
-
@pepson have you read the documentation? Do you understand the concept of personalization? Where have you found information on from where the serial number is obtained?
I will only say this once more: don't use whitelisting unless you know these things. Serial is only used for whitelisting. Don't use something you do not understand.
All your questions so far can be answered by citing the documentation so please read it!
-
I have my network with NRF24+'s with HW signing. Now, due to performance limitations of the NRF's I'll move to RFM69's which supports encryption.
How can I set encryption in Mysensors? Is it already available? Can I have both signing and Encryption?
-
@joaoabs yes, it's all in the documentation
Let me know if you can't find it. Links are in the readme.md in git and in github.
-
Hi,
I've been a while on MySensors forum, most time as a reader. Read the docs about signing and have a couple of questions - possibly stupid as I might not understand well the docs.- I'd like to ask if the flags --my-signing-weak_security and --my-signing-request-signatures (yes I have RPi gw) are complementary or separate: if I define both, do I get a "weak security" feature or the "request security" is on top of that and only signed messages would be accepted? Or maybe I need to define one of them only depending on security level I want to achieve?
- Whitelisting - many things were said here, I am not planning to use it for now nor anytime for gateway on nodes as I do not find it necessary as gw is not supposed to be compromised, but did a quick test following the @sineverba tutorial and it failed indeed as pepson said. The serial which I provided in sketch in #define MY_SIGNING_NODE_WHITELISTING {{.nodeId = GATEWAY_ADDRESS,.serial = {myserial}}} was the one generated by mysgq --gen-soft-serial-key (and then applied by --set-soft-serial-key ofc) - is that correct? I also tried to replace GATEWAY_ADDRESS with 0 and no success. Maybe there are some other steps that I should take (@Anticimex said something like "But I don't see your gw flags specifying it" which I dont understand in this context)
- Is the encryption possible to be enabled only by compiling the gw with --my-rf24-encryption-enabled (for my nrf24) and personalizing gw and node with the same AES key obtained in this docs and by defining the proper flags in sketches on all nodes or is this procedure is more complicated? If this is not the subject for the scope of this thread please tell me I will search more.
Thank you for understanding my possibly dumb questions
I try my best but I am a beginner iot, but work in IT so not a total newbe in programming or technologies.
-
@damian There are no stupid questions on complex matters. Security is a complex matter (unfortunately).
-
The weak security flag allows a node to inform a GW that it no longer require signing. Thus, an attacker might "take over" a node and replace it with a non-secure one possibly without you noticing.
The request signature flag lets a node (or GW) informe a GW (or node) that it require signatures. That allows the other side to understand that it has to sign messages sent to the destination. It is therefore not to be confused with "weak security". It is more a "enable security". -
Writing #define MY_SIGNING_NODE_WHITELISTING {{.nodeId = GATEWAY_ADDRESS,.serial = {myserial}}} in a node, tells the node to requrie the GW to salt the signatures with it's serial (that should match the serial you entered in the node).
If the messages fail to verify, it suggests that the GW either has not realized it is expected to salt the signatures, or it uses the wrong serial to do it. Unfortunately I do not have a rPi setup to check this, so any help in troubleshooting that would be appreciated. -
Yes, just make sure to also enable encryption on the node. Also, do notice that ALL nodes on the same network needs to use encryption with the same key.
I hope this clarifies the things a bit
-
-
@anticimex thanks for the answer.
- I understand the idea. However, I think I might asked not clear enough. I would like to know how the mysgw daemon would work after the compilation depending on the flags I provide.
I understand that when I compile my gw with only --my-signing-request-signatures it will require all nodes in the network to sign messages. But if I want only some of them to sign messages and some not, do I have to compile the gw with both flags: --my-signing-request-signatures AND --my-signing-weak_security or only: --my-signing-weak_security ? - I think it might be an RPi issue, because the idea and setup seems to be correct. I'll try one day to test it in node-to-node communication or some test serial gw on Arduino. This is not so important to me as the signing itself works fine, just was curious.
- clear, hope it work. In the meantime I found: https://forum.mysensors.org/topic/2005/software-aes-encryption-for-nrf24 which looks worth testing as well. TL;DR carefully yet.
- I understand the idea. However, I think I might asked not clear enough. I would like to know how the mysgw daemon would work after the compilation depending on the flags I provide.
-
- You need to compile with --my-signing-request-signatures AND --my-signing-weak_security. See https://www.mysensors.org/apidocs/group__SigningSettingGrpPub.html#gaf44407e0f498eca7069adf5e59ffe052
- RF24 encryption is implemented in SW and currently available (with static IV). See https://www.mysensors.org/apidocs/group__EncryptionSettingGrpPub.html
-
@anticimex Thank you so much for clarification I owe you a beer
So another question for future considerations - is it possible to read eeprom to get the keys? I suppose the answer is yes as the whitelisting feature is introduced, but is it a hard task or keys could be fetched by a simple script reading eeprom?

@damian Reading EEPROM is quite trivial for a determined attacker, hence I discourage SW based security as it does not have the means of storing secrets securely on devices as the atmega328p.
HW based signing is available using the atsha204a in which case signing keys are protected. Encryption keys are not unfortunately as all encryption is currently SW based (or HW accelerated but still SW dependent).
"Security V3" will resolve this, but I unfortunately have no ETA.You are welcome!

I've just applied signing to my own written sketch and hit a wall. Basically the signing works fine - I get time from controller and it works fine - any signed time packets from controller are read. However I've got issues with my receive(const MyMessage &message) function. The function gets the state change for the relay from the controller and to determine which relay should be changed it uses message.sensor method. When the signing is turned off it returns 0 or 1 (for 2 relays). However, when the signing is enabled it returns always 255. Any ideas why?
-
@damian the only thing I can think of is that you don't read the part of the message you think you read. Could you please provide some logs where you print the message in its entirety? The signing backend also has flags for verbose debugging (see the flags in the docs).
-
@anticimex I will send logs, for now do not have access to hardware (I'm out of home). I am curious what could be the reason, as I said, I set all keys and the signing itself seems to work well. When I disable:
//#define MY_SIGNING_SOFT //#define MY_SIGNING_SOFT_RANDOMSEED_PIN 7 //#define MY_SIGNING_REQUEST_SIGNATURESthe sketch works fine. When they are enabled, I can see that the messages are received (I can see the change of the state of relay but I cannot read which relay should be change. Here's a part of my sketch, maybe there is a trivial mistake in it:
#define NUMBER_OF_RELAYS 2 #define R_CHILD_ID 0 #define RELAY_PIN 3 MyMessage msg[NUMBER_OF_RELAYS]; bool relayState[NUMBER_OF_RELAYS] = {false}; bool controllerState [NUMBER_OF_RELAYS] = {false}; void presentation() { for (int i=0, r_id=R_CHILD_ID; i<NUMBER_OF_RELAYS; i++, r_id++) { present(r_id, S_BINARY); msg[i] = MyMessage(r_id, V_STATUS); } } void receive(const MyMessage &message) { if (message.type==V_STATUS) { controllerState[message.sensor] = message.getBool(); if (controllerState[message.sensor] != relayState[message.sensor]) { relayState[message.sensor] = controllerState[message.sensor]; } Serial.print("Message Sensor id: "); Serial.println(message.sensor); digitalWrite(RELAY_PIN+message.sensor, relayState[message.sensor] ? RELAY_ON : RELAY_OFF); } }when I dump to console controllerState[message.sensor] value I can see it changes, no matter the fact that it points on the table out of the range as I check it later when read message.sensor value. So it leads me to conclusion that message.getBool(); works OK (now I think I should Serial.println(message.getBool()) to get straight the value and make sure it really works fine... I will test it), however:
Serial.print("Message Sensor id: "); Serial.println(message.sensor);gives me always the value of 255 instead of 0 or 1 in this case. Of course I gave here only the most important parts of my code which I think causes problems.
-
@damian It sure looks like message.sensor is cleared/reset for some reason. The verbose logs should show more details and hopefully reveal when in the call path, this happens.
-
@anticimex
Should I look rather in gw logs or node's? Or both?
-
@damian I'd start with the nodes. I suspect it is at that end something is overwritten after the message is received and verified.
-
@anticimex here are some logs from the node:
- Actions without signing - relay 0 on -> off -> relay 1 on -> off
message.getBool: 1 message.sensor: 0 message.getBool: 0 message.sensor: 0 message.getBool: 1 message.sensor: 1 message.getBool: 0 message.sensor: 1```- Actions with signing the same sequence as in the above:
message.getBool: 1 message.sensor: 255 message.getBool: 0 message.sensor: 255 message.getBool: 1 message.sensor: 255 message.getBool: 0 message.sensor: 255- Same as the 2nd but with debug logs from the node start:

parser and it is not looking bad for me. Do you find any suspicious behaviour here? I didn't mention - I use MySensors 2.2. Should I switch to 2.3?
-
@damian interesting. It would appear that verified messages has part of the header overwritten. I will take a closer look tomorrow. If you want, please test with the latest release, although there have not to my knowledge been made any changes relating to this issue.
If you want, please also add some debug printing on the sensor value of the message buffer as it is received and goes though the process of verification and propagates out of the internals in the library. I will look in the code to see if I can find an explanation for the corruption.
-
@damian Can you please share your sketch including your debug statements? It appears to me that your node between the print "message.getBool: 1" and "message.sensor: 255" is sending something to the GW. That initiates security handshaking so "message" will not be the same between the first and second print.

@anticimex Sure, here it is (still under development so there are some minor, I hope, bugs)

@damian Hm, I don't find your debug prints you used earlier.
But in general, I would say that the message object might be overwritten by the library, so if you need to use parts of it, make a copy of the parts you use first and then reference the copy to make sure a new incoming message does not overwrite it.
Eg, in receive():void receive(const MyMessage &message) { if (message.type==V_STATUS) { bool value = message.getBool(); uint8_t sensor = message.sensor; if (firstRun) { relayState[sensor] = value; } else { controllerState[sensor] = value; Serial.print("\nRelay State: "); Serial.println(relayState[sensor]); Serial.print("Switching to: "); Serial.println(controllerState[sensor]); if (controllerState[sensor] != relayState[sensor]) { relayState[sensor] = controllerState[sensor]; wait(waitDelay); send(msg[sensor].set(relayState[sensor]), false); } Serial.print("Relay state after if: "); Serial.println(relayState[sensor]); digitalWrite(RELAY_PIN+sensor, relayState[sensor] ? RELAY_ON : RELAY_OFF); } } }And I believe the cause for your problem is that you do
send(msg[message.sensor].set(relayState[message.sensor]), false);after
Serial.print("Switching to: "); Serial.println(controllerState[message.sensor]);but before
Serial.print("Relay state after if: "); Serial.println(relayState[message.sensor]);so message might be changed between since the send() will request a nonce from the GW which then overwrites the buffer referenced by
message.
