💬 Security & Signing

Anticimex

@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! :beers:

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?

Anticimex

@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).

Damian

@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_SIGNATURES

the 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.

Anticimex

@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.

Damian

@anticimex
Should I look rather in gw logs or node's? Or both?

Anticimex

@damian I'd start with the nodes. I suspect it is at that end something is overwritten after the message is received and verified.

Damian

@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:

I looked via log 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?

Anticimex

@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.

Anticimex

@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.

Damian

@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.

Damian

@anticimex Thank you, I'll test it and let you know if it helped. PS. debug prints sent before was created in cito, this is my original script. But you find it well, it was instead of:

Serial.print("\nRelay State: ");
Serial.println(relayState[sensor]);

and

Serial.print("Relay state after if: ");
Serial.println(relayState[message.sensor]);

So basically the sections that you've mentioned as a possibly buggy.

Damian

@anticimex Yep, remodelling receive() function by adding variables and assigning values respectively message.sensor and message.getBool at the beginning got the job done. Now it works like a charm. Moreover, the whitelisting feature also works now - I had to do something wrong previously. Thank you once again for your help.

Anticimex

@damian great to hear! Happy secure home automating :)

This page is not up to date, and this is causing some confusion:
https://github.com/tsathishkumar/MySController-rs/issues/15

Anticimex

@alowhum but that is not part of the core library, right? So this thread is perhaps not the best place for discussing 3rd party tools.

alowhum

"This thread contains comments for the article "Security & Signing" posted on MySensors.org."

@Anticimex This thread is the thread attached to a page on MySensors.org about security.

I pointed to that (awesome) tool on Github as an example that the page has caused some confusion about whether or not MySensors supports encryption.

Anticimex

@alowhum ok, thanks. Well we do. So please notify that author.

Anticimex

@alowhum as for the link back to mysensors documentation, that documentation is about message signing which is not to be confused with encryption. And on the top of the article is links to the latest documentation which should reflect the latest status on both signing and encryption.
