[Solved] Soft signing with whitelist on nodes

[carlierd]

Hello,

This is what I want to do:

• soft signing between a serial gateway and different nodes
• serial gateway accept data from any nodes (no whitelist on it)
• nodes only accept data from the serial gateway using whitelist

The code in the gateway:

uint8_t soft_serial[SHA204_SERIAL_SZ] = {0xAA,0xAA,0xAA,0xAA,0xAA,0xAA,0xAA,0xAA,0xAA};
MySigningAtsha204Soft signer(true, 0, NULL, soft_serial);
MyHwATMega328 hw;
MyTransportRFM69 transport;
MySensor gw(transport, hw, signer, RADIO_RX_LED_PIN, RADIO_TX_LED_PIN, RADIO_ERROR_LED_PIN);

The code in the node:

whitelist_entry_t node_whitelist[] = {
  { .nodeId = 0,
    .serial = {0xAA,0xAA,0xAA,0xAA,0xAA,0xAA,0xAA,0xAA,0xAA} }};
uint8_t soft_serial[SHA204_SERIAL_SZ] = {0x01,0x02,0x03,0x04,0x05,0x06,0x07,0x08,0x09};
MySigningAtsha204Soft signer(true, 1, node_whitelist, soft_serial);
MyHwATMega328 hw;
MyTransportRFM69 transport;
MySensor gw(transport, hw, signer);

In MyConfig.h I enabled MY_SIGNING_FEATURE and MY_SECURE_NODE_WHITELISTING.

Do you think it's correct ?

If I enable DEBUG_SIGNINGin MySigningAtsha204Soft.cpp, on reception of a message I got a SNOKand a W?. Why ?

David.

@carlierd Is this a duplicate of this thread? http://forum.mysensors.org/topic/2491/verify-fail-when-enabling-whitelist-in-signing-function
Lets continue in that one if so.

Hello !

It's not exactly the same thing. In this post I described what I want to do and how I implemented it. It's a global vision of what I understood or not correctly understood

We can continue on the previous post.

Well, then I do believe your vision is described in my signing thread
But let's focus on the problem you describe in the other thread.
