Question about security signing, and when it is "applied"



  • Hi,

    Background.
    I have a smart thermostat node, which is signed, and requires signed messages from the gateway.
    As a nice to have, as part of the initialisation, time is requested., this is used to post the boot time in a text field back in the controller.
    when developing this version of the thermostat, I didn't use signing, until deployment, and all proceeded more or less as expected. After deployment however, it became apparent that "booting" was taking a considerable period of time ( up to 3 mins on one occasion) I narrowed this down to the infinate loop of getting the time I had created (now limited to 5 tries) in the startup().
    Prior to enabling the signing, the booting would complete in circa 40 secs ( I have 10 or so child objects and use wait(250); between presentations).

    My question : Is signing applied to ALL communications, including presentations, or is it only applied after the initial preambles, and utilised only on "received" commands( requested or directed)?

    Looking at the log of the node, once connected back up, the signing " NONCE KEY"t ype packets didn't appear until after much time, and definitely not at the start of the logs.

    here is an example log
