I was recently concerned about the security of SWAP-based systems. As you all know, SWAP on AVR systems is not really secure, and while there are a few security features present, and more for CC430, the stack doesn't provide a nice solution.
OTOH, the very fact that a single frequency and networkID is used makes it easy to detect any attempt of breach if the gateway logs the traffic. So I was just thinking of another approach, such as used for CB and other radio systems : if there is a shared secret between the panstamp and gateway, the latter could send a request to temporarily move to another "private" channel where a short-lived exchange could take place. The networkID could easily play that role.
Any opinion ? I'll try to use the poll feature to see if that rings a bell to the community. Don't hesitate to participate even after a few months !
