Extracting Keys from SoC Zigbee Chips

by Travis Goodspeed <travis at>

Last week, at Black Hat Briefings, I presented a short paper entitled Extracting Keys from Second Generation Zigbee Chips. Though brief, the paper is vitally important reading for anyone shipping a product with chips from Chipcon and Ember. The paper includes a method by which keys may be extracted from these chips, as well as a software method for defending Chipcon devices against the attack. All EM2xx chips are vulnerable, as are all of the 8051-based Chipcon radios, such as the CC2530. This is not the same as my attack against first generation, discrete radios.
