Zigbee AES key sniffing

[Travis Goodspeed] posted a preview of what he’s working on for this Summer’s conferences. Last weekend he gave a quick demo of sniffing AES128 keys on Zigbee hardware at SOURCE Boston. The CC2420 radio module is used in many Zigbee/802.15.4 sensor networks and the keys have to be transferred over an SPI bus to the module. [Travis] used two syringe probes to monitor the clock line and the data on a TelosB mote, which uses the CC2420. Now that he has the capture, he’s planning on creating a script to automate finding the key.
