Jessica Croft demonstrates RSS-based secret key establishment at Mobicom 2010

Nexus One Nexus OneAt Mobicom 2010 in Chicago, IL, Ph.D. Candidate Jessica Croft demonstrated the establishment of a shared secret keys on two Nexus One phones without the phones ever exchanging key data over the air. The two phones make measurements of the received signal strength (RSS) of the channel between them. The adaptive ranking-based uncorrelated bit extraction (ARUBE) method, first presented in a paper at the IPSN 2010 conference, is implemented and runs on Android. Jessica's work demonstrates the low computational complexity of the ARUBE method and will allow users to see how quickly secret key bits can be generated, and how reliably the secret keys agree. Jessica's demonstration occurred on Wednesday, September 22, 2010, in the poster and demo session.
