Abstract:

Traditional authentication approaches rely on the secure distribution of secret keys and their security depend on computational hardness assumptions. However, they are not resistant to key compromise and mostly will no longer remain secure under quantum computing. Recently, non-cryptographic authentication techniques emerged as promising alternatives that are free of the above problems. In this talk, I will present our recent research progresses on exploiting hard-to-forge wireless physical-layer characteristics to build novel authentication primitives. First, I will describe a proximity-based device authentication scheme based on channel characteristics, namely the received-signal-strength variation profile (RSSV). Then, I will introduce a message authentication and integrity protection scheme in the insecure wireless channel, by exploiting infeasibility of complete signal-cancellation in the physical layer. Both techniques have applications in wireless network security, for example, key/trust establishment without prior contact, and are scalable to a large number of devices. Finally, I will outline some future challenges along this research direction.
