Title:
HB^N: An HB-like protocol secure against man-in-the-middle attacks
Authors: Carl Bosley, Kristiyan Haralambiev, Antonio Nicolosi
Abstract:We construct a simple authentication protocol whose security is based solely on the problem of Learning Parity with Noise (LPN) which is secure against Man-in-the-Middle attacks. Our protocol is suitable for RFID devices, whose limited circuit size and power constraints rule out the use of more heavyweight operations such as modular exponentiation. The protocol is extremely simple: both parties compute a noisy bilinear function of their inputs. The proof, however, is quite technical, and we believe that some of our technical tools may be of independent interest.
