A Novel Probabilistic Passive Attack on the Protocols HB and HB+

Jose Carrijo and Rafael Tonicelli and Hideki Imai and Anderson C. A. Nascimento

Abstract

We present a very simple probabilistic, passive attack against the protocols HB and HB+. Our attack presents some interesting features: it requires less captured transcripts of protocol executions when com- pared to previous results; It makes possible to trade the amount of required transcripts for computational complexity; the value of noise used in the protocols HB and HB+ need not be known.
