Abstract :
A password authenticated key exchange (PAKE) is a secure and authenticated bilateral key-exchange scheme, which uses a memorable password. Most of the key exchange protocols have high computational complexity leading complex hardware implementations. Though CA based PAKE is easily realizable in hardware, we observe that it has serious security flaws. In this paper we propose RPAKE, a secure PAKE scheme, basing on the features of reversible cellular automata (RCA). Our analysis shows that RPAKE is immune against numerous attacks and its hardware realization is also simpler
