Cryptanalysis of Efficient Unlinkable Secret Handshakes for Anonymous Communications
Iosr Journals, Preeti Kulshrestha1, Arun Kumar Pal1 · Figshare · 2015
Several unlinkable secret handshakes schemes have been proposed in recent years. As performing the successful secret handshakes is essentially equivalent to computing a common key between two interactive members of the same group. Therefore secret handshakes scheme is a key agreement protocol between two members of the same group. So it is necessary for a secret handshakes scheme to fulfill security requirement of secret handshakes protocol as well as key agreement protocol. In this Paper, we show that the Ryu et al. unlinkable secret handshakes scheme does not provide key compromise impersonation resilience which is an important requirement in ID-based two party authenticated key exchange scheme.
