Cryptanalysis of Two ID-based Authenticated Key Agreement Protocols from Pairings

Kyung-Ah Shim

Abstract

Recently, a number of ID-based two-party authenticated key agreement protocols which make of bilinear pairings have been proposed \cite {CJL,MB,Sh,S,X}. In this paper, we show that the Xie's protocol \cite {X} does not provide implicit key authentication and key-compromise impersonation resilience. Also, we point out the vulnerability of the Choi {\it et al}'s protocol \cite {CJL} against signature forgery attacks.
