Cryptanalysis of Al-Riyami-Paterson's Authenticated Three Party Key Agreement Protocols

Kyungah Shim

Abstract

Recently, Al-Riyami and Paterson proposed four authenticated tripartite key agreement protocols which make use of Weil pairing. In this paper, we show that the protocols are insecure against the man-in-the middle attack, key compromise impersonation attack and several known-key attacks.
