Welcome to the resource topic for 2003/122

Title:
Cryptanalysis of Al-Riyami-Paterson’s Authenticated Three Party Key Agreement Protocols

Authors: 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.
