Security Analysis of an ID-Based Key Agreement for Peer Group Communication
Duc Liem Vo, Kyungbaek Kim · IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences · 2007
Pairing based cryptography has been researched intensively due to its beneficial properties.In 2005, Wu et al.[3] proposed an identity-based key agreement for peer group communication from pairings.In this letter, we propose attacks on their scheme, by which the group fails to agree upon a common communication key.
