On the security of an identity-based authenticated group key agreement protocol for imbalanced mobile networks

Haiyan Sun

Abstract

Recently, Islam and Biswas proposed a pairing-free identity-based authenticated group key agreement protocol for imbalanced mobile networks. However, in this letter, we point out that this protocol cannot resist passive attack, and cannot provide forward secrecy for joining operation and backward secrecy for leaving operation.
