Abstract: Recently, Cheng et al. proposed two tripartite key agreement protocols from pairings: one is certificate-based and the other is identity-based (ID-based). In this article, we show that the two schemes are vulnerable to the insider impersonation attack and the ID-based scheme even discloses the entities?? private keys. Solutions to this problem are discussed.
