Dear editor,rnNumerous three-party authenticated key exchange (3PAKE)protocols have been presented,which allow the establish-ment of a secure session by utilizing a session key shared between two clients with the assistance of a server trusted by both the clients via an unprotected network communica-tion environment.The 3PAKE protocols can be applied to various scenarios,including mobile commerce environment.Recently,focusing on this topic,Islam et al.[1]presented an improved protocol (IAB-3PAKE) for mobile commerce envi-ronment,which remedied some flaws existing in Tan\'s pro-tocol[2].Unfortunately,the IAB-3PAKE protocol still ex-hibits the weakness of key compromise impersonation (KCI)attacks;an attacker can impersonate the server to share a session key with one of the clients if the client\'s long-term private key is acquired by the attacker.Further,with re-gard to the possible leakage of private keys,Wei et al.[3]reported that the private key can be recovered under some conditions.
