title = "Password-based group key exchange secure against insider guessing attacks",
abstract = "Very recently, Byun and Leo suggested two provably secure group Diffie-Hellman key exchange protocols using n participant's distinct passwords. Unfortunately, the schemes were found to be flawed by Tang and Chen. They presented two password guessing attacks such as off-line and undetectable on-line dictionary attacks by malicious insider attacker. In this paper, we present concrete counterrneasures for two malicious insider attacks, and modify the two group Diffie-Hellman key exchange protocols to bo secure against malicious insider password guessing attacks. Our counterrneasures do not require additional round costs, hence they are efficient.",
