  • Abstract
    In a recent paper, Dutta and Barua presented a group key agreement protocol in dynamic setting. The protocol allows users to efficiently join or leave a group and was believed to be provably secure. In this letter, we point out a flaw in the Dutta-Barua dynamic group key agreement protocol.
