Open publisher page 1 citations

Abstract

We analyze the security of asymmetric group key agreement (ASGKA) protocol in the universal composability (UC) framework. An ideal functionality that is suitable for ASGKA protocol is proposed. And we show that the ASGKA protocol securely realizes the proposed ideal functionality that can resist attacks by malicious insiders. The UC framework allows the protocols to guarantee their security under arbitrary protocol environment.
