新的基于身份认证的群密钥协商协议
Novel ID-based group authenticated key agreement scheme
摘要
Abstract
Group Key Agreement(GKA)protocol plays a key role in the construction of secure multicast channels. Because of the simplicity and efficiency of public key management, the ID-based Authenticated Group Key Agreement Protocol(AGKA)cryptosystem has become a hot research direction in recent years. This paper proposes a new Weil pairing and completely trigeminal tree based group key agreement protocol, designs the participants join-and-leave pre-protocol. Security analysis and performance analysis show that the new scheme satisfies all known security requirements. Compared with the existing schemes, the new scheme has obvious advantages in terms of performance.关键词
