ID-based Authenticated Group Key Agreement Protocol
基于身份的认证群密钥协商协议

An authenticated group key agreement (AGKA) scheme allows a group of users in a public network to share a session key which may later be used to achieve desirable secure communication.According to various authentication flavors by using asymmetric techniques,the previous AGKA protocols are sorted PKI/CA-based ones that most cost of computation is modular exponentiation (or dot multiplication) and ID-based ones which are implemented by using pairing.Compared with PKI/CA-based AGKA,ID-based authenticated AGKA...
