| 摘 要： | 提出了一种基于身份的可认证群组密钥协商方案ASTR，把日前通信开销最小的方案STR与基于身份的密码技术结合起来，不仅保持了STR在性能方面的优势，而且提供了隐含密钥认证和完善前向保密等安全属性，弥补了STR不能抵抗主动攻击的不足。

| Abstract: | An identity-based authenticated group key agreement scheme named ASTR is presented. ASTR combines the most communication- efficient scheme STR and identity-based encryption, which makes it not only being communication-efficient but also providing some security attributes such as implicit key authentication and perfect forward secrecy, etc. STR cannot resist active attacks, While ASTR can. |
