组密钥协商完成在一组成员之间协商密钥,从而有效地保护组内通信。密钥协商能够保证即使有第三方在对本密钥协商有着全面的了解和能够窃听到了所有通信过程的消息,也不能计算出这个密钥。目前有许多成熟的算法,文章中介绍了一种优化的GDH组密钥协商算法smart-GDH。
Group key agreement to complete a group of members to negotiate the key, so as to effectively protect the group communication. Key agreement can guarantee that even if there is a third party in this key agreement has a comprehensive understanding and can eavesdrop on all the communication process of the message, it can not calculate the key. There are many mature algorithms, the article describes an optimized GDH group key agreement algorithm smart-GDH.
