摘要
提出了三种可认证会议密钥分配方案：基于ＭＲ型数字签名、基于加强型ＥｌＧａｍａｌ签名及基于身份的会议密钥分配方案，并分析、讨论了各自的安全性．这三种方案的基本思路都是由会议主席产生会议密钥并秘密地传送给会议参加者，会议参加者可以对会议密钥及其签发者进行认证．
This paper introduces three kinds of authenticated conference key distribution scheme: one based on MR_type digital signature, another based on enhanced ElGamal signature, and the third based on identity. The security of these schemes is also discussed. The schemes are based on the principle that the chairman of the conference generates a conference keys, sends them to all the conferees in secret, and that the conferees can authenticate the keys and the signers of the keys.
