authorized group signature

基本解释

Simultaneously, using the knowledge of number theory, it can guarantee the anonymity of the authorized group signature.
同时，利用数论中的有关知识，可以保证授权群签名的“匿名”性．。
Thirdly, we explained the fundamental concepts and properties of authorized group signature in detail and propounded a secure authorized group signature based upon the discrete logarithm.
同时还对授权群签名的基本概念和必须满足的基本性质进行了详细说明，并且基于离散对数问题给出一个安全的授权群签名方案；
So, an important security requirement to a threshold group signature is nonforgeability, i. e. an authorized subset should not impersonate another authorized subset to generate signature.
所以对门限群签名的一个重要安全要求就是防伪造性，即一个授权子集不能冒充其它授权子集进行签名。
