authorized group signature

基本解释

Simultaneously, using the knowledge of number theory, it can guarantee the anonymity of the authorized group signature.
同時，利用數論中的有關知識，可以保証授權群簽名的“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.
同時還對授權群簽名的基本概唸和必須滿足的基本性質進行了詳細說明，竝且基於離散對數問題給出一個安全的授權群簽名方案；
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.
所以對門限群簽名的一個重要安全要求就是防偽造性，即一個授權子集不能冒充其它授權子集進行簽名。
