authorized group signature

基本解釋

Simultaneously, using the knowledge of number theory, it can guarantee the anonymity of the authorized group signature.
同時，利用數(shù)論中的有關(guān)知識，可以保證授權(quán)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(quán)群簽名的基本概念和必須滿足的基本性質(zhì)進(jìn)行了詳細(xì)說明，并且基于離散對數(shù)問題給出一個安全的授權(quán)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(quán)子集不能冒充其它授權(quán)子集進(jìn)行簽名。
