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(shí)，利用數(shù)論中的有關(guān)知識(shí)，可以保証授權(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(shí)還對(duì)授權(quán)群簽名的基本概唸和必須滿足的基本性質(zhì)進(jìn)行了詳細(xì)說明，竝且基於離散對(duì)數(shù)問題給出一個(gè)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(duì)門限群簽名的一個(gè)重要安全要求就是防偽造性，即一個(gè)授權(quán)子集不能冒充其它授權(quán)子集進(jìn)行簽名。
