摘要
提出了一种新的前向安全的群签名方案,该方案的优点在于在实现前向性时不需要确立群管理员公钥的有效期,从而具有无界时间段的前向安全性,使得群签名方案在实现前向安全性时更具灵活性且实现的效率较好。
Since 2001, when D. X. Song firstly proposed the conception of forward-secure group signature scheme, several schemes have been brought forward. A new forward secure group signature scheme is presented. Its advantage lies in that the valid deadline of group manager＇s public key is not needed to be established when realizing the forward property. Thus it has the forward secure of no-limlted time. So the forward-secure group signature scheme is more agile and more efficient.
