| 摘 要： | 前向安全的签名方案在当前签名密钥泄漏后,也能确保用户此前所作签名的合法性;而环签名能保证签名用户的无条件匿名性。基于保护前向安全性和无条件匿名性的要求,本文利用双线性对提出了一种新的前向安全的环签名方案,并在标准模型下证明其能抵抗伪造签名攻击,适用于对安全性能要求较高且匿名的场合。

| Abstract: | Ring signature can provide unconditional anonymity of the signer.Forward secure signature scheme is to preserve the validity of past signatures even if the current private key has been compromised.A new ring signature scheme based bilinear pairings is proposed from Forward secure signature and ring signature.This scheme is existentially unforgettable in the standard model and unconditionally anonymous,so it is suitable to the application of high security and anonymity. |

| Keywords: | digital signature ring signature standard model bilinear pairing forward secure |
