| 摘 要： | 本文提出了一种基于身份标识和双线性对的环签名方案,该方案较好地满足了环签名的安全需求,它不需要群建立过程,也无法撤销签名者的匿名性,因而可以有效地保护实际签名者的隐私权。同时,通过引入双线性对节省了计算开销,提高了方案的执行效率。与Zhang提出的环签名方案相比,本方案将环签名验证过程中所需的双线性对计算量由O(n)降低到O(1),计算效率更高。

| Abstract: | In this paper, we propose an identity- based ring signature scheme from bilinear pairings which fulfils perfectly the security requirements of ring signature. Our scheme can be considered as a simplified group signature with no group setup procedure, and no revocation mechanism against signer' s anonymity, thus signer' s privacy is guaranteed As compared with Zhang' s scheme, our scheme is a computational efficiency improvement for signature verification because the computational cost of bilinear pairings required is reduced from O(n) to O(1). |
