【摘要】 基于身份和双线性对技术,构造了一种的高效环签名方案。对于任意大小的参与签名者的集合,该方案仅需两次配对运算。进行预计算后,减少了许多加法运算和数乘运算的开销,可以进一步提高效率。与现存的许多环签名方案相比,新方案在性能上具有明显的改进。在随机预言模型中,新方案是可证安全的。更多还原

【Abstract】 Constructing an efficient ring signature scheme based on identity and bilinear pairings,this scheme only needs 2 pairings op-erations not matter of the size of collection of participating signers.After pre-computations,it can reduce the computational cost of adding operations and scalar multiplication operations and improves its efficiency.Comparing with the existing many ring signature sche-mes,the new scheme’s performance gets improved greatly.In the random oracle model,the new scheme is provably secure.更多还原
