| 摘 要： | 在基于对的可验证加密签名方案中,对运算是最为耗时的,故应在此类方案中尽量减少对运算的次数.为此,在给出一个新的基于对的签名方案的基础上,给出一个新的随机化可验证加密签名方案.新方案具有最少的对运算,即只有一个对运算.因此,与类似的方案相比,新方案更为有效.方案的安全性依赖于k-合谋攻击问题和离散对数问题困难假设.

| Abstract: | In the verifiably encrypted signature(VES) schemes from pairings,the pairing operations are the most time-consuming.So,in the schemes of such kind,the pairing operations should be less used.Based on a new construction of the signature scheme from pairings,a novel randomized and verifiably encrypted signature scheme is proposed,in which there is the least pairing operation.That is,there is only one pairing operation in the new scheme.Therefore,compared with the other randomized VES schemes from pairings,the ... |
