摘要
文章提出了一种关于数字签名批验证的新方法,按此方法设计的批验证方程是动态方程,而以前的批验证方程是静态方程,仅是新的批验证方程的一个特例.按以前的批验证方法,只有少数几种数字签名被设计成批验证方式,结果都存在伪造攻击,是不安全的,而按新的批验证方法,每一种数字签名都可以被设计成批验证方式,而且符合安全批验证协议的要求.在执行新的批验证时,不会改变验证的计算模式和复杂度,只是可能会增加少许计算量,因此新的批验证设计方法是可行的.
A new solution to batch verifying multiple digital signatures is proposed.By the new solution,the batch verifying equation is dynatic,but the previous one is static and as a special case of the new solution.By the old solution,only a few digital signature had been carefully conveyed to batch verifying,but they were all not safe.The most important is every safe digital signature scheme can been conveyed to a safe batch verifying multiple digital signatures protocol by the new solution.When batch verifying multiple digital signatures,the computing mode and complexity is not changed,only perheps adding a little computing quantity.So the new solution is feasible.
