混合结构的数字多重签名算法

Digital multi-signature algorithm with mixed structure

分析了一种比较普遍的混合签名结构,提出一种安全高效的归一化结构多重数字签名算法。该方法将广播结构签名虚拟成有序节点,并引入了一个签名验证中心(CSV)参与运算。对比测试表明,该算法安全性和效率都较高,能够解决多种多重结构的数字签名。

With the development of informatization,the digital multi-signature mixed with sequential and broadcast structures has become a research hotspot.This paper firstly analyzed a common mixed signature structure,and then presented an algorithm with unitary structure,which is more effective and secure.For this algorithm,the broadcasting was regarded as dummy sequential one,and led a Center of Signature and Verification （CSV） into operation.The security and efficiency of the algorithm is proved excellent through contradistinctive test,so the algorithm can resolve digital multi-signature of multifarious multistructure.
