摘要
分析了四类离散对数数字签名算法,分别给出了改进算法,证明了正确性和不可伪造性,与已有方案进行了复杂度比较,签名效率有不同程度的提高。
Four discrete logarithm digital signature algorithms were analyzed,and four improvement measures were given.The correctness and unforgeability were proved.The efficiency of the algorithm is increased significantly compared with existing signature algorithms.
