摘要: 提出了两个新的数字签名方案,它们的安全性同时基于离散对数和素因子分解两个困难问题,并各有特点.对两个方案的性能和可能遭受到的攻击进行了详细讨论.

关键词: 因子分解, 离散对数, 数字签名

Abstract: Two new digital signature schemes whose security are based on both discrete logarithms and factorization are proposed.The paper also considers some possible attacks to the schemes,shows that the two schemes are more secure than the ElGamal's signature scheme and the Rabin's signature scheme.

Key words: factorization, discrete logarithm, digtal signature
