New digital signature scheme based on discrete logarithm

Yao Guo-xiang

Abstract

The Discrete Logarithm Problem(DLP)was analyzed.Based on the discrete logarithm in the prime field,and combined with the elliptic curve DLP in the limited domain,a new digital signature was brought up.In addition,the security of this digital signature was analyzed and its performance was compared with other signatures.The results of comparison prove that this new digital signature based on discrete logarithm is more effective and secure than the others.
