A Certifiable Representative Digital Signature Approach Based on Forward Security
Xiaohua Tang · Computer Technology and Development · 2007
The present representative digital signature approaches are based on discrete logarithm problem and large number factor decomposition.The idea of the digital signature approach proposed in this paper includes the forward security and non-refutation of representative signature.The approach is based on elliptic curve discrete logarithm problem.The paper made an analysis on the complexity and security of the proposed signature approach.The analytical result shows that the approach is safe and feasible,and it extends the cipher function of elliptic curve codes.
