Analysis and Improvement of Forward Secure Proxy Blind Signature Scheme
摘要
Abstract
Through the security analysis of the forward secure proxy blind signature scheme proposed by Manoj et al., this study found out that the scheme can not resist the forgery attack during proxy phase and signature gen-eration phase. In order to avoid these attacks, an improved forward secure proxy blind signature scheme was pre-sented based on DLP. The improved scheme overcame the drawbacks in the original scheme by embedding one-way hash function in short signature during proxy phase and improving signature generation phase. In the effi-ciency, the improved scheme was more secure with one more hash operation compared with the original scheme, which has verifiability, distinguishability, unforgeability, nonrepudiation, etc.关键词
