The Use of Group Signatures to Achieve Revocable Anonymity of Electronic Cash Program
Xue Ji-ming · Computer Knowledge and Technology · 2009
ACJT group signature is a proven and very effective anti-collusion and security group signature scheme,but it can not prevent extortion. According to the program,through a combination of new knowledge of cryptography,designed a program by the group signature which can be revoked anonymity of e-cash program,and it can effectively prevent the duplication of spending and anti-extortion. This paper introduces the design of the program with the algorithm and performance analysis,and finally on the overall efficiency of the program summarized.
