Analysis and improvement of threshold signature scheme without trusted party
摘要
Abstract
The security weaknesses of the threshold signature scheme without a trusted party worked out by Wang Bin and Li Jianhua are summed up.The radical reason is that the private key is dissevered and degenerately used in the signature process.As a result, an improved scheme is proposed which avoids the weaknesses and improves the security.It is proved that the proposed scheme can resist conspiracy attacks and forgery attacks and can provide anonymity and traceability at the same time.关键词
