对一个门限签名方案的进一步分析与改进
Further cryptanalysis and improvement of threshold signature scheme
摘要
Abstract
This paper presents a security analysis of Gao et al's (/,n) threshold signature scheme without trusted party, which can not resist outward attack and public-key attack. Besides, it also improves Gao et al' s scheme and proposes a new (t,n) threshold signature scheme. The improved scheme doesn' t need a trusted center, its key generation only runs an interactive protocol among all the participants, and overcomes the original scheme' s weakness. The results prove it is secure and effective.关键词
