Abstract
This paper analyzes the existing security of the forward secure ring signature scheme, points out that the scheme exists security omission because of lacking forward security. Aiming at these problems, it proposes an improved forward-security ring signature scheme. The defect that the original scheme is signed with constant is overcome by changing the algorithm of ring signature. The algorithm combines the updating secret key and ring signature. The analysis of security and efficiency shows that the improved scheme has forward security, unconditional anonymity and resisting forging attack, as well as higher signing efficiency.关键词
