聚合签名方案的安全性分析与改进
SECURITY ANALYSIS AND IMPROVEMENT OF AGGREGATE SIGNATURE SCHEMES
摘要
Abstract
Aggregate signature can reduce the cost of signature verification and the length of the signature.First, we analyzed security of three certificateless aggregation signatures.We allowed certificateless public key cryptosystems to attack them.These attacks: general user public key replacement attack and malicious key generation center KGC forged attack.And Chen program and Yu scheme cannot resist the public key to replace the attack, nor resistance to KGC passive attack.Zhang program cannot resist KGC active attack.Through the specific attack algorithm and cause analysis, proved that the program is not safe.We improved the Zhang''s scheme to strengthen the security compared with the original program.关键词
