一个前向安全代理签名方案的安全分析及改进
Security analysis and improvement of forward secure proxy signature scheme
摘要
Abstract
The existed forward secure proxy signature schemes have some security faults more or less. This paper analyzes the security of a forward secure proxy signature scheme proposed by Chen Ningyu et al. The analysis result shows that the scheme cannot satisfy the forward security, cannot resist the collusion attack of PKG and the proxy signer, the attack of public key substituted and the forgery attack of the distrusted PKG. To get over the faults of Chen Ningyu’s scheme, an improved forward secure proxy signature scheme is proposed in this paper. The improved scheme satisfies all the security requirements of forward secure proxy signature scheme, moreover, it can resist the collusion attack, the distrusted PKG’s forgery attack and the public key substituted attack.关键词
