一种基于身份的无可信中心的代理签名方案
ID-based proxy signature scheme without trusted center
摘要
Abstract
Based proxy signature,a new ID-based proxy signature without trusted PKC is proposed.Analysis of the security of the proposed scheme shows that it satisfies the basic security requirements of proxy signature, and the valid proxy signature generated by the proxy signer on behalf of the original signer can only be verified and thus accepted by the receiver nominated by the original signer.In the communication protocols, the processes of signature,authentication,encryption and decryption are simultaneously completed in a single protocol process and the conventional crypto graphical protocols in data transferring are greatly simplifiedwithout in fluencing the security of system.Further detailed analyses also justify the brevity of scheme, security,high efficiency,and considerable reduction in systemoverheads regarding software and hardware application.关键词
