| 摘 要： | 提出了一个基于双线性时的前向安全的代理签名方案,方案能实现即使代理签名人的密钥被泄露,之前所产生的代理签名依然有效.该方案是基于双线性签名体制构造的,具有签字短、安全、高效等优点,不仅能有效抵制任何第三方和原始签名人的伪造攻击和代理签名人的代理权滥用,而且能满足强代理的一切性质.最后,对所提出方案的安全性做了详细分析和讨论.

| Abstract: | A forward secure proxy signature scheme based on bilinear pairings was proposed.In the scheme,the former proxy signature is still valid even if the secret keys of proxy signers are lost.The scheme is based on bilinear pairings,which can make signature short,secure and efficient.The scheme can not only effectively resist the forgery attacks from any third party and original signer's and misusing of the proxy signature right from proxy signers,but also satisfies all security properties of strong proxy signatu... |
