摘要
利用双线性对和基于身份密码体制理论,提出基于身份的前向安全门限代理签名方案。该方案实现了代理签名密钥的定期更新,有效提高了代理签名的安全性。分析结果表明,该方案安全可靠,具有前向安全性、后向安全性和匿名性。
In terms of bilinear pairing and identity-related cryptography, a forward secure threshold proxy signature scheme is pro- posed. The scheme realizes the periodic updating of the proxy signature key, and effectively improves the security of proxy signa- ture. The analysis results show that the proposed scheme is safe and reliable, and has forward security, backward security and anonymity.
