| 摘 要： | 失败-停止签名是一类不依赖于攻击者计算能力假设的数字签名技术，即使攻击者拥有无限的计算能力，签名者也可以证明一个签名是伪造的。目前，基于RSA密码体制的失败-停止签名已经比较成熟，我们在此基础上提出了一种新的门限失败-停止签名方案，并对此方案进行了安全性分析。该方案基于可证明安全的RSA失败-停止签名，具有欺骗检测（验证部分签名）和能够显示而高效地证明伪造性等特点。

| Abstract: | The security of fail-stop signature schemes does not rely on assumption of computational power of forger.Fail-stop signature schemes provide security even if a forger possesses unlimited computation power by enabling the sender to provide a proof on forgery if it occurs.Currently the study of fail-stop signature based on RSA has been mature.We construct a new threshold fail-stop signature scheme based on it and provide security analysis of the scheme.Our scheme is based on a provably secure RSA fail-stop si... |
