摘　　要：容忍泄露是指为了增强签名方案的鲁棒性,允许方案泄露部分秘密信息,适用于设备和通讯线路均没法完美保护的大部分场合.短签名长度一般只有普通签名一半的签名长度,可以大大降低窄带实时交互的系统的通讯数据量.提出了一种待签名信息关联签名密钥的短签名方案,该方案具有容忍部分泄露的特性,对方案的效率和安全性进行了分析,证明了方案在容忍泄露预言机下是安全的,实验结果表明该方案具有较好的性能,适用于传输带宽受限的应用场合.Leakage tolerance refers to allowing the scheme to leak some secret information to enhance the robustness of the signature scheme,which is suitable for most occasions where the equipment and communication lines cannot be perfectly protected.The length of the short signature is generally only half that of the ordinary signature,which can greatly reduce the communication data volume of the narrowband real-time interactive system.This study proposes a short signature scheme for the signature key associated with the information to be signed,and the scheme is tolerant to partial leakage.The efficiency and security of the scheme are analyzed,and the security of the scheme is proved under the tolerant leak oracle.The experimental results show that the scheme has good performance and is suitable for applications with limited transmission bandwidth.
