代理多重签名和指定接收人的代理多重签名方案

Proxy multi-signature and designated-receiver proxy multi-signature schemes

设计了一种基于椭圆曲线离散对数问题(E lliptic Curre D iscrete Logarithm Problem,ECDLP)的代理多重签名方案,该方案不仅满足了代理多重签名的所有安全要求,而且避免了签名生成和签名验证过程中费时的求逆运算。在此方案的基础上提出了一种新的指定接收人的代理多重签名方案,并对其安全性进行了分析。

Proxy multi-signature scheme was first designed on ECDLP. This scheme can not only satisfy all the security requirements, but also avoid wasting time on inversion operations of its signature generation and verification. Then a new designated-receiver proxy signature scheme was proposed, and its security was analyzed.
