摘要: 将前向安全的概念引入到(t1,n1,t2,n2)门限多代理多签名方案中,利用双线性映射,给出一种基于身份的前向安全的门限多代理多签名方案。该方案能实现各代理签名密钥的定期更新,使得即使代理签名人的代理签名密钥被泄露,以前产生的多重代理签名依然有效。最后,对方案的性能进行了分析。

Abstract: An identity-based forward secure (t1,n1,t2,n2) threshold multi-proxy multi-signature scheme is proposed combining the concept of forward security with threshold multi-proxy multi-signature from bilinear pairing.In the scheme,the proxy key can be renewed periodically.An adversary cannot forge multi-proxy signature pertaining to the past even if all the current proxy signers’ keys are leaked.At the end of this paper,the performance of the scheme is analyzed.
