Abstract

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.

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。
