摘　　要：针对P2P网络中现有公钥体制在数字签名、身份认证中速度慢的缺陷,提出一种加快公钥体制速度的策略.该策略结合了离散对数加密与矩阵序列加密的特征,易于实现,安全强度高,计算量小.文中对该策略的相关工作进行了介绍,对策略进行了描述,较详细地分析了策略的安全性及其实现速度.并与其他公钥体制进行了理论上与实测上的比较,证明了在公钥体制中,该策略的速度比椭圆曲线算法(ECC)速度快.In this paper,according as the characteristics of P2P network and the flaw of slow speeding about the digital signature and the authentication,present a strategy of accelerating the speed of public key system.The strategy combines the characteristic of discrete logarithm and matrix queue and it is realized easily and has small computational with strong security.in this paper,First,we introduce the related work,then describe the strategy and analysis detailedly its security and the reality of speed.At last,we compare the public key system with other theoretical by experimenting.Prove that the speed of the strategy is faster than the elliptic curve algorithm（ECC） in the public key system.
