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.
Aiming at the shortcomings of the existing public key system in digital signature and identity authentication in P2P networks, a strategy of accelerating the speed of public key system is proposed.This strategy combines the features of discrete logarithm encryption and matrix sequence encryption, which is easy to implement, High security and low computational load.This paper introduces the related work of this strategy, describes the strategy, and analyzes the security of the strategy and its speed of implementation in detail.Moreover, The comparison shows that in the public key system, this strategy is faster than the elliptic curve algorithm (ECC).
