摘　　要：计算机网络的发展与普及,使得人们对网络安全的要求也越来越高,PKI正是能够实现信息安全的热门密码技术.NTRU算法是一个新的公钥密码体制,它具有密钥产生容易、高速和低需求等特点,它的加密使用基于多项式代数和对数p,q约化模的混合系统,而解密使用基于概率论的非混合系统.文中提出了一个基于NTRU和NTRUSign的PKI模型,在此模型中一个主体拥有两个证书,且证书的颁发由两个子CA进行,这样减轻了根CA的负荷,讨论了此模型具有的特点,从而使这个模型具有一定的实用价值.With the development of computer network, there are higher demands for the computer network security. PKI is the popular technology for the information security. NTRU is a new public key eryptosystem. Its features reasonably short, easily created keys, high speed, and low memory requirements. The eneryption procedure uses a mixing system based on polynomial algebra and reduction modulo two p and q. The decryption procedure uses an unmixing system whose validity depends on elementary probability theory. A model of PKI based on NTRU is proposed, and then the character of this model is analyzed, so, the practicality of the model is validated.
