public key infrastructure system

Public key Infrastructure (PKI) supports public key crypto system and digital signature on the national information highway and would play an important role in providing those services.

公钥基础结构支持国家信息高速公路上的公钥密码体制和数字签名，将在提供这些服务中起非常重要的作用。

The solution, which makes use of the method of combining PKI with S/MIME, establishes a system of secure E-mail transfer, according to the application principle of Public Key Infrastructure(PKI).

该方案依据PKI（公钥基础设施）的应用原理，采用PKI与S MIME相结合的方法，建立了基于PKI的安全邮件传输体系。

The scheme was based on the public key infrastructure(PKI) architecture with system security achieved by various means such as random numbers, salt, and multiple round iterations.

该方案基于公钥基础设施体系架构，采用了随机数、“盐”和多轮迭代等手段保证系统的安全性，并且通过在客户端进行密钥生成和加解密操作的方式实现了系统的可扩展性。
