一种基于PKI的企业即时通信安全方案

A Secure Enterprise Instant Messenger Scheme Based on PKI

企业即时通信系统是即时通信技术在企业中的一种应用,面临计算机病毒,身份识别、数据机密性、真实性、完整性和不可否认性等安全问题。PKI是基于公钥理论和技术的基础安全平台。本文设计了一种基于PKI的企业即时通信系统安全架构,并采用ECC公钥密码体制、IDEA对称密码体制和HASH-1消息摘要算法,给出基于该架构的EIM系统身份认证、数据加密、数字签名等安全问题的解决方案。

Enterprise Instant Messenger（EIM） is an application of Instant Messenger on enterprise.It is facing many secure problems,such as,computer virus,authentication,data secret,reality,integrity and undeniable,and so on. PKI is a secure infrastructure based on public key theory and technology.This paper had designed a secure frame for Enterprise Instant Messenger based on PKI,and had presented the solution of authentication,data encryption and digital signature based on the frame for EIM.
