基于混合加密算法的网络安全体系构造

A Network Security System Model Based on Mixed Encryption Algorithm

提出了一种基于混合加密算法的网络安全参考模型NetDESR。本文运用一种改进的DESR加密算法,采用分布式KDC分配方案,对通信报文加密方式进行签名,有效地防止了报文被非法窃听、篡改或伪造。本模型不仅适用于实时的、大数据传输的网络系统,而且实现了密钥管理、加密管理、数字签名以及身份认证等功能。

A network security system model-NetDESR, which is based on DES and RSA algorithm, is presented. It adopts distributed KDC management scheme. By generating a digital signature on the message by means of encryption, it efficiently prevents the message from being unlawfully overheard, fraudulently changed or fabricated. The model not only realizes key management, encrypted communication, digital signature and identity authentication, but also is fit for network system with real time and large data transfer.
