摘要:

由于网络环境的限制,异步网络系统的数据安全和与服务器的通讯安全是目前探讨的重要问题之一。分析了现有RSA、DES、MD5等加密技术,针对他们的一些不足,提出了一个异步网络系统的通讯安全方案,即通过综合运用各类数据加密技术,来提高数据的原始性、数据来源和去向的确定性,从而提高数据通讯的安全性。

Abstract:

Due to the limitation of network,the data communication security between clients and servers is an important issue in the asynchronous network system.The paper deeply analyzes the common encryption technologies,such as RSA,DES,MD5,and put forward a new communication security model based on their limitations.The proposed model applies multiple encryption technologies comprehensively to improve the quality of raw data,the reliability of data sources and whereabouts,thus increasing the security of data communication.
