浅谈数据加密技术

On The Technology of Data Encryption

近年来 ,国内外在安全性方面的研究 ,还主要集中在两个方面 ,一是以密码学为基础的各种加密措施 ,如保密密钥算法和公开密钥算法 ;另一方面是以计算机网络特别是以Internet和Intranet为对象的通信安全研究。在保障网络通信安全方面所依赖的主要技术 ,仍然是加密技术。值得说明的是 ,数据加密技术已经渗透到了其它某些安全保障技术之中 ,并作为他们的重要基础。

In recent years ,The study of data safety at home and abroad mainly deals with two aspects, one is the various encryption measures based on cryptography , the other is the study of communication safety in computer network, especially in Internet and Intranet. The major technology in safeguarding network is still data encryption technology. Moreover ,this technology have influenced some other safety technologies , and is becoming the cornerstone of them.
