摘要
数据加密是实现网络安全的关键技术之一 .常用数据加密算法有其难以克服的缺点———加密和还原运算复杂 ,时间开销大 ,不适应高速实时通信的需要 .为此 ,设计了一种新的数据加密方法———基于随机性原理变换包长、密钥和加密运算控制 ,克服了常用数据加密算法的缺点 ,运算简单 ,加密效果好 ,它适合于多路复用器等高速通信仪器的数据加密 .
Data encryption is a pivotal technology of net security. There are some defects that are difficult to overcome in common data encryption algorithm. Its computing is complex and takes a long time, which can not meet the needs of real time communication with high speed. The author has designed a new data encryption method, i.e . changing packet length, secret key and encryption algorithm control based on random theory. This conquers defects of common data encryption algorithm and makes computing simple and encrypting very effective. It can hardly be decrypted without the secret code. And it is suited for data encrypting of a multiplexor apparatus. [
