网络通信的两种加密技术

Two Cryptographies about Network Communication

数据加密技术是所有通信安全的基石,数据加密过程是由形形色色的加密算法来具体实现的,主要可分为常规密码算法和公钥密码算法。通信网络的两种常用加密技术是链路加密和端端加密,两者结合使用,扬长避短是一种有效的网络安全方法。

Data encryption technique is the foundation stone of all communication securities. The procedure of data encryption is achieved by various data encryption algorithms, which are classified mainly into traditional secret-key algorithms and publickey algorithms. Two general data encryption techniques of communication network are link encryption and end-to-end encryption, and combining two techniques is an effective measure of network security because the measure can make amends for its weaknesses by exploiting its strengths.
