The improvement of data encryption technology in computer network security

Abstract

With the continual advance of innovation and science and technology in Japan, Japan entered the information age. The development of computer technology and information technology brought us a lot of convenience in our work and life, its security problem has also caused a lot of trouble to us. With the improvement of people's attention to computer network security, data encryption technology is gradually used by people. Data encryption technology is a technology that encrypts the information exchanged between users or enterprises. Data encryption techniques can effectively guarantee user safety during use of a computer network. Then, in this paper, the concept of the data encryption technology, the basic algorithm, the main technology type, and the application in computer network security were arranged, and the research level of the data encryption technology in the computer network security was raised.
