Application Research of Data Encryption Technology in Computer Network Information Security

Abstract

In order to ensure the rights and interests of computer users, a method of data encryption technology in computer network information security is proposed. According to the symmetric encryption AES algorithm, the ECC system has higher security, slower decoding speed, smaller storage space occupation, and lower bandwidth requirements. The experimental results show that the safety mode length can reach 5 : 1, 6 : 1, 10 : 1 or even 35 : 1. Conclusion. The use of a hybrid cryptosystem based on MD5, AES, and elliptic curve keys can effectively make up for various problems and loopholes encountered in data transmission in current network security, and improve the security of information transmission in today’s social network.
