Analysis of the Application of Data Encryption Technology in Computer Network Security

Abstract

The application of data encryption technology in computer network security has become an important means to protect sensitive information and ensure secure data transmission. This paper first provides an overview of data encryption technology, including basic concepts, classification of encryption algorithms, and encryption principles. A comparison between symmetric and asymmetric encryption algorithms is also presented. The paper then explores the application of data encryption technology in network transmission, network storage, and network communication. In addition, the basic concepts of digital signature technology are introduced, along with its implementation modes and application scenarios in network security. Furthermore, the paper discusses the basic concepts of security protocols and provides detailed explanations of the TLS/SSL security protocol and IPsec protocol. The development trends of data encryption technology are also analyzed, including the combination of multiple technologies, big data encryption, quantum encryption technology, and verification encryption. In conclusion, the application of data encryption technology in computer network security is diverse and will continue to play an important role in future developments.
