With the rapid development of computer network technology, network security issues have become increasingly prominent. Therefore, it is very necessary to apply network security protocols to the field of computer communication. Based on the analysis and research of network security protocols, this paper discusses their applications in the field of computer communication. This paper first elaborates on the concept and classification of network security protocols, and provides a detailed analysis of their application scenarios and functions in the field of computer communication. Finally, the development prospects of network security protocols in computer communication technology were discussed.
