5G Wireless Communication Network Security System Encryption based on DES Algorithm

With the rapid development of Internet technology and the enrichment of Internet of Things services, wireless communication networks have developed into more efficient, lower energy consumption and higher information security communication networks. The fifth-generation mobile communication technology (5G) comprehensively uses a variety of new wireless technologies, based on a heterogeneous and complex network structure, and provides network support for the access of massive devices, rich wireless services, and data traffic requirements of orders of magnitude. 5G has the characteristics of high transmission rate and low latency, and requires a higher level of network security. The traditional key encryption mechanism with high complexity is restricted in 5G networks, so the DES algorithm has been widely used in strengthening the security of 5G wireless communication networks.
