Conclusion of 5g network6/7/2023 Researchers found that the SDN-based 5G network attack prevention scheme avoids the centralized exposure of sensitive data, improves security, reduces computational overhead, and simplifies encryption logic. Second, concerning attack detection, the signal is identified by using the imperfections and differences of equipment manufacturing based on the above security structure, preventing the attacker from further harming the sensitive data leaked. First, in terms of attack prevention, the 5G network security structure is proposed to replace the plaintext information commonly used in the original system with Ciphertext based on software defined network (SDN), thereby alleviating the security risks of the data dimension. The purpose is to guarantee the security of fifth generation mobile communication technology (5G) network in power Internet of Things environment and improve the ability of wireless network communication to resist attacks. 6North China University of Technology, Beijing, China.5State Grid Liaoning Electric Power Co.4DigApis Information Security Technology (Jiangsu) Co.3Key Laboratory of Trustworthy Distributed Computing and Service (BUPT), Ministry of Education, Beijing University of Posts and Telecommunications, Beijing, China.2Liaoning Electric Power Research Institute of State Grid Corporation of China, Shenyang, China.1School Of Computer Science and Engineering Northeastern University, Shenyang, China.Tong Li 1,2, Hai Zhao 1, Shouyou Song 3,4*, Chao Yang 5, Chunlai Du 6,7 and Yang Liu 2
