Security from Legacy Wireless Systems to 5G Networks
Dongfeng Fang, Yi Qian, Rose Qingyang Hu · 2023
This chapter provides an introduction to the evolution of wireless network security, covering the security architecture and security services of the second generation (2G) to the fifth generation (5G) of wireless networks. Security services in 2G system such as global system for mobile communications include user authentication, communication encryption, user anonymity, and detection of stolen/compromised equipment. Security attacks can be categorized into two main types based on their attack features: passive attacks and active attacks. By introducing evolved NodeBs, 4G long-term evolution also provides handover security between different eNBs to ensure the authentication and key management. Moreover, handover security between 4G and legacy systems is also provided. Many of the research work focused on improve the handover performance with required security. Finally, the chapter gives an overview on the evolution of wireless security architectures from 3G to 5G systems.
