Abstract:

Sixth-generation (6G) mobile communication networks are evolving toward ubiquitous connectivity, pervasive intelligence, and the convergence of diverse application scenarios, making security risks increasingly complex. An integrated security risk analysis framework comprising three categories—the evolution of inherited risks, AI-induced risks, and risks introduced by emerging technologies—is developed to examine the evolution of existing risks in 6G scenarios, the derivative risks arising from the involvement of artificial intelligence in network operations, and the incremental risks introduced by emerging technologies such as digital twins. The analysis indicates that 6G security should be designed in tandem with the network architecture and intelligence mechanisms to strengthen dynamic defense and built-in security capabilities. The findings can provide a reference for research on 6G network architectures, security design, and standardization.

Key words: 6G, mobile communication network security, agent, risk analysis
