Abstract:

Network 5.0 is a future-oriented data network communication architecture. One of the most basic features of this network architecture is the ability of ensuring endogenous security and trust. Based on this technical feature, this paper first discusses the current situation of network security threats and the shortcomings of traditional network security protection models. Then, it analyzes and sorts out the security requirements of major application scenarios of Network 5.0. It also proposes the security and trust architecture and implementation mechanism for Network 5.0, and discusses the typical key technologies for security of Network 5.0. Finally, it introduces the relevant practices carried out in the field of Network 5.0, and proposes suggestions for future research directions.

Key words: Network 5.0, endogenous security, trusted access, trusted identity
