Security protection performance evaluation method applicable to core network of wireless power private network

Abstract

The invention discloses a security protection performance evaluation method applicable to a core network of a wireless power private network. The security protection performance evaluation method comprises the steps of firstly building a core network security protection performance evaluation system which comprises a terminal, multiple base stations, a switch, a secure encryption gateway, a core network, a network management server, a network management client and a secure access platform; then carrying out a data transmission security protection test of an S1 interface; carrying out a test for an HSS authorization server to refuse a service attack; carrying out a security controllability test for the core network; and carrying out a security test for the network management system of the wireless private network. By adopting the method, the security risk of the core network of the wireless power private network can be evaluated comprehensively, attack behaviors from malicious hosts to the core network of the wireless private network can be prevented efficiently, and the security robustness of the core network of the wireless power private network can be enhanced.

Description

technical field [0001] The invention relates to a safety protection performance evaluation method suitable for a core network of a private electric power wireless network, and belongs to the technical field of information safety protection evaluation of a power communication network. Background technique [0002] The main job of the LTE core network is to connect mobile terminals to external packet data networks in a packet manner. The main network elements of the core network include base stations, MME, HSS, S-GW, P-GW (PDN Gateway, PDN gateway) and PCRF (Policy and Charging Rules Function, policy and charging rule function). The base station provides an air interface connection for the terminal. The MME is equivalent to the manager of the core network and is responsible for all internal affairs (internal handover) and external affairs (cross-system interconnection). The HSS stores all service-related subscription data of users in the LTE network and provides User subscrip...

Problems solved by technology

[0006] Malicious attackers further exploit software system vulnerabilities, weak passwords, and improper policy configuration by destroying physical protection measures or exploiting management loopholes, resulting in illegal access to the power wireless private network management system, which in turn causes risks such as leakage of sensitive information and tampering of configuration information
