IoT security verification framework based on 5G network slice and service method thereof

Abstract

The invention provides an IoT security verification framework based on a 5G network slice and a service method thereof. Under this frame, the Internet of Things architecture comprises user equipment,an access network, a core network and an Internet of Things server, the user equipment is divided into different network slices according to different required service types and then accessed to the core network through the access network, and is connected with a data network and communicated with the Internet of Things server. A privacy protection slice selection mechanism is introduced, so thatthe fog node is allowed to select a proper network slice to carry out data forwarding, and the access service type of a user is hidden. In addition, service-oriented anonymous authentication and key agreement are realized, and the anonymity and authenticity of the user and the confidentiality of service data are ensured. Based on the framework, a user can carry out anonymous authentication on an Internet of Things server based on authorization of a 5G core network and the Internet of Things server and construct a security data channel so as to access service data cached on local fog and maintained on a remote Internet of Things server.

Description

technical field [0001] The invention relates to an Internet of Things framework and service method based on 5G network slicing that supports verification and belongs to the technical field of wireless communication. Background technique [0002] The introduction of network slicing and fog computing by 5G communication technology brings various unique advantages to customized services in IoT, but they also cause considerable problems in terms of security and privacy protection. First, both IoT services and 5G infrastructure (specific fog nodes) face serious threats to privacy, integrity, availability, and authentication, such as eavesdropping attacks, impersonation attacks, tracking attacks, and tampering attacks. Second, it is difficult to ensure that users access 5G networks and IoT services with authentic information. For example, some users will pretend to be legitimate users to access the core network and enjoy IoT services without charging. In addition, IoT service pr...

[0002] The introduction of network slicing and fog computing by 5G communication technology brings various unique advantages to customized services in IoT, but they also raise considerable issues in terms of security and privacy protection

[0003] Existing 5G network security verification mechanisms based on 5G network slice architecture generally focus on the strategy of slice selection, while ignoring the service-oriented authentication using network slices to establish secure communication between user equipment and IoT servers in 5G networks

In addition, the existing secure communication protocol is based on the machine type communication (MTC) security network certification in the 4G / LTE network architecture, which cannot meet the bandwidth, QoS and security requirements of 5G-IoT large-scale machine type communication. The security protection of network slice selection needs to be considered based on the network slice architecture
