Lightweight secure access authentication method and application suitable for 5G network equipment

Abstract

The invention belongs to the technical field of communication network security, and discloses a lightweight security access authentication method and application suitable for 5G network equipment. A large prime number is selected to select three prime numbers for all registered SNs, registered UEs and registered MDs respectively. One variable, select two secure hash functions to realize system settings; complete service network registration and device registration for different entities; access authentication and key negotiation of a single UE; mass MD group access authentication and key negotiation. The invention reduces signaling cost, communication cost and storage cost. It can effectively reduce signaling overhead and avoid signaling conflicts; in the LSAA protocol for massive MDs, the SN can complete the authentication of a group of MDs by directly verifying the aggregation message verification code, effectively reducing communication and computing overhead. Using the extended Chebyshev chaotic map, each MD can securely negotiate a different session key with the SN with less overhead.

Description

Technical field [0001] The present invention belongs to the communication network security technology, and more particularly to a lightweight safety access authentication method suitable for 5G network equipment. Background technique [0002] Currently, the closest prior art: By 2020, the fifth generation (5G) mobile communication system will enter a comprehensive commercial phase. New mobile service applications such as mobile interactive games, virtual reality (VR) and full-line images will be included in the technical requirements of the 5G system. In addition, the industry and academia are also working to extend the range of 5G applications from current personnel to a broader field, such as human-machine collaborative communication, super-intensive access network (IoT), in-vehicle network and new industrial information. Since 2016, the 3GPP Committee has been developing 5G standards, and its goal is to broadly bandwidth, high capacity, high-density site and high reliability t...

AI Technical Summary

Problems solved by technology

[0005] (1) The existing standard AKA mechanism and existing related protocols have man-in-the-middle attacks, redirection attacks, DoS attacks, identity privacy leaks, and consume a lot of computing overhead and communication overhead

[0006] (2) The current 3GPP standard lacks a large-scale device authentication mechanism, and the simultaneous execution of the standard AKA protocol by a large number of devices will cause serious signaling congestion

[0007] The difficulty of solving the above technical problems: develop a new access authentication protocol to overcome the above loopholes and realize the authentication and key agreement between the network and ordinary UEs and large-scale MDs, which has strong security and consumes reasonable cost
