Lightweight security 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 suitable for 5G network equipment and an application,comprising the following steps: selecting a large prime number, respectively selecting three variables for all registered SNs, registered UEs and registered MDs, and selecting two secure hash functions to realize system setting; completing service network registration and equipment registration for different entities; realizing access authentication and key agreement of a single UE; and realizingmass MD group access authentication and key agreement. According to the invention, the signaling cost, the communication cost and the storage cost are reduced, signaling overhead can be effectively reduced, and signaling conflicts can be avoided; in the LSAA protocol for massive MDs, the SN can complete the authentication of a group of MDs by directly verifying the aggregated message verificationcode, thereby effectively reducing the communication and calculation overhead. Extended Chebyshev chaotic mapping is used, each MD can securely negotiate a different session key with the SN and consume less overhead.

Description

technical field [0001] The invention belongs to the technical field of communication network security, and in particular relates to a lightweight security access authentication method and application suitable for 5G network equipment. Background technique [0002] At present, the closest existing technology: by 2020, the fifth generation (5G) mobile communication system will enter the stage of full commercial use. New mobile service applications such as mobile interactive games, virtual reality (VR) and full-line graphics will be incorporated into the technical requirements of 5G systems. In addition, the industry and academia are also working hard to expand the scope of 5G applications from the current human communication to wider fields, such as human-machine collaborative communication, ultra-dense access to the Internet of Things (IoT), in-vehicle networks, and new industrial information. Since 2016, the 3GPP committee has been developing 5G standards with the goal of u...

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
