Multi-user authentication method and system for mobile communication scene and information processing terminal

Abstract

The invention belongs to the technical field of network communication, and discloses a multi-user authentication method and system for a mobile communication scene and an information processing terminal. An initial authentication stage; and switching the authentication stage. According to the method, a multi-user authentication scheme is designed by using an aggregation message authentication code with a detection function and a contribution-based broadcast encryption technology based on MEC and SDN technologies, so that the channel congestion probability is reduced, the calculation overhead and communication overhead of switching authentication are reduced, the switching authentication time delay is reduced, and the safety performance of group authentication is improved. According to the invention, the network architecture integrated by the SDN and the MEC server can monitor the network state in real time according to the dynamic topology of the user in advance to make a switching decision, a large amount of calculation overhead can be completed before switching authentication, and the switching authentication time delay is effectively reduced. And the group messages are aggregated, so that the number of times of signaling interaction can be effectively reduced, and the possibility of channel congestion is reduced.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a multi-user authentication method, system, medium, equipment and information processing terminal in a mobile communication scene. Background technique [0002] At present, with the improvement of the technical standards of the Internet of Things industry and the continuous breakthroughs in key technologies, the connection of a large number of intelligent terminals and other network edge devices is bound to generate a large amount of real-time data. If this type of data processing and analysis is handed over to the cloud, the distance between the cloud and the device will result in high bandwidth consumption and processing delay, which is unacceptable for many delay-sensitive edge-side data. The MEC technology solves such problems to a certain extent by sinking computing, storage, and business service capabilities to the edge of the network, which is of ...

AI Technical Summary

Problems solved by technology

[0006] (1) The standardized identity authentication protocol 5G-AKA defined in the existing 5G network only supports a single user to perform the authentication process independently, which usually requires several rounds of signaling interaction and complex switching key management mechanism, and cannot handle a large number of The case where devices request network services at the same time

[0007] (2) At present, group-oriented authentication and key agreement schemes have been proposed to support multi-user access. However, when these schemes are implemented in actual communication scenarios, there are still some problems in terms of security and performance, and most schemes Inter-domain switching scenarios are not considered
