Terminal Capability Reporting for Anti-Pseudo Base Station Key Agreement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems fail to inform network nodes of a terminal's anti-pseudo base station capacity, preventing effective authentication and key agreement processes, thereby increasing the risk of network attacks from pseudo base stations.
Innovation Solution
A method and device for reporting anti-pseudo base station capacity indication information from the terminal to the communication device, enabling authentication and key agreement processes that match the capacities of both the terminal and the target base station, using predetermined key systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-pseudo base station key assignment is implemented to protect communication messages, then communication security is improved, but the system cannot perform authentication and key agreement matching terminal capacity because network nodes are not informed of terminal capacity
Solution Approach 1:
The patent segments the capacity indication into specific types (first capacity indication information for first anti-pseudo base station key, second capacity indication information for second anti-pseudo base station key), allowing the terminal to report different capacity levels to different network nodes. This enables targeted key assignment matching terminal capabilities while maintaining security.
Solution Approach 2:
The patent introduces capacity indication information as an intermediary element that bridges the terminal and network nodes. This intermediary carries capacity information from the terminal to the network, enabling the network to perform appropriate authentication and key agreement processes without directly querying terminal capabilities.
2Adaptability or versatility
If capacity indication information is transmitted to enable matched authentication, then authentication adaptability is improved, but information transmission overhead increases
Solution Approach 1:
The patent changes the parameter representation by using compact capacity indication information that encodes terminal capabilities in a standardized format. Instead of transmitting detailed capability descriptions, the system uses parameterized indication values that can represent multiple capacity levels efficiently.
Solution Approach 2:
The capacity indication information serves multiple functions: it identifies terminal capacity level, determines appropriate authentication method, and selects matching key assignment procedures. This multi-functionality reduces the need for separate signaling messages for each capability aspect.

AI summary
Provided are a method and device for reporting a capacity, a method and device for key agreement, a terminal and a communication device and system. The terminal sends anti-pseudo base station capacity indication information to the communication device, wherein the anti-pseudo base station capacity indication information can indicate an anti-pseudo base station capacity of the terminal to the communication device. The communication device can determine the anti-pseudo base station capacity of the terminal after acquiring the anti-pseudo base station capacity indication information sent by the terminal, and perform an authentication and key agreement process matching the anti-pseudo base station capacity of the terminal and an anti-pseudo base station capacity of a target base station, so as to negotiate an anti-pseudo base station key matching the anti-pseudo base station capacities of the terminal and the target base station for against the pseudo base station during communication therebetween, thereby reducing a risk of a network attack from a pseudo base station, improving communication safety between the terminal and the base station and enhancing user experience.
