Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current WiMAX network technologies lack a method for performing anchor authenticator relocation without re-authentication, which is necessary in certain scenarios but not implemented effectively.
Innovation Solution
An anchor authenticator relocation method and system that allows relocation of the anchor authenticator from an old authenticator to a new authenticator without re-authentication, involving steps such as verification by the AAA server and confirmation of the new authenticator's trustworthiness by the old authenticator, ensuring secure and efficient relocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If anchor authenticator relocation is performed without re-authentication, then network management efficiency is improved and unnecessary authentication processes are reduced, but security verification reliability may be compromised
Solution Approach 1:
The system performs preliminary security verification by the AAA server before allowing authenticator relocation without re-authentication. The AAA server verifies the new authenticator's trustworthiness in advance by checking security parameters and credentials, ensuring that the relocation can proceed safely without requiring full re-authentication of the MS, thus improving network management efficiency while maintaining security reliability
Solution Approach 2:
The AAA server acts as an intermediary that mediates the authenticator relocation process. It verifies the new authenticator on behalf of the system, providing centralized security verification. This intermediary mechanism allows the old authenticator to relocate to the new authenticator without direct re-authentication between the MS and new authenticator, maintaining security while improving operational efficiency
2Reliability
If the AAA server verifies the new authenticator and the old authenticator confirms trustworthiness, then security is maintained during relocation, but the relocation process complexity increases
Solution Approach 1:
The security verification process is segmented into distinct responsibilities: the AAA server handles verification of the new authenticator's credentials and trustworthiness, while the old authenticator handles confirmation of the new authenticator's validity. This segmentation allows each component to perform its specific security function without duplicating verification steps, maintaining security while managing complexity through clear division of labor
Solution Approach 2:
The system implements feedback mechanisms where the AAA server provides verification results to the old authenticator, and the old authenticator confirms whether the new authenticator is trusted. This feedback loop ensures that security requirements are met while providing clear decision points in the relocation process, making the complexity manageable through structured information flow and decision-making

AI summary
The disclosure provides an anchor authenticator relocation method and system. The method includes: after an old authenticator accepts an anchor authenticator relocation request of a Mobile Station (MS), a new authenticator sends an authenticator relocation request to an AAA server; when the AAA server's verification on the new authenticator is passed and the old authenticator confirms that the new authenticator is trusted, the anchor authenticator is relocated to the new authenticator. The disclosure provides a detailed solution to perform anchor authenticator relocation without re-authentication.
