Root-of-Trust Circuit for Unauthorized Server Relocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server systems lack effective mechanisms to ensure information security by verifying the integrity and location of the server, particularly in cases of theft or unauthorized relocation, which can lead to breaches of confidential information.
Innovation Solution
Implementing a root of trust (ROT) circuit that obtains position information, verifies it against authorized locations, and controls server functions based on the verification result to prevent unauthorized access and maintain security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the server is relocated to different locations, then the adaptability and versatility of the server are improved, but the information security and confidentiality protection are compromised
Solution Approach 1:
The patent applies preliminary action by pre-configuring authorized location information in the ROT circuit before the server operates. The ROT circuit stores cryptographic credentials and authorized location data in advance, enabling automatic verification when the server is relocated. This preliminary setup allows the server to maintain security protocols while adapting to different authorized locations without requiring manual security reconfiguration.
Solution Approach 2:
The ROT circuit serves as an intermediary between the server's relocation capability and the security management system. It mediates by verifying location information through cryptographic protocols and controlling whether the server can access sensitive functions based on verification results. This intermediary layer enables location adaptability while maintaining security through automated verification and control mechanisms.
2Reliability
If the ROT circuit verifies position information and controls server functions, then the information security is improved, but the device complexity increases
Solution Approach 1:
The ROT circuit is designed as a multi-functional security module that combines key storage, cryptographic verification, location validation, and function control capabilities in a single integrated component. This universal approach consolidates multiple security functions into one device, reducing overall system complexity while maintaining comprehensive security verification for server relocation scenarios.
Solution Approach 2:
The ROT circuit implements self-service by autonomously verifying position information and controlling server functions without requiring external intervention. It automatically compares current location against authorized locations, makes security decisions based on verification results, and enforces access controls independently. This self-service capability reduces the complexity of external security management infrastructure.

AI summary
An information security management method, a secure management circuit, and a server are provided. In the method, first position information is obtained through a root of trust (ROT) circuit. The first position information is verified through the ROT circuit to generate a first verification result of the first position information. One or more functions operated by a main processor are controlled through the ROT circuit according to the first verification result. Accordingly, the information security capability can be enhanced.
