Inter-part Pairing Information Retention for Authentication Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication technologies in collaborative equipment systems, such as in-vehicle systems, require enhancement for improved fraud prevention and security.
Innovation Solution
A system where equipment communicates using inter-equipment pairing information for mutual authentication, and parts within the equipment use inter-part pairing information, with a mechanism to delete inter-equipment pairing information upon request while maintaining inter-part pairing information, thereby improving authentication security and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inter-equipment pairing information is deleted to improve security after equipment replacement, then fraud prevention is improved, but inter-part pairing information is also deleted causing unnecessary part exchange issues
Solution Approach 1:
The patent segments pairing information into two distinct types: inter-equipment pairing information (for authentication between different equipment) and inter-part pairing information (for authentication between parts within the same equipment). This segmentation allows selective deletion of only inter-equipment pairing information while preserving inter-part pairing information, thus resolving the contradiction between improving fraud prevention and maintaining part exchange flexibility.
2Reliability
If all pairing information is deleted during equipment replacement to ensure security, then authentication security is improved, but processing time increases due to unnecessary part re-pairing
Solution Approach 1:
By segmenting pairing information into inter-equipment and inter-part types, the system can selectively delete only inter-equipment pairing information during equipment replacement. This avoids the time-consuming process of re-pairing parts that were already authenticated, thus reducing processing time while maintaining authentication security.
Solution Approach 2:
The patent extracts and separately manages inter-part pairing information from the general pairing information pool. This extraction allows the system to preserve this critical authentication data during equipment replacement operations, eliminating unnecessary re-pairing processes and reducing overall processing time.
3Device complexity
If inter-part pairing information is deleted to simplify the system, then device complexity is reduced, but authentication between parts becomes vulnerable to spoofing
Solution Approach 1:
The patent segments pairing information management into two distinct processes: one for inter-equipment pairing (which can be simplified) and another for inter-part pairing (which requires enhanced security). This segmentation allows the system to maintain simplified overall structure while implementing robust security specifically where needed for part authentication.
Solution Approach 2:
The patent applies different quality levels of pairing information management to different contexts: inter-equipment pairing uses standard management procedures, while inter-part pairing uses enhanced security measures including protected storage and verification mechanisms. This local quality approach ensures high security for part authentication without unnecessarily complicating the entire system.

AI summary
A system comprising a plurality of pieces of equipment, wherein the equipment included in the system communicates with other equipment by using inter-equipment pairing information, the other equipment being included in the system, and the equipment and the other equipment mutually storing the inter-equipment pairing information, a part included in the equipment communicates with an other part by using inter-part pairing information, the part and the other part being included in the equipment that is identical, and mutually storing the inter-part pairing information, and when receiving a deletion request that is information that requests deletion of the inter-equipment pairing information, the system deletes the inter-equipment pairing information stored in each of the plurality of pieces of equipment, and maintains the inter-part pairing information stored in the part.
