Distributed Authentication Processing Using Split Device Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems performing cooperative operations between devices face challenges in ensuring secure authentication, as they often rely on common information that can be intercepted, leading to potential spoofing and security breaches.
Innovation Solution
A processing device and system architecture that transmits a first request with first information and a second request with different second information to multiple devices, allowing each device to perform calculations and authentication based on unique information, thereby enhancing security by preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If common information is used for authentication between devices, then authentication can be performed, but the system becomes vulnerable to spoofing and security breaches
Solution Approach 1:
The patent divides the authentication information into multiple separate components (first information and second information) that are transmitted through different devices. Each device performs calculation using its own unique information, and the authentication result is determined by combining these separate components. This segmentation prevents any single device from having access to all authentication information, thereby preventing spoofing while maintaining reliable authentication.
2Reliability
If multiple devices are involved in the authentication process, then security is enhanced through distributed verification, but the system complexity increases
Solution Approach 1:
The patent employs a universal calculation function that can be executed by multiple different devices (first device, second device, third device). Each device performs the same type of calculation operation using its own unique information. This multi-functionality approach allows the system to enhance security through distributed verification while maintaining relatively simple device structures, as each device only needs to implement the standard calculation function rather than complex proprietary algorithms.

AI summary
To provide a structure capable of performing more secure authentication between devices.There is provided a processing device comprising: a processing unit that executes a defined process that is defined in advance according to an input first request, executes calculation using first information included in the first request, and transmits a first response including a result of the calculation to a first device having output the first request, wherein the processing unit transmits a second request including second information different from the first information to at least one second device different from the first device, and acquires a second response including a result of calculation using the second information from the at least one second device.
