Token-Based Tamper Detection Apparatus Using Secured Copies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security systems face inefficiencies in detecting tampering, particularly in token-based access control systems, where verifying the integrity of tokens representing user, device, and network information is cumbersome and time-consuming.
Innovation Solution
An apparatus that stores secured copies of hard, network, and resource tokens, allowing for rapid comparison with received tokens to detect tampering by identifying mismatches, thereby facilitating faster and more efficient tampering detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional token verification methods are used, then security verification is performed, but the detection process is cumbersome and time-consuming
Solution Approach 1:
The system pre-generates and stores expected token values (hard token, network token, resource token) in the security system before actual verification occurs. When verification is needed, the system simply compares the received token against the pre-stored expected value, eliminating the need for complex real-time verification computations and significantly reducing verification time while maintaining high detection accuracy
2Reliability
If comprehensive token verification is performed, then tamper detection capability is improved, but system complexity increases
Solution Approach 1:
The verification system is segmented into three independent token verification components: hard token verification, network token verification, and resource token verification. Each token type has its own pre-stored expected value and verification logic. This segmentation allows the system to verify multiple tokens independently and efficiently without requiring a single complex verification mechanism, thereby improving comprehensive tamper detection while managing system complexity through modular design

AI summary
According to one embodiment, an apparatus may store: a hard token representing identification information of the device, a network token representing the status of a network, and a resource token representing information associated with a resource. The apparatus may further store secured copies of the hard token, network token, and resource token. The apparatus may receive a suspect token indicating a risk that at least one of the device, the network, and the resource has been tampered, and in response, determine to inspect at least one of the hard token, network token, and resource token. The apparatus may then compare the at least one of the hard token, network token, and resource token with its corresponding secured copy. If at least one of those tokens does not match its corresponding secured copy, the apparatus may communicate a revalidation token indicating at least one token has been tampered.
