Handheld Scanner for Electronic Component Cryptographic Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of an efficient method for enterprises to verify whether electronic components in electronic devices are authorized, as unauthorized components can be substituted during manufacturing or shipping, posing security risks such as data breaches or remote control vulnerabilities.
Innovation Solution
A handheld scanner is used to individually verify electronic components by sending inputs through their I/O interfaces, performing cryptographic operations, and determining authorization based on the received outputs, allowing for quick identification of authorized components without needing to attach to other components on the circuit board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional verification methods are used to check electronic components, then security risks can be identified, but the verification process is time-consuming and inefficient
Solution Approach 1:
The patent embeds cryptographic authentication mechanisms and unique identifiers directly into electronic components during manufacturing. This preliminary action enables rapid verification by the handheld scanner without time-consuming traditional inspection methods, resolving the contradiction between verification accuracy and time consumption
Solution Approach 2:
The patent replaces traditional manual or mechanical verification methods with a cryptographic-based electronic authentication system. The handheld scanner uses cryptographic operations to verify component authenticity, substituting slow mechanical inspection with fast electronic verification that maintains high reliability while dramatically reducing verification time
2Reliability
If cryptographic verification is performed by attaching the scanner to other components on the circuit board, then authorization can be determined, but the verification process becomes complex and time-consuming
Solution Approach 1:
The patent extracts the cryptographic verification capability directly to the handheld scanner, eliminating the need to attach it to other components on the circuit board. The scanner independently performs cryptographic operations to determine component authorization, simplifying the verification process while maintaining accurate authorization determination
Solution Approach 2:
The patent introduces a standalone handheld scanner as an intermediary device that mediates the verification process. Instead of components interacting complexly with each other, the scanner acts as an independent intermediary that performs cryptographic verification, reducing system complexity while ensuring reliable authorization determination
3Quantity of substance
If unauthorized electronic components are used in electronic devices, then cost can be reduced, but security vulnerabilities such as data breaches and remote control issues arise
Solution Approach 1:
The patent implements preliminary anti-action by embedding cryptographic authentication mechanisms in authorized components and using the handheld scanner to verify authenticity before devices are deployed. This prevents unauthorized components from being installed, countering the temptation to use cheaper unauthorized parts while eliminating security risks
Solution Approach 2:
The patent establishes a feedback mechanism where the handheld scanner provides immediate verification results about component authorization. This feedback loop enables enterprises to identify and remove unauthorized components, preventing security vulnerabilities while maintaining cost efficiency by avoiding the hidden costs of security breaches

AI summary
In some examples, a scanner that is to verify a device includes a scanner input/output (I/O) interface to physically and communicatively connect to a device I/O interface of the device. The scanner includes a processor to send an input through the scanner I/O interface to the device, receive, at the scanner I/O interface, an output responsive to the input from the device, the output comprising a cryptographic value based on a cryptographic operation applied on data of the input, and determine whether the device is an authorized device based on the received output.
