Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturers face challenges in preventing the cloning of electronic components, as existing methods fail to ensure authenticity and prevent unauthorized use or extended lifespan of OEM products.
Innovation Solution
Integration of a secure hardware device with electronic components using public key infrastructure (PKI) techniques, including a Trusted Platform Module (TPM), to verify the authenticity of components and limit their usage through digital signatures and key management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional authentication methods are used, then device complexity is low, but reliability of preventing cloning is insufficient
Solution Approach 1:
The patent introduces a secure platform as an intermediary component between the processor and external environment. This secure platform contains a cryptographic module that generates and manages key pairs, acting as a mediator that provides cryptographic functions without requiring the main processor to handle complex security operations directly, thus improving reliability while controlling complexity.
Solution Approach 2:
The system is segmented into distinct functional components: a main processor for general operations and a separate secure platform for cryptographic operations. This segmentation allows the authentication functionality to be isolated in a dedicated secure module, improving the reliability of authentication while keeping the overall system architecture manageable through clear separation of concerns.
2Object-affected harmful factors
If simple authentication methods are used, then ease of operation is high, but ability to prevent unauthorized use is insufficient
Solution Approach 1:
The secure platform performs self-service by automatically generating key pairs and managing cryptographic operations without requiring external intervention or complex user procedures. The authentication process is automated through digital signatures and verification, eliminating the need for manual authentication steps while providing strong cloning prevention through cryptographic security.
3Reliability
If digital signature verification is implemented, then reliability of authenticity verification is improved, but device complexity increases
Solution Approach 1:
The cryptographic module is merged with the secure platform, combining key generation, digital signature creation, and verification capabilities into a single integrated security subsystem. This merging approach improves authentication accuracy by ensuring all cryptographic operations occur within a trusted boundary, while the integrated design manages complexity through unified resource management and shared security protocols.

AI summary
An electronic component includes a processor and a memory. The electronic component has a secure platform capable of storing at least one dual key pair and a corresponding digital signature. There is also a system including a host machine and an electronic component capable of being operated by the host machine. The electronic component has a processor, a memory, and a secure platform capable of storing at least one dual key pair and a corresponding digital signature. Another aspect describes a method, which includes reading a public key from an electronic component by a host machine, verifying the public key against a stored key in the host machine, digitally signing data using a private key from the electronic component, verifying the signed data against the stored key, and using the electronic component by the host machine only if the signed data and the public key are verified.
