Research on Traceability Encryption of Auto Parts Based on Blockchain and IBE

To address the issues of sensitive data encryption and high complexity in tracing automobile components within the traceability system, an encryption scheme tailored for such systems is proposed. This solution leverages the distributed nature of blockchain technology to provide a reliable access control mechanism for the traceability system. Moreover, it integrates identity-based encryption (IBE) to efficiently and securely encrypt data. By combining smart contracts with access control policies, precise authorization management can be achieved, ensuring that each participant can access and utilize system data only within their authorized scope. This significantly enhances the security and credibility of automobile component traceability systems.
