Research on Software Supply Chain Security Assurance Mechanism System Based on Blockchain Technology

This research introduces a security assurance mechanism for the software supply chain, leveraging blockchain technology to address existing vulnerabilities within the supply chain. The inherent decentralized and tamper-resistant features of blockchain offer robust safeguards for data exchanges across various stages of the supply chain. The system incorporates an enhanced Byzantine fault-tolerance algorithm to improve the network's resilience, ensuring that supply chain nodes can maintain efficient operation even in complex and challenging environments. For critical security aspects within the supply chain, specialized algorithms and models have been devised, and the system's security and performance are validated through simulation models. The simulation outcomes demonstrate that the system exhibits strong resilience against attacks and potential threats to the software supply chain, while also maintaining high operational efficiency alongside its security measures. Data analysis reveals that the implementation of this security assurance mechanism significantly elevates the overall safety and stability of the software supply chain. The findings of this study provide a theoretical foundation and technical framework for enhancing security assurance capabilities in software supply chains.
