Prototype Traceability Blockchain for Security-Regulated Industries

By recording the transactions and events of all relevant parties on the blockchain, the industrial blockchain can realize the data traceability and tracking of the whole process, thus helping enterprises to realize the supply chain management, production process management, and quality control of the whole chain. Nevertheless, with the widespread deployment of industrial blockchain provenance, many security issues have emerged, such as centralized registration authority and potential distributed denial-of-service (DDoS) attacks. These existing issues threaten the usability of industrial blockchain traceability(IBT). This paper mainly studies some identity authentication problems that still exist in industrial blockchain traceability. Combining blockchain, elliptic curve cryptography, dynamic link-out mechanism, and batch verification, a reliable and efficient logistics information and utility center authentication protocol is proposed. Experimental results show that the proposed protocol achieves improvements in security and performance compared to other related schemes.
