A Robust Remote User Authentication Scheme for Supply Chain Management Using Blockchain Technology

For a company's product life cycle to be faster, more efficient, and more effective, supply chain management (SCM) is critical. Nevertheless, present SCM systems must be improved to ensure genuine products and transactions are private and secure. As a result, this study proposes a safe SCM system depending upon blockchain and the Internet of Things to ensure that the products are genuine. All SCM stakeholders can initiate an encrypted, secure transaction for their goods or services due to the Quick Response (QR) scanner that works with the Internet of Things (IoT) and the blockchain-integrated distributed system. Finally, a genuine product from the manufacturer will be sent to the customer. To make authentication quicker and easier for scattered IoT devices, a lightweight asymmetric key encryption mechanism known as Diffie-Hellman key exchange and Hyperledger Fabric-based blockchain technology with on-chain smart contracts are deployed. The service provider registers each SCM stakeholder and provides them with their own public and private keys, which will be used to authenticate participants and IoT devices. Examining security and scalability shows that the recommended solution is more trustworthy and secure than existing methods.
