An Attribute-Based Access Control using Chaincode in RFID Systems

Ideal RFID systems used in product lifecycle should satisfy high confidentiality, anonymity, integrity and high availability. However, collection and distribution of RFID data are subject to various security concerns. RFID middleware systems are likely to suffer from parameter manipulation and eavesdropping, raising privacy concerns. Most recent works focus on access control schemes with models based on Attribute-Based Access Control (ABAC). These schemes, to enhance the security and privacy, are based on centralized models. In this paper, we present an ABAC model using chaincode in RFID systems. Our ABAC system is based on Hyperledger Fabric Blockchain, which is a modular and extensible open-source system for deploying and operating permissioned blockchains. Our ABAC model uses smart contracts and blockchain technology as versatile infrastructures to represent the trust and endorsement relationship that are essential in the ABAC model in order to ensure the security of RFID systems. It should also be noted that the RFID system presented is based on the EPCGlobal standard.
