| Abstract(in English) | This paper investigates the critical access control issue of the Internet of Things (IoT) to prevent unauthorized access to IoT resources, e.g., data and devices. More specifically, this paper considers the smart contract functionality of the emerging Ethereum blockchain to propose a novel Attribute-Based Access Control (ABAC) framework for distributed and fine-grained IoT access control. The framework consists of one Policy Management Contract (PMC), one Subject Attribute Management Contract (SAMC), one Object Attribute Management Contract (OAMC) and one Access Control Contract (ACC). The PMC, SAMC and OAMC are responsible for storing and managing access control policies (i.e., statements claiming who can access what under what conditions), attributes of subjects (i.e., entities accessing resources) and attributes of objects (i.e., resources being accessed), respectively. The ACC retrieves the corresponding policy, subject attributes and object attributes from the PMC, SAMC and OAMC respectively to perform the ABAC, when receiving access requests from a subject. To show the feasibility of the proposed framework, we construct a local private Ethereum blockchain system and implement the four smart contracts on the blockchain. |
