The emergence of new computing paradigms such as cloud computing, the Internet of Things, and the mobile Internet has increased the need for inter-domain access and data sharing, while at present the "centralized" traditional access control technology have showed opaque of access control policy execution, inflexibility of dynamic data management, low-autonomy of resource owners, these shortcomings make it difficult to satisfy the requirements of access control for new computing paradigms with massive, dynamic, and distributed features, an inter-domain access control model based on ABAC model and blockchain interaction is proposed. This paper introduces the technical principle, characteristics and research status of the ABAC model and blockchain, elaborates the model framework, defines the definition of the ABAC model. At the same time, the smart contract in the model is described in detail, and the application in the specific scenario and the specific access control flow are given. Finally, compared with the existing research solution, this model can provide standardized security, convenient, autonomous, and fine-grained access control for inter-domain access.
