Blockchain-Enabled Access Management System for Edge Computing

In the post-cloud era, edge computing is a new paradigm with data processed at of network, which can process close to end-user in real time and offload cloud task intelligently. Meanwhile, decentralization, tamper-proof anonymity blockchain technology provide trusted environment for computing. However, it does raise considerable concerns security, privacy, fault-tolerance so on. For example, identity authentication access control rely on third parties, heterogeneous devices different vendors IoT, leading security privacy risks, etc. How combine advantages two has become highlight academic research, especially issue secure resource management. Comprehensive involve all aspects platform, data, application control. In. this paper, architecture behavior an Access Management System (AMS) proof concept (PoC) prototype are proposed Color Petri Net (CPN) model. The domains organically connected by interfaces interactions. simulation operation, activity role association proves feasibility effectiveness AMS. instances platform business control, database services, IOT hub service run Advantech WISE-PaaS through User Account Authentication (UAA). Finally, fine-grained distributed be realized help attribute. Namely, smart contracts used register, broadcast, revoke authorization, as well create specific transactions define policies.
