A Blockchain-Inspired Attribute-Based Zero-Trust Access Control Model for IoT

The connected or smart environment is the integration of devices (sensors, IoT devices, actuator) into Internet Things (IoT) paradigm, in which a large number are connected, monitoring physical and processes transmitting centralized database for advanced analytics analysis. This integrated setup allows greater levels automation systems than possible with just Internet. While delivering services to different application within systems, these perform an impeccably device-to-device communications that allow them access selected subsets device information data. sensitive private nature data renders infrastructure vulnerable copious attacks threat agents exploit cyberattacks not only affect critical but probably bring people’s lives. Hence, measures need be taken securing environments, such as dynamic control, network screening, behavioural anomalies. In this paper, we have discussed essential cyberthreats vulnerabilities environments proposed ZAIB (Zero-Trust ABAC using Blockchain), novel secure framework monitors facilitates access-controlled mechanisms based on environmental parameters behaviour. It protected by zero-trust architecture provides analysis calculating trust each request. enforces variable policies specifically generated scenario attribute-based control (ABAC). We used blockchain ensure anonymous user registrations immutable activity logs. All attributes, level histories, IPFS. Finally, security evaluation shows satisfies needs active defence end-to-end enforcement data, users, involved grid network.
