A Resource-Blockchain Framework for Safeguarding IoT

Privacy concerning resource discovery and selection on the Internet of Things (IoT) platform has emerged as a crucial challenge due to constrained network environment, poor throughput, and access control system in the Resource Directory (RD), which could potentially lead to information breaches among intelligent devices. Blockchain is indeed the latest technological model for global information management, point-to-point exchange, consensus process, asymmetric authentication, cognitive agreement, and perhaps other computing innovations to address the challenge. Considering these advantages, a resource-blockchain framework for safeguarding IoT is proposed in this article. The framework facilitates efficient access of information among devices, gathers information about the constrained environment, accepts data from heterogeneous resources and stores them on CoAP-based RD. Moreover, it provides secure transactions and records authorised user’s information via Blockchain-based centralised server which acts as the frontend of CoAP based REST, dispatcher or repository and proxy server. The study demonstrates that Blockchain technologies help in strengthening privacy capabilities and safeguarding intelligent devices.
