BLOCKCHAIN-BASED APPROACH TO SECURE DATA SHARING IN THE INTERNET OF THINGS ENVIRONMENT

ABSTRACT

The evolution of the Internet of Things (IoT) has seen data sharing as one of its most useful applications in cloud computing. As eye-catching as this technology has been, data security remains one of the obstacles it faces since the wrongful use of data leads to several damages. This work proposes a Proxy Re-Encryption (PRE) approach to secure data sharing in cloud environments. Data owners can outsource their encrypted data to the cloud using Identity-Based Encryption (IBE), while proxy re-encryption construction will grant legitimate users access to the data. With the Internet of Things devices being resource-constrained, an edge device acts as a proxy server to handle intensive computations. Also, we make use of the features of Information-Centric Networking (ICN) to deliver cached content in the proxy effectively, thus improving the quality of service and making good use of the network bandwidth. Further, our system model is based on blockchain, a disruptive technology that enables decentralization in data sharing. It mitigates the bottlenecks in centralized systems and achieves fine grained access control to data.
