The evolution of the Internet of Things has seen data sharing as one of its most useful applications in cloud computing. As eye-catching this technology remains one of the obstacles as it faces since the misuse of data leads to several damages. In this work, a proxy re-encryption approach is proposed to secure data sharing in cloud environments. Data owners can outsource their encrypted data to the cloud using identity-based encryption, 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, the features of information-centric networking to deliver cached content in the proxy are used. Thus improving the quality of service and making good use of the network bandwidth. Further, the proposed work 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. The security analysis and evaluation of this scheme show the promise of proposed approach in ensuring data confidentiality, integrity, and security.
