Abstract

ABSTRACT Data sharing has been identified as one of the Internet of Thingsmost useful uses in cloud computing. Data security continues to be one of the challenges this technology has, even though it has been visually appealing, as improper usage of data results in a number of negative effects. We suggest a proxy re-encryption strategy to protect data sharing in cloud contexts in this study. Data owners can utilize identity-based encryption to outsource their encrypted data to the cloud, while proxy re-encryption construction will enable legitimate users access to the data. Due to the limited resources of Internet of Things devices, an edge device operates as a proxy server to conduct demanding computations. Furthermore, we use information-centric networking features to effectively deliver cached content in the proxy, thereby improving performance making efficient use of the network capacity and raising the quality of the service. Our system concept is also built on the blockchain, a ground-breaking technology that enables decentralized data sharing. It accomplishes fine-grained data access control while reducing bottlenecks in centralized systems. The results of our plan's security analysis and evaluation demonstrate its potential for maintaining the security, confidentiality, and integrity of data.
