Abstract: Data sharing has emerged as one of Internet of Things' most advantageous cloud computing applications as it has developed. Even if the evolution of technology has been visually appealing, data security is still one of its challenges because improper usage of data can result in a variety of negative effects. We provide a proxy re-encryption method in this paper for safe data exchange in cloud contexts. Identity-based encryption enables data owners to outsource their protected information to the cloud, while proxy reset encryption construction allows authorized users to access the data. Due to the limited resources of Internet of Things devices, an edge device serves as an intermediary in order to handle demanding calculations.
Additionally, we successfully distribute cached material in the proxy by using information-centric networking capabilities, hence enhancing the quality of service by making efficient use of the network capacity. Additionally, the foundation of our system concept is blockchain, a ground-breaking technology that permits decentralised data sharing. It achieves very fine regulation of access to data and reduces inefficiencies in centralised systems. The security study along with the assessment of our plan demonstrate the potential of our strategy for guaranteeing data security, confidentiality, and integrity

Keywords: security,integrity, ground breaking technology.
