A Secured Data Sharing Using Proxy Re-encryption and Blockchain in Cloud Storage
摘要
The development of data sharing in cloud computing has proven valuable. The Paper explores the complexities of ensuring data security within cloud environments and proposes a solution centered around proxy re-encryption. The core objective is to strengthen the security aspects related to sharing data within the scope of cloud computing. The proposed system entails data owners securely archive their encrypted data into cloud storage utilizing identity-based encryption. Authorized users can subsequently access the data through proxy re-encryption. To mitigate resource limitations, an edge device acts as a proxy server to manage computationally intensive tasks. The work leverage information-centric networking to optimize service quality and network bandwidth by delivering cached content through the proxy. The foundational system model relies on blockchain technology, facilitating decentralized data sharing and offering precise access control. A comprehensive security analysis and evaluation of the proposed scheme, illustrate its potential to guarantee data confidentiality, integrity, and overall security Overall, paper presents a holistic strategy to confront data security challenges using proxy re-encryption, edge computing, information-centric networking, and blockchain technology, offering a promising approach for mitigating data security risks in cloud environments.
