Blockchain-Based Distributed Data Security and trust management System for Cloud Computing

Abstract

Cloud computing is rapidly being used in many facets of the IT business since it has emerged as a crucial technology for meeting infrastructure and data service demands at lower costs, with less effort, and with more scalability. Despite the rapid growth of cloud computing, data security remains a significant challenge that has yet to be fully resolved. This ongoing concern hampers the development of cloud services. In a landscape utilizing distributed ledger technology and service-oriented architecture, blockchain emerges as a promising decentralized solution. The main security problem, however, is key leakage, which makes it simple for outsiders to access guarded data.

This research presents the Blockchain-based Proof of Staking with Elliptic Curve Encryption (BPECE) technique, designed to enhance the security of data transfers in the cloud. To address potential vulnerabilities, it employs the Policy-based Key Authentication (PBKA) algorithm, which efficiently verifies the authenticity of each node in the network. This approach aims to provide a robust solution for securing cloud data transactions. The suggested method creates a public key for every document. In comparison to earlier ways, the suggested solution provides improved security performance.
