Blockchain Based Key Exchange Mechanism for Cloud Storage

Abstract

A cloud storage system is a system that saves information for an individual or company. The cloud system enables the owner of data to control and share his or her information with specific users. Because of the irrevocable consequences of inaccurate information, the integrity or interfere resistance characteristic is critical for cloud systems. Owing to its immutability and irreversibility, blockchain technology has emerged as a viable solution. Unfortunately, significant technological hurdles remain, such as limited storage, privacy concerns, irrevocable permission, poor performance, and high energy usage. The goal of this study is to address these blockchain disadvantages and offer a blockchain-based cloud storage paradigm. To ensure tamper resistance, the suggested model is designed with blockchain technology. To protect privacy, the master-key exchange method and other cryptographic approaches are used. Perfectly fine and dynamic access control, consent that may be revoked, integrity, and fraud resistance are all features of the proposed paradigm. A thorough security study demonstrates that this proposed paradigm is prove that its secure in terms of confidentiality and fraud resistance. The performance study reveals that this research methodology outperforms the existing technique in the literature in terms of overall performance.
