Secure Distributed Cloud Storage based on the Blockchain Technology and Smart Contracts

Objectives: This paper addresses the problem of secure data storage and sharing over cloud infrastructures. A secure, distributed structure incorporating blockchain is proposed that supports confidentiality, integrity, availability. Methods/Analysis: The combines two well-known technologies: one them Ethereum Blockchain its Smart Contracts other RSA encryption authentication scheme. used as a structure, which ensures availability integrity while provides sensitive confidentiality source authentication. Findings: As result, users can trust it be certain they securely exchange information through publicly accessible shared storage. application either user interface (UI) or command-line (CLI). Novelty /Improvement:The novelty this work system could for on well file verification. Also, are already offered by system. Doi: 10.28991/ESJ-2023-07-02-012 Full Text: PDF
