Enabling Efficient Deduplication and Secure Decentralized Public Auditing for Cloud Storage

What is it about?

Public auditing and data deduplication are integral considerations in providing efficient and secure cloud storage services. Speciically, we employ the idea of redactability for blockchain to handle often neglected security issues that would adversely afect the integrity of stored auditing records on blockchain in decentralized auditing models.

Why is it important?

This work introduces a blockchain-based secure decentralized public auditing in a decentralized cloud storage with an efficient deduplication model to design a feasible secure cloud storage model. The main objectives of this work as follows; 1. We prioritize the primary objective of decentralized public auditing in terms of scalability, efficiency, and security trade-offs by analyzing the redactable blockchain based auditing paradigm from constantly integrative approaches, which eliminates the centralized TPA and resists the malicious TPA. 2. We mainly highlight a new challenge that is unique in the blockchain-based auditing model framework. The challenge would threaten the integrity of audit-trails storage over blockchain in the rational paradigm.
