Achieving A Secure Cloud Storage Mechanism Using Blockchain Technology

Abstract—Storage requirements are increasing rapidly with fast-growing Cloud computing technology. The more data storage and transaction processing requirements, the more chances of malicious activities. Storage security is a vital concern nowadays. To deal with this problem, in this research, we propose a system that provides an efficient security mechanism for data storage on the Cloud with enhanced access control policies by using Blockchain technology, which is immutable in nature. The usage of smart contracts improves transparency and creates a trust model that eliminates the requirement of a trusted third party. The system manages the log trails of all transactions and accomplishes all access policies. The proposed model is transparent, traceable, and secure. Data owners hold all rights to their data and any activity pertaining to accessing the data illegitimately shall not be accepted by the network and shall be notified to all the concerns. We demonstrate our proposed mechanism with details about all concerned stakeholders. The Attribute-Based Encryption (ABE) scheme is used with multiple authorities to manage the user attributes that avoid the use of the central authority. The smart contract avoids the computational burden on the user side and reduces communication costs. We analyze security and compare the performance of our proposed model.

Index Terms—Cloud storage, data sharing, blockchain, smart contract, access control, attribute-based encryption, integrity
