Abstract

Blockchain technology has recently gained significant attention as a potential solution for securing data in cloud computing environments. This is due to its ability to provide a decentralized and immutable ledger of transactions, which can be used to store and manage sensitive information in a secure and transparent manner. In this paper, we propose the use of blockchain-based searchable encryption for improving the security of cloud computing systems. Searchable encryption is a cryptographic technique that allows for searching encrypted data without decrypting it. This allows for more secure storage and retrieval of sensitive information, as the data remains encrypted at all times, even when being searched. By combining searchable encryption with blockchain technology, we can provide a secure and efficient method for storing and searching sensitive data in the cloud. Our proposed system provides several benefits for cloud security. First, it allows for secure storage and retrieval of sensitive data in the cloud, as the data remains encrypted at all times. Second, it allows for efficient searching of encrypted data, making it practical for use in a variety of applications. Third, it provides a decentralized and immutable ledger of transactions, which can be used to provide transparency and accountability for the storage and management of sensitive data. Overall, the proposed system offers a promising approach for improving the security of cloud computing systems using blockchain-based searchable encryption.
