Cloud Security Enhancement Using Modified Enhanced Homomorphic Cryptosystem

Cloud computing provides organizations with cost-effective, scalable, and flexible computing resources, enabling them to store, process and manage large amounts of data more efficiently. having instant access to computational resources without having to purchase pricey hardware and software, makes cloud computing an attractive option for businesses of all sizes. The increased use of cloud computing has also led to an increased need for security measures to protect sensitive data stored and processed in the cloud. Without proper security measures in place, cloud computing can be a risky and vulnerable environment, making cloud security a top priority for organizations utilizing cloud services. Homomorphic encryption is among the recent cryptographic technique which is proposed in our work that enables computations that can be done on encrypted data without having to first decrypt it. This makes it possible to securely process sensitive data in the cloud, preserving the privacy and confidentiality of the data. In this research, fully homomorphic encryption is used to implement cloud security for data analytics. We use homomorphic encryption, which enables the processing of the data requiring decryption. The result analysis shows improvement in key generation time, encryption time complexity, and decryption time complexity.
