Quantum Cloud Computing in Multi-Cloud Environments for Safe Data Transfer Using Two-Tier Homomorphic Encryption

Nowadays, data transfer has been vast online and on social media. Hence data security in the various cloud environments has been enabled to send and receive data. While transferring the data, some issues in the cloud environment are the lack of connectivity, control, and the insecurity of the password and the data. To handle this problem, data security and the internet connection have to be enabled for the cloud environments. The method of homomorphic encryption and the transport layer security protocol have been enabled for the analysis. The homomorphic encryption method converts the data to the ciphertext for making the text in the original format. Then the transport layer security protocol is used to authenticate the data, and the data integrity of the communication can be executed. The proposed system performs better than current protocols like Dynamic Level Based Integrity Checking Protocol, TLS protocol, and Lightweight Cryptosystem, making it a potential option for jobs involving safe and effective cloud information processing. Overall, the proposed Two-tier Homomorphic Encryption system exhibits improved execution time, security strength, resource utilization, communication overhead, and user satisfaction. It addresses issues such as connectivity gaps, control deficiencies, and password and data insecurity, making it an effective method for boosting cloud security in quantum cloud computing environments.
