Fully Homomorphic Encryption is used to increase the security of untrusted systems and applications that deal with sensitive data. Homomorphic encryption is a kind of encryption that enables computation to be performed on encrypted data without the need for decryption. When data is stored in the public cloud, homomorphic encryption is utilized to prevent it from being shared inside the cloud service. The encryption technique employed in Partially Homomorphic Encryption may execute either an additive or a multiplicative operation, but not both at the same time. In the case of Fully Homomorphic Encryption, on the other hand, both methods may be accomplished at the same time. In this paper, we first illustrate the challenge of transforming algorithms that can function on unencrypted or regular data to algorithms that can work on encrypted data. In this work, we show that, although FHE provides the ability to do any computations, its full usefulness can only be realized if they allow the execution of arbitrary algorithms over encrypted data. This model uses it to conduct FHE operations on encrypted data using the Enhanced Data Encryption Technique, and the encrypted data is utilized to perform sorting operations.
