A Detailed Survey of Fully Homomorphic Encryption Standards to Preserve Privacy over Cloud Communications

The Homomorphic Encryption is a term that denotes a technique of encryption to enable additional computation on cipher texts, this additional computation helps to preserve privacy and provides confidentiality to the payloads those are getting processed between cloud server and clients. The term homomorphic is an indication to the homomorphism term used in Algebra. The term chiefly underlines the fact that homomorphisms between cipher text and plaintext spaces are comparable to the encryption and decryption functions. Homomorphic encryption underscores an additional assessment potential for computation over encrypted data, even without accessing the secret key or decrypting data sets. The results of such a computation continue to be encrypted. This paper gives an account of various homomorphic standards followed in cloud communications and summarizes the key facts and stats of these methods.
