Homomorphic encryption-state of the art

Abstract

Homomorphic Encryption has become a viable method for privacy preservation. It basically deals with the computations of encoded data. Homomorphic encryption scheme allows operations on encrypted data which, when decrypted will provide the same results as we performed directly on the raw data. Certain cryptographic algorithms having the homomorphic property. A detailed survey is carried out on the various homomorphic encryption scheme based on the parameter involved, the encryption decryption mechanisms, their hammerphic properties, security considerations etc. The encryption methods with homomorphic property are much suitable for applications require data privacy and security.
