This comprehensive survey explores homomorphic encryption methods for data security in cloud services, indicating their importance for secure computation.
The tendency of having accessibility to information anytime and anywhere has contributed to individuals or organizations shifting from the storage of information to Internet-based cloud services. This shift has made data more vulnerable as data in the cloud cannot be operated on unless the computation is outsourced to a third-party which can be compromised. Furthermore, in order to keep data secure and accessible securely, homomorphic encryption techniques can be used. Homomorphic encryption supports computation on ciphertexts without decryption first. This paper gives a comprehensive survey of homomorphic encryption.
