Data encryption has been a major tool for ensuring data confidentiality and integrity. Data encryption is mostly applied to data at rest, and data in motion. For data in use, encrypted data is usually decrypted by the user before performing any operation on the data. The security of such data is usually compromised when the user is not trusted. In cloud computing, for instance, where computing services are delegated, decrypting data by a third party before performing any operation is not appropriate. The operation must be performed on the data in its encrypted form; hence, the need for homomorphic encryption. This paper presents the evolution of homomorphic encryption schemes as a basis for research into modern homomorphic encryption schemes. The various stages identified are Privacy homomorphism, Partial homomorphism, Somewhat homomorphism and fully homomorphic encryption.
