Homomorphic encryption is an innovative cryptographic mechanism that allows performing cryptographic operations even on encoded data without intermediate decoding. As a result, sensitive information cannot be compromised in case of dealing with outsourcing services. This article firstly provides the general background of HE and most notably discusses the types of HE such as partial homomorphic encryption, somewhat homomorphic encryption, and fully homomorphic encryption Each of these types has its advantages on drawbacks depending on the type of operations and the level of computation efficiency. The paper also considers research undertaken recently oriented towards increasing the feasibility of HE by all means, especially the lowering of the costs in computation. A comparative analysis matrix contains distinctive features of various approaches in HE and defines their complexity, security, and usability concerns. This and further surveys present the HE history and its above- and below-the-line progress and suggest paths for HE-morphed developmental works for applications such as cloud computing and machine learning that are inherently privacy-preserving.
