Understanding integer-based fully homomorphic encryption.

As there is a continuous growth of big data, the researchers are showing interest in the applications of cloud computing concerning privacy, and security. On the other hand, many researchers and the experts of cybersecurity have commenced on a quest for improving the data encryption methods. Clients or data owners are more interested to outsource their data on commercial public clouds for more flexibility, security, confidentiality and to reduce economic investments. Under this circumstance, homomorphic encryption appears as a probable solution, in which the information of the client is encrypted on the cloud in such a process that it can allow computation on data without decryption. The main intent of this paper is to present the systematic review of research papers published in the pitch of integer-based fully homomorphic encryption. The performance measures and contributions are also analyzed. Furthermore, different platforms used for implementation, and the diverse platforms used for performing the FHE are also studied. Finally, it highlights the challenges and gaps to be addressed in modeling and learning about competent, effectual, and vigorous FHE for the cloud sector and pays attention to directions for better future research.
