A COMPARATIVE STUDY ON HOMOMORPHIC ENCRYPTION ALGORITHMS FOR DATA SECURITY IN CLOUD ENVIRONMENT

Data Security in cloud is the prime prerequisite due to the fact of digital violations/ cybercrimes, hacking and attacks are the common words we hear in day to day digital sectors mainly like banking, healthcare, etc. Nowadays, data is been stored in cloud for easy access and retrieval and the privacy preserving is the biggest challenge in cloud. Henceforth, sensitive data is to be safeguarded before storing it to cloud by encrypting, one among the strongest and secured is homomorphic encryption technique where the operations is on the scrambled information where the computation is been carried out without knowing the actual data and easy to connect in any framework by utilizing different open key algorithms. In this paper, the primary concentrate is on open key cryptographic algorithms in view of homomorphic encryption conspire for protecting security. The contextual investigation on different standards and properties of homomorphic encryption is given as the analyzing proof.
