Homomorphic Encryption between Client and Cloud Server

A cloud server is a web-based service that may be accessed from anywhere in the world. The absence of security and privacy on the cloud server is a concern, and to remedy it, a more secure technique must be offered. The encryption between the client and the cloud server has been clarified in this paper, and accounts request processing on encrypted data utilizing this method without the requirement for a secret key. Partial type encryption, as well as schemes, are terms used to describe this sort of encryption (Paillier and RSA). These systems allow a person to double or double their performance if they have access to the encrypted data and information relevant to the encrypted task. The alternative option is to encrypt all of the data, although this is more difficult, but it is difficult for the programmer to do this alone, but it requires a team of specialists.
