Abstract
A method for protection of cloud computing includes homomorphic encryption of data. Partially or fully homomorphic encryption allows for data within the cloud to be processed without decryption. A partially or fully homomorphic encryption is provided. The proposed scheme can be used with both an algebraic and analytical approaches. A cloud service is implemented on a server. A client encrypts data using fully homomorphic encryption and sends it to the server. The cloud server performs computations without decryption of the data and returns the encrypted calculation result to the client. The client decrypts the result, and the result coincides with the result of the same calculation performed on the initial plaintext data.
