Abstract
A method and encryption node () for providing encryption of a message m according to a selected encryption scheme. A noise computation engine () in the encryption node () computes () a noise factor F as a function of a predefined integer parameter n of the selected encryption scheme and a random number r. When the message m is received () from a client () for encryption, an encryption engine () in the encryption node (), encrypts () the message m by computing a cipher text c as e=g·F mod n, where g is another predefined integer parameter of the selected encryption scheme. The cipher text c is then delivered () as an encryption of the message m, e.g. to the client () or to a cloud of processing resources ().
