Abstract
A method and encryption node (300) for providing encryption of a message m according to a selected encryption scheme. A noise computation engine (300a) in the encryption node (300) computes (3:1) 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 (3:3) from a client (302) for encryption, an encryption engine (300b) in the encryption node (300), encrypts (3:4) the message m by computing a cipher text c as e=gm·F mod n2, where g is another predefined integer parameter of the selected encryption scheme. The cipher text c is then delivered (3:5) as an encryption of the message m, e.g. to the client (302) or to a cloud of processing resources (304).
