Abstract
A method and encryption node () for providing encryption of a message m according to a selected encryption scheme. A set of k noise factors are pre-compiled () from random numbers and predefined integer parameters of the selected encryption scheme by the encryption node () in advance. The k noise factors are saved () to be used for encrypting the message m when later requested () by a client (). A subset of/noise factors are then selected () out of the pre-computed set of k noise factors and used as input to the encryption scheme when encrypting () the message m by computing a cipher text c which is delivered () as an encrypted message, e.g. to the client (). Thereby, less time needs to be spent for computing the necessary noise factors after receiving the encryption request and higher throughput can thus be achieved for messages to be encrypted. In particular, the solution may be used to increase the throughput for a stream of messages.
