Abstract

A method of authenticating a message (111) received via a transmission channel (108) using a Message Authentication Code (MAC). The message comprises a message body (114) and a tag (116) and the method comprises the steps of generating a second tag (115) according to a MAC function (112) on the basis of the received message body and a secret key (113), calculating a distance (117) between the received tag and generated second tag, and comparing (118) the calculated distance with a predetermined threshold value
