Abstract
A transmitting device (100) generates a message (102). The message has a message length (104) and comprises message data (106). A key input (108) is identified, and a message authentication key (112) is derived based on the key input and the message length. Based on the message authentication key and the message data, a message authentication code (118) is derived, which is used to authenticate the message.
