According to the method, a first communication device (1), such as an RFID reader, authenticates a second communication device (3), such as an RFID tag, by using an asymmetric authentication protocol based on a generated a session key. The tag authenticates the reader by using a symmetric communication protocol based on a generated other session key. At least a portion of the session key is used to generate the other session key.
