Abstract

A processor (301) for encrypting a signal to be communicated from a first location to a second location or for decrypting a signal which has been communicated from a first location to a second location, the processor being operable to send or receive a signal which comprises a sequence (400) of frames including an initial full synchronisation frame (401) followed by consecutive mixed frames (402) each of which includes a partial frame portion (PT) of encrypted traffic information together with a partial frame portion (PS) of synchronisation information.
