Abstract
The transmission of signed messages occurs between a transmitter (1) and a receiver (3) connected by a transmission line system (2). The transmitter (1) and the receiver (3) respectively comprise a coding device 7 and a decoding device 11. Means 4 situated at the transmitter supply a signature SG as a function of the message M which is to be transmitted. The message associated with its signature, as well as a common key E, are transmitted by the transmitter towards the receiver after coding by means of an intrinsic key R.sub.1. Upon being received, the message M linked with its signature SG is decoded by means of an intrinsic key R.sub.2 determined at the receiver location in such manner as to establish equality between intrinsic keys R.sub.1 and R.sub.2.
