Abstract

The invention relates to a method and a device for secret radio communications, using one or more radio links and one or more free-space optical links A device of the invention comprises a key generator (12), a transmitting set for transmission via power distribution lines (13), dedicated electrical conductors (21), a differential circuit-breaker (22), a power-line filter (23), several sources of modulated light (31), a first mobile radio system (40) comprising a radio device B (41) and a 'legitimate receiver for optical transmission' (42), and a second mobile radio system (50) comprising a radio device C (51) and a 'legitimate receiver for optical transmission' (52). Thanks to the free-space optical transmission, secret keys are distributed and changed automatically every 10 seconds. The first mobile radio system (40) and the second mobile radio system (50) can therefore establish a radio link encrypted using these secret keys.
