The present invention relates to a method of providing secure communication of information between at least a first and second digital audiovisual device (30, 52) and characterised in that the first device (30) communicates to the second device (52) a certificate Ct(KpubT) comprising a transport public key KpubT encrypted by a management private key KpriMan, the second device (52) decrypting the certificate using an equivalent management public key KpubMan and thereafter using the transport public key KpubT to encrypt information sent to the first device, the first device using an equivalent private key KpriT to decrypt the information. The present invention is particularly applicable to a method of providing secure communication between a first and second decoder.

La présente invention concerne un procédé permettant de réaliser des échanges sécurisés d'informations au moins entre un premier et un deuxième appareil audiovisuel (30, 52). En l'occurrence, le premier appareil (30) échange avec le second appareil (52) un certificat "Ct(KpubT)" comprenant une clé publique de transport "KpubT" cryptée par une clé privée de gestion "KpriMan". Le deuxième appareil (52) se sert d'une clé publique de gestion "KpubMan" équivalente pour décrypter le certificat, puis de la clé publique de transport "KpubT" pour crypter l'information envoyée au premier appareil, le premier appareil utilisant une clé privée "KpriT" équivalente pour décrypter l'information. L'invention convient particulièrement aux cas où l'on cherche à assurer des communications sécurisées entre un premier décodeur et un second décodeur.
