The invention relates to an access control onboard system of an aircraft for communication from the open domain (12) to the avionics domain (11), both domains being connected together by a unidirectional link (13) from the avionics domain to the open domain. The system includes: a safety device (10) comprising: access switches (14, 15) to each of the domains, a controller (16), a module for acquisition, buffer storage and transmission to the avionics domain (17), a data control module (18), a module for acquisition from the open domain and for buffer storage (19); and an operator identification means (20).
L' invention concerne un système embarqué de contrôle d'accès, à bord d'un aéronef, pour une communication du domaine ouvert (12) vers le domaine avionique (11), ces deux domaines étant reliés entre eux par une liaison unidirectionnelle (13) du domaine avionique vers le domaine ouvert. Ce système comprend : un dispositif de sécurité (10) comprenant: des commutateurs (14, 15) d'accès à chacun de ces deux domaines, un contrôleur (16), un module d'acquisition, mise en mémoire tampon et transmission au domaine avionique (17), un module de contrôle de données (18), un module d'acquisition depuis le domaine ouvert et de mise en mémoire tampon (19); des moyens d' authentification de l'opérateur (20).
