FIELD: information technology.
SUBSTANCE: system comprises: a security system device (10), having access switches (14, 15), which control access to said two domains, a controller (16), a module (17) for recording, storing data in buffer memory and transmitting data to the avionics domain, a data management module (18), a recording module (19) which receives data from the public domain and stores them in the buffer memory; the system also has an operator identification apparatus (20).
EFFECT: broader functional capabilities of the on-board system for controlling access to an information system on-board an aircraft owing to secure transmission of data from a public domain to an avionics domain, thereby facilitating two-way communication between said two domains.
