Abstract: An onboard access control system to an information system onboard an aircraft, for communication from the open domain to the avionics domain, the open end avionics domains being connected to each other through a single-directional link from the avionics domain to the open domain. The system includes: a security device including: access switches controlling access to the avionics and open domains, a controller, a module for acquisition putting data into buffer memory and transmission to the avionics domain, a data control module, an acquisition module from the open domain and putting into buffer memory, and an operator's authentication mechanism.

Abstract: The present invention relates to an on-board aeronautic system intended to be dynamically reconfigured, especially an on-board information system, and to an associated method as well as to an aircraft comprising such a system. In particular, the system comprises a plurality of heterogeneous equipment items, at least part of the said equipment items being reconfigurable, and comprises a reconfiguration management center set up to receive state messages from the said plurality of equipment items and to emit reconfiguration messages destined for the said reconfigurable equipment items as a function of at least the said received messages, the said state messages being emitted according to the same format by monitoring means encompassed in each of the said equipment items, the reconfigurable equipment items encompassing reconfiguration means capable of processing at least one of the said reconfiguration messages in order to reconfigure the said associated equipment item.
