ONBOARD ACCESS CONTROL SYSTEM FOR COMMUNICATION FROM THE OPEN DOMAIN TO THE AVIONICS DOMAIN

摘要

An onboard access control system to an informationsystem onboard an aircraft, for communication from theopen domain to the avionics domain, the open end avionicsdomains being connected to each other through asingle-directional link from the avionics domain to the opendomain. The system includes: a security device including:access switches controlling access to the avionics andopen domains, a controller, a module for acquisitionputting data into buffer memory and transmission to theavionics domain, a data control module, an acquisitionmodule from the open domain and putting into buffermemory, and an operator's authentication mechanism.
