An electronic device for monitoring at least one avionics software application capable of being executed on a platform hosting an operating system offering services,

Method and electronic device for monitoring an avionics software application via system call(s) counters, related computer program and avionics system

Disclosed is method for monitoring an avionics software application, able to be executed on a platform including resources and hosting an operating system, the platform being intended to be on board an aircraft, implemented by an electronic monitoring device. The method includes: implementing at least one monitoring operation of the application from among syntactic monitoring of each call emitted by the application to the operating system; semantic monitoring of each call emitted by the application to the operating system; monitoring of a dynamic of the calls emitted by the application to the operating system; and monitoring of the use by the application of the resources of the platform; and generating an alarm signal if an abnormal behavior of the application is detected.

Method and electronic device for monitoring an avionics software application, related computer program and avionics system

This electronic device for receiving data via a redundant communication network including at least two independent elementary networks, is configured to be connected to each elementary network, including a receiving module configured to receive, via the redundant communication network, at least one data frame, each frame including a frame identifier and a data field, each frame being transmitted over each of the elementary networks; and a verification module configured, for at least one received frame identifier, to calculate a frame check code for each of the elementary networks, then to compare the frame check codes between the elementary networks, each frame check code depending on the data field of the frame received via the respective elementary network.
