A method of transmitting data over a network, from a sending application to a receiving application, including: coding the data, by the sending application, by implementing a predefined rule; detecting alteration of at least one item of data transmitted, by the receiving application, by implementing the predefined rule; and in case an alteration of a data item is detected, restoring the altered data item. In the course of the coding, in the course of the alteration detection, and in the course of the restoration, a cyclic redundancy check or an encryption can be implemented.

Method and device for protecting the integrity of data transmitted over a network

A method monitors at least one avionic system connected to a communication medium that includes at least one active communication switch component. The method includes determining a state of the switch component and evaluating an indicator of a state of the communication medium from the state of the switch component and from a predetermined modeling of communication flows of the communication medium. The method also includes selecting and activating an alarm according to the evaluated state of the communication medium and according to a predetermined modeling of consequences of the evaluated state of the communication medium on a function of the at least one avionic system. A corresponding device and a method for determining conditions for alarm activation are also disclosed.
