Abstract: The present invention relates to an avionic communication system that comprises a plurality of switches and a plurality of equipment units.Each equipment unit is capable of generating digital data that are present in the form of a plurality of frames of the first type that are in compliance with a first protocol, or of the second type that are in compliance with a second protocol. Each switch and each receiving equipment unit are configured so as to determine the type of each frame received and, as a function of the determined type, to process this frame in accordance with the corresponding protocol, each frame of the first type being processed on a prioritised basis in relation to each frame of the second type. The first protocol is of the type ARINC 664 P7 and the second protocol is of the type Ethernet with predetermined routing.

Abstract: The present invention relates to a switch including a plurality of input ports, a plurality of output ports, at least one output port, called observation port, being connected to an observation module able to analyze the traffic of the frames passing through via the switch, and a conveying component configured to convey each frame.The switch is configured to transmit, to the observation modules via the observation port, only frames according to a first observation condition and a second observation condition, The compliance of a frame with the first observation condition is determined as a function of an observation field and the compliance with the second observation condition is determined as a function of the identifier and/or of an input and/or output port associated with this frame.

Abstract: An avionics communication gateway including a module for acquiring at least one data message, each message being according to a communication protocol and including a header and a payload including a plurality of successive fields, a module for filtering each acquired message, validating the message if it complies with a set of filter criteria, and blocking it otherwise, and a module for transmitting, to a corresponding recipient, each validated message. The filter module includes a unit for generating a main table for each message, representing a tree of the fields of the payload of the message according to a set of levels related to the communication protocol, and a unit for calculating, for each message, a dictionary table and at least one auxiliary table from among first, second and third auxiliary tables, the filter module using the at least one auxiliary table for filtering the message.

Abstract: A method of integrity control, an allocation of virtual identifier, to each stream, only known to each transmitter or receiver, located at one end of the stream, a transmission by a transmitter at the end of a stream, of a message including the payload, the value of a counter of transmitted messages, and a transmission aggregate determined from the virtual identifier known to the transmitter, the value, the payload, the reception by a receiver, at the other end of the stream, of the message, and determination of a reception aggregate from the virtual identifier known to the receiver, the value received, the payload received, the end-to-end integrity check by comparing transmission and reception aggregates.

Abstract: A method implemented by an onboard avionics computer for executing a plurality of binary codes that are associated with a plurality of sets of metadata, wherein: the plurality of binary codes and the plurality of metadata are hierarchized into a number of levels at least equal to two; a first binary code, of a level, is associated with a first set of metadata of the level, and a second binary code of a lower level, itself associated with a second set of metadata of the lower level; the first set of metadata comprises a data signature, the data comprising at least a first message digest associated with the first binary code, and the second set of metadata comprises a public key; the method comprising the execution, by the second binary code, of the following steps: applying a hash function to obtain a second message digest of the first binary code; decrypting the signature using the public key to obtain the first message digest; authorizing the execution of the binary code, if and only if the first message digest is identical to the second.
