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.

The present invention relates to a securing boot controller for an embedded system, the embedded system further comprising an operational module incorporating an operational function of the system, and a verification module incorporating a function of verifying various components of the system; The controller is configured to:

Securing boot controller for an embedded system, associated embedded system and securing boot method

The present invention relates to a storage method of digital files carried out by a determinist avionic network with predetermined routing. This method comprises a phase (PE) for writing digital files comprising the steps of determining by an end system sending a digital file to be stored, associating a time reference with the digital file to be stored, sending the digital file to be stored with the associated time reference to K separate switches using one or several data frames, generating, via at least some of the switches, a copy of the digital file to be stored and storing this copy in the storage unit of each of these switches with the associated time reference.

Storage method of digital files carried out by a determinist avionic network with predetermined routing, and associated avionic communication system

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.

Mixed avionic communication system of types ARINC 664 P7 and ethernet with predetermined routing

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.
