Abstract: The invention relates to an electronic device for the centralized computation and diffusion of the state(s) of an aircraft, configured to at least: calculate the value of one or more aircraft state(s), generate a list of aircraft state(s) the value of which is accessible via the electronic device, the list comprising, for each state, information representative of the said state, diffuse the list to each consumer avionics device, of at least one value of at least one state, receive, from at least one consumer avionics device, at least one request for transmission of one or more values of at least one first state selected from the list, the request comprising the said representative information related to the said at least one first selected state, transmit, to at least one consumer avionics device, only the value or values of the at least one selected state.

Abstract: A method of digitally watermarking a neural network, implemented by an electronic device, the neural network being stored within a data structure including blocks of parameters. The method includes, for a current parameter block consisting of at least N parameters representing real numbers, obtaining a message including N bits, at least N iterations of a parameter modification operation within the current block, including obtaining a current parameter, from among the at least N parameters of the current parameter block, and updating the value of a predetermined index bit of the current parameter as a function of a bit in the message.

Abstract: A method for encoding a digital signature of a neural network, implemented by an electronic device, the neural network being stored within a data structure including blocks of parameters. The method includes, for a current block of parameters including at least M parameters representing real numbers: an operation of acquiring a signature binary image from the digital signature including a set of bits extracted from parameters of the current block of parameters, and an operation of combining the signature binary image with a reference binary image delivering a coded binary image.
