Abstract[English]
The invention describes a method of providing cyber security enhancement, the use of a hardware circuit for providing cyber security enhancement and a system for providing cyber security enhancement, in each case in particular by obfuscating a signal processing. The Method for example comprises the steps of - receiving an input signal via a first hardware sub-circuit of a hardware circuit and processing the received input signal into at least one of a first processed signal according to a first type of processing and a second processed signal according to a second type of processing being different to the first type of processing, - deriving from only from one of the first processed signal and/or second processed signal a first output signal, - transmitting the first output signal to a second hardware sub-circuit of the hardware circuit, - detecting from which of the first processed signal and/or second processed signal the transmitted first output signal is derived from and processing the transmitted first output signal into a second output signal in dependency from result of the detection.[French]
L'invention concerne un procédé de fourniture d'amélioration de la cybersécurité, l'utilisation d'un circuit matériel destiné à fournir une amélioration de la cybersécurité et un système destiné à fournir une amélioration de la cybersécurité, dans chaque cas, en particulier par l'obscurcissement d'un traitement de signaux. Le procédé comprend par exemple les étapes consistant à recevoir un signal d'entrée par l'intermédiaire d'un premier sous-circuit matériel d'un circuit matériel et à traiter le signal d'entrée reçu en au moins l'un d'un premier signal traité selon un premier type de traitement et un second signal traité selon un second type de traitement étant différent du premier type de traitement, à déduire un premier signal de sortie uniquement à partir de l'un du premier signal traité et/ou du second signal traité, à transmettre le premier signal de sortie à un second sous-circuit matériel du circuit matériel, à détecter à partir duquel du premier signal traité et/ou du second signal traité le premier signal de sortie transmis est dérivé et à traiter le premier signal de sortie transmis en un second signal de sortie en fonction du résultat de la détection.
