Title
(EN) ELECTRONIC BOARD PROVIDED WITH SECURITY FUNCTIONS AND METHOD FOR ENSURING ELECTRONIC BOARD SECURITY
(FR) CARTE ELECTRONIQUE DOTEE DE FONCTIONS SECURITAIRES ET PROCEDE DE SECURISATION DE LA CARTE ELECTRONIQUE
Abstract
(EN)
In order to prevent sensitive signals interception between electronic circuits (2.2, 2.3) on an electronic board (2.1), these circuits are positioned in a secure zone in such a way that they are no more than a predetermined distance apart. The circuits in the secure zone include at least a control circuit (2.2). The electronic board also includes a further zone defining a non-secure environment in which the spacing constraint does not apply to the circuits (2.4) therein. Communication between the circuits in the secure zone and the non-secure environment takes place via a communication circuit (2.5) which either lets through or bars the electrical signals. The flow of electrical signals through the communication circuit is controlled by an electrical control signal (2.6) from the control circuit. The invention also concerns a method for locking the control circuit when the electrical status of the signal flow control signal does not match the status applied by the control circuit.

Pour eviter de pouvoir capter des signaux sensibles entre des circuits electroniques (2.2, 2.3) places sur un carte electronique (2.1), ces circuits sont disposes dans une zone securisee de maniere a ne pas etre eloignes les uns des autres de plus d'une distance determinee. Les circuits de Ia zone securisee comprennent au minimum un circuit de contrδle (2.2). La carte electronique comporte egalement une autre zone definissant un environnement non securise, les circuits (2.4) de cette zone n'ont pas besoin de respecter Ia contrainte de distance. La communication entre les circuits de Ia zone securisee et de 1 ' environnement non securise s'effectue a travers un circuit de communication (2.5) laissant passer ou non les signaux electriques. Le passage des signaux electriques dans Ie circuit de communication etant conditionne par un signal electrique de commande (2.6) emis par Ie circuit de contrδle. L' invention concerne egalement un procede permettant de bloquer Ie circuit de contrδle si l'etat electrique du signal commandant Ie passage des signaux ne correspond pas a l'etat impose par Ie circuit de contrδle.
