Title (EN) COMMUNICATION METHOD AND APPARATUS FOR AN INDUSTRIAL CONTROL SYSTEM
(FR) PROCÉDÉ ET APPAREIL DE COMMUNICATION POUR UN SYSTÈME DE COMMANDE DE PROCESSUS INDUSTRIELS
Abstract:
(EN) A communication method 100 for an industrial control system (ICS) is disclosed. The communication method 100 includes the step of receiving network packets that are being sent to an address in the ICS. The network packets carry critical payloads 1000 and non-critical payloads 1100. The communication method 100 further includes selectively capturing a critical network packet 1000. The critical network packet 1000 is identified based on a predefined list of critical payloads capable of controlling a physical state of the ICS. The communication method 100 further includes generating a signature Sigk{p} 1300 from the critical network packet 1000 using a signing algorithm and transmitting a combined network packet 1200 that includes the critical network packet 1000 and the signature to the address. The communication method 100 further includes receiving the combined network packet 1200 at the address, and verifying the integrity of the critical network packet 1000 by authenticating the signature 1300 using a verification algorithm.
(FR) L'invention concerne également un procédé de communication pour un système de commande de processus industriels (ICS). Le procédé de communication comprend l'étape consistant à recevoir des paquets de réseau qui sont envoyés à une adresse dans les ICS. Les paquets de réseau transportent des charges utiles critiques (1000) et des charges utiles non critiques (1100). Le procédé de communication (100) consiste en outre à capturer de manière sélective un paquet de réseau critique (1000). Le paquet de réseau critique (1000) est identifié sur la base d'une liste prédéfinie de charges utiles critiques pouvant commander un état physique des ICS. Le procédé de communication (100) consiste en outre à générer une signature Sig k {p} à partir du paquet de réseau critique (1000) à l'aide d'un algorithme de signature et à transmettre un paquet de réseau (1200) combiné qui comprend le paquet de réseau critique (1000) et la signature à l'adresse. Le procédé de communication (100) consiste en outre à recevoir le paquet de réseau (1200) combiné à l'adresse, et à vérifier l'intégrité du paquet de réseau critique (1000) par authentification de la signature (1300) à l'aide d'un algorithme de vérification.
