Title (EN) METHOD AND SYSTEM FOR IDENTIFYING COMPROMISED NODES
(FR) PROCÉDÉ ET SYSTÈME PERMETTANT D'IDENTIFIER DES NŒUDS COMPROMIS
Abstract:
(EN) The invention relates to a method for identifying compromised nodes in a ZigBee network comprising a general trust center, divided in at least two security domains, each security domain corresponding to a spatial or temporal area, and being associated with a different root keying material, and each node being identified by an identifier, the method comprising: upon detection of a node (Ul) entering into a security domain (SD), the general trust center (TC) distributing to the node at least one keying material share corresponding to the entered security domain, and upon detecting corruption of at least two security domains, determining, for each security domain, based on information registered by the base station (BTS), a respective set of nodes having received keying material corresponding to said security domain, - comparing the respective sets of nodes and identifying the common nodes as being compromised.
(FR) L'invention se rapporte à un procédé permettant d'identifier des nœuds compromis dans un réseau ZigBee comprenant un centre de confiance générale, divisé en au moins deux domaines de sécurité, chaque domaine de sécurité correspondant à une zone spatiale ou temporelle et étant associé à une matière de production de clé racine et chaque nœud étant identifié par un identifiant. Le procédé comprend les étapes suivantes : lors de la détection d'un nœud (U1) entrant dans un domaine de sécurité (SD), le centre de confiance générale (TC) : distribue au nœud au moins une part de matière de production de clé correspondant au domaine de sécurité entré ; lors de la détection d'une corruption d'au moins deux domaines de sécurité, détermine, pour chaque domaine de sécurité, sur la base d'informations enregistrées par la station de base (BTS), un ensemble respectif de nœuds ayant reçu une matière de production de clé correspondant au dit domaine de sécurité ; et compare les ensembles respectifs de nœuds et identifie les nœuds communs comme étant des nœuds compromis.
