Patent

CA 2479789

A method and apparatus are disclosed which incorporate a system for enabling the adaptive modification of the security level of a node in a network. The system is particularly applicable to dynamic network i.e. networks in which nodes may be mobile and in which the network topology is not constant. The node receives beacon signals from other nodes in the network, said signals providing an indication of the alert level of the other nodes and an indication of whether the other nodes are trusted members of the network. The alert level of the node is determined based on the received signals.

L'invention concerne un procédé et un dispositif incorporant un système destiné à permettre la modification adaptative du niveau de sécurité d'un noeud dans un réseau. Ledit système est particulièrement destiné à des réseaux dynamiques, c.-à-d. des réseaux dans lesquels les noeuds peuvent être mobiles et la topologie réseau n'est pas constante. Le noeud reçoit des signaux de balise provenant d'autres noeuds du réseau, lesdits signaux donnant une indication du niveau d'alerte des autres noeuds et indiquant si les autres noeuds sont des éléments de confiance du réseau. Le niveau d'alerte du noeud est déterminé sur la base des signaux reçus.
