Abstract
(EN)
The invention relates to a method for measuring the reputation of paths (C1; C2; C3) taking nodes (N1, N2, N3, N4, N5, N6) in a communication network (R) and comprising, for each node taken by a common path of the network: a) assigning a security score (SDS1, SDS2, SDS4, SDS5, SDS6) to said node; b) estimating a first confidence index (I1) using: - a sum on the current path of the successive scores of the nodes taken by the current path; and - a number of nodes taken by the current path, the estimate of the first confidence index giving a measurement of the reputation of the current path.
(FR)
Il est décrit un procédé de mesure de réputation de chemins (C1; C2; C3) empruntant des nœuds (N1, N2, N3, N4, N5, N6) dans un réseau de communication (R) et comportant, pour chaque nœud emprunté par un chemin courant du réseau : a) une affectation d'un score de sécurité (SDS1, SDS2, SDS4, SDS5, SDS6) de ce nœud; b) une estimation d'un premier indice de confiance (I1) à partir de : - un cumul sur ledit chemin courant des scores successifs des nœuds empruntés par le chemin courant; et - un nombre de nœuds empruntés par le chemin courant, l'estimation dudit premier indice de confiance donnant une mesure de réputation du chemin courant.
