(EN) IMPROVED CERTIFICATE CHAIN VALIDATION
(FR) VALIDATION AMELIOREE D’UNE CHAINE DE CERTIFICATS
Abstract
(EN)
A method of validating an access operation to content on a device, comprising evaluating a license associated with the content, characterized by further evaluating a ruleset applicable to the content and validating the access operation only if the license and the ruleset both permit the access operation. The license may indicate the ruleset. Alternatively the ruleset applicable to the content may be determined by determining a characteristic of the content and selecting the ruleset based on the determined characteristic. The characteristic preferably is one of: a type of the content, a source of the content, a classification of the content. In an embodiment one or more links are evaluated which associate a person and/or the device to an authorized domain and a link associating the ruleset to the authorized domain is evaluated as well. Also a system configured for executing the method.
(FR)
La présente invention concerne un procédé de validation d’une opération d’accès à un contenu sur un dispositif, comprenant l’évaluation d‘une licence associée au contenu, caractérisé par une évaluation complémentaire d’un ensemble de règles applicables au contenu et validant l’opération d'accès seulement si la licence et l'ensemble de règles permettent toutes deux l'opération d'accès. La licence peut indiquer l’ensemble de règles. De façon alternative, l’ensemble de règles applicables au contenu peut être défini par la détermination d'une caractéristique du contenu et la sélection de l’ensemble de règles en fonction de la caractéristique déterminée. La caractéristique est de préférence une de : type du contenu, source du contenu ou classification du contenu. Dans un mode de réalisation, une évaluation d’un ou plusieurs liens associant une personne et/ou le dispositif à un domaine autorisé ainsi que l’évaluation d’un lien associant l’ensemble de règles au domaine autorisé sont réalisées également. La présente invention concerne aussi un système configuré pour exécuter le procédé.
