Abstract:
A method implemented in a network element for controlling access to a set of resources on a per-application basis, the set of resources including subsets of the resources where each subset is accessible to a set of one or more applications through the use of a separate group key, the method comprising the steps of receiving an authentication request from a node communicatively connected to the network element through a first network interface of the network element, the authentication request including a certificate for the node, validating the certificate for the node, determining that the certificate has been authorized for the set of one or more applications through a query of a certificate database, retrieving each group key that corresponds to the set of one or more applications through a query of a group key database, and returning each group key retrieved from the group key database to the node.
