Patent AT-E400130-T1: [Translated] METHOD AND SYSTEM FOR CONTROLLING THE SCOPE OF DELEGATION OF AUTHENTICATION DATA

Methods and systems are provided for controlling the scope of delegation of authentication credentials within a network environment. A server (210) is configured to provide a trusted third-party (206) with a ticket authenticating the server, information about a target service (212,214) that a server seeks to access on behalf of the client, and a service ticket associated with the client. This service ticket may be provided by the client (202) or may be a previously granted service ticket granted to the server (210) for itself in the name of the client. The trusted third-party grants a new service ticket to access the target service (212,214) to the server (210), in the client's name, if such delegation is permitted according to delegation constraints associated with the client.
