SYSTEM AND METHOD FOR DYNAMICALLY MANAGING BADGE ACCESS

摘要

A method executed in a badge, a badge reader, and a server for controlling access to different zones. The badge obtains from the badge reader an invitation to request access to a zone Zout. The badge ascertains that the badge is authorized to access the zone Zout. The badge has a current badge identifier ID. The badge retrieves a zone-associated badge identifier IDout associated with the zone Zout. The badge issues to the badge reader a request for access to the zone Zout. The request includes: the current badge identifier ID, the zone-associated badge identifier IDout; and a current badge key K. The badge receives from the badge reader either an authorization to access the zone Zout during a specified period of time Tout or a refusal to grant access to the zone Zout. The server implements the distribution of keys used by the badge reader and badge.
