PROBLEM TO BE SOLVED: To provide an infrastructure for managing the distribution of digital certificates for network security in wireless backhaul networks.SOLUTION: A root certificate management system (root CMS) automatically authenticates surrogate certificate management systems (sur-CMSs), and issues certificate bundles to sur-CMSs that are successfully authenticated. An infrastructure includes a plurality of the sur-CMSs. Each sur-CMS automatically authenticates its own base stations assigned within respective regions, automatically processes certificate requests, and issues certificate bundles to base stations that are successfully authenticated. A certificate bundle issued to a base station includes a digital certificate, signed by the issuing sur-CMS, of a public key of such base station, and at least one further digital certificate including a self-signed certificate of the root CMS.SELECTED DRAWING: Figure 3 |
