This disclosure is directed to a dynamic certification system. In general, a device may transmit a request message to a cloud spectrum broker/licensed shared access (CSB/LSA) controller requesting certification for operation in shared wireless spectrum. The device may then receive a response message containing information on available certifications for operating in the shared wireless spectrum. If at least one available certification is determined to be usable by the device, then, depending on the system configuration, the device may claim an available certification (e.g., by obtaining an electronic certification document, token, etc.) or may request to use an available certificate, which may be confirmed by the CSB/LSA controller. The device may then operate in the shared wireless spectrum based on conditions set forth in the certificate.
