Abstract
A service platform/transceiver device locking system include a transceiver device that disables its data communication operations during an initialization operation and generates challenge information, and a platform device that retrieves that challenge information. The platform device uses a service platform private key to encrypt the challenge information, and provides the encrypted challenge information and a service-platform-provider-private-key-signed service platform public key to the transceiver device. The transceiver device uses a service platform provider public key to verify a service platform public key in the service-platform-provider-private-key-signed service platform public key to produce a verified service platform public key that it uses to decrypt the encrypted challenge information to produce decrypted challenge information. If the transceiver device determines that the decrypted challenge information matches the challenge information, it enables its data communication operations and locks itself to operate with a service platform associated with the service platform public key.
