One or more devices transmit, to a user device, an application for secure mobile streaming, and receive, from the user device, a registration request for the application. The registration request includes a user ID and a unique device identifier (UDID) for the user device. The one or more devices initiate a validation procedure for the user ID or UDID. When the user ID or UDID is validated, the one or more devices generate a device-token for the user device. The device-token includes a hash value based on information in the registration request and an expiration date for the device-token. The one or more devices send the device-token to the user device via a private network. The device-token is required to permit the user device to receive a secure content stream via a public network.
