Abstract
A method for securely provisioning a device for operation within a service provider infrastructure over an open network comprises the device establishing physical and data link layer network connections for communication on at least a subnet of the open network and obtaining a network configuration data such as an IP address and a subnet mask from a provisioning server that responds to a network configuration broadcast request. A device establishes a secure hypertext transport protocol connection to a first provisioning server that corresponds to one of: i) and IP address and port number; and ii) a fully qualified domain name stored in a non-volatile memory of the device. After mutual authentication, the first provisioning server provides at least one of: i) a configuration file; and ii) identification of a second provisioning server and a cipher key through the secure connection. If the first provisioning server provided identification of a second provisioning server, the device establishes a transport connection to the identified second provisioning server. The second provisioning server provides an encrypted file which, when decrypted using the cipher key yields the configuratio…
