Abstract
A method and system are provided for improved distributing of a complete software image to all electronic devices of a certain type or model while using encryption to limit its use to specific ones of those devices. In the method, the entire software image is encrypted with a global key and the encrypted software image is distributed to all devices which have the capability of running that software. The global software decryption key for decrypting the software image is uniquely encrypted for every device that is authorized to use the software and the encrypted global software key is distributed to those devices from a field or factory provisioning server across a point-to-point connection.
