ABSTRACT:
After a processor-controlled system having communications capabilities is delivered to a user in its generic configuration, customization of the system is realized in accordance with the invention by downloading thereto selected information objects, e.g., software components and/or data, from a server. To avoid unauthorized downloading of the selected information objects, certain information in a request for the objects by the system to the server is encrypted and/or cryptographically signed. Such information may be, e.g., a serial number identifying the system. If the server succeeds in decrypting the encrypted information and/or authenticating the digital signature, and thereby verifies the identity and legitimacy of the system, the server downloads the selected information objects to realize the customization.
