Zusammenfassung:A system and method for developing a software program containing sensitive information requires the use of a developer key (a unique public/private key pair) to download the software onto a uniquely identified developer chip. The software program can then be developed and debugged on the developer chip. After being developed and debugged, the software program is transferred to a uniquely identified release chip for subsequent use. Specifically, transfer of the software program requires use of a release key (also a public/private key pair) that is different from the developer key. The private key part of the developer key, as well as all developer chips (albeit a limited number) are protected by strict security procedures.
