ABSTRACT:
A method and apparatus for protecting software used in an electronic system. An electronic key is associated with the software, which is at least partially unreadable unless modified. The electronic system using the software to be protected receives the electronic key, and reads the software to determine that the electronic key and software are associated. The system then modifies the software to render it readable and identifies the software with the electronic system by storing an identifier of the system with the software. Finally, the system modifies the electronic key to render it useless.
