Abstract
Game software for use in video game systems can be downloaded from Internet servers to game consoles in encrypted form to protect the software from being copied by software pirates. A small but essential part of the game software can be encrypted for use with a larger amount software that is not encrypted. The encrypted portion is downloaded into a secure cryptoprocessor preferably in a memory cartridge that plugs into a game system. This cryptoprocessor decrypts the downloaded software, stores it in on-chip EEPROM and then executes it, all in the same cryptoprocessor. The non-encrypted software is processed in the game system by a conventional processor which depends on data generated by program instructions decrypted and executed in the secure cryptoprocessor.
