Abstract
Counterfeiting of optical disc drives used with game systems is prevented by storing an obfuscated authentication key in firmware of the disc drive. Each disc drive can implement a different obfuscation scheme. The authentication key is parsed into components and the components are stored in various locations in firmware of the disc drive. Drive specific software also is stored in the firmware. Remaining locations of the firmware are randomly populated with binary values.
