Abstract
Disclosed are systems and methods for protecting secret device keys, such as High-bandwidth Digital Content Protection (HDCP) device keys. Instead of storing secret device keys in the plain, a security algorithm and one or more protection keys are stored on the device. The security algorithm is applied to the secret device keys and the one or more protection keys to produce encrypted secret device keys. The encrypted secret device keys are then stored either on chip or off-chip.
