Abstract:
1. A system for selectively enabling a microprocessor-based system, comprising: circuitry for obtaining state information describing at least one microprocessor-based system operating condition; circuitry for determining at least one valid hash value, the at least one valid hash value to based on the state information; circuitry for obtaining candidate authorization information from a user of said microprocessor-based system; circuitry for generating a candidate hash value by applying a hashing algorithm to at least one of: said candidate authorization information, and said state information; circuitry for comparing said candidate hash value and said at least one valid hash value; and circuitry for causing said microprocessor-based system to enter a terminal shut down state if comparing said candidate hash value and said at least one valid hash value fails to match to enable said at least one microprocessor-based system to operate based on the one or more predetermined system operating conditions.
