State information that describes the operating conditions or circumstances under which a user intends to operate the system is obtained. In the preferred embodiment of the invention, a valid hash value is determined, preferably based on the state information and preferably by locating the valid hash value within a table of valid hash values indexed by the state information. Candidate authorization information is obtained from the user, and a candidate hash value is generated by applying a hashing algorithm to the candidate authorization information, the state information, or a combination of the candidate authorization information and state information. The candidate hash value and the valid hash value are then compared, and the microprocessor-based system is enabled if the candidate hash value matches the valid hash value. In this manner, the designer or distributor of the system can determine, at the time of manufacture or distribution, the conditions and circumstances under which the system may be operated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for selectively enabling a microprocessor-based system","description":"A system for selectively enabling a microprocessor-based system is disclosed.
