Publication number: 20060149966Abstract: A method and apparatus is provided for authenticating a component (450) for use in a device (100). The device (100) has a predetermined challenge and a predetermined response associated with the predetermined challenge stored in a memory (122). The method detects whether the component (450) has been coupled to the device (100). If the component (450) has been detected (206), the predetermined challenge is provided to the component (208). The device (450) then determines whether a component response has been received from the component within a predetermined response time (210). If a component response is received within the predetermined response time (210), it is compared to the predetermined response (212). The component is disabled (214) if either the component response is not received within the predetermined response time (210) or the component response is received within the predetermined response time (210) but the component response is not equivalent to the predetermined response (212).Type: ApplicationFiled: January 4, 2005Publication date: July 6, 2006Inventors: Ronald Buskey, Larry Puhl, Duane Rabe
