    摘要： A vehicle accesses a configuration database to determine whether a reconfiguration function is authorized. The reconfiguration function may involve, for example, installing the component in the vehicle, removing the component from the vehicle, replacing the component with another component in the vehicle, replacing another component in the vehicle with the component, modifying the component, upgrading the component and rendering the component operable. Upon determining that the reconfiguration function is authorized, the vehicle allows the reconfiguration function to be performed. The reconfiguration function may be authorized based on a type of the vehicle, a type of the component or a combination of configuration elements in a current configuration of the vehicle.

    摘要： A redundant processing system includes a pair of processors, each processor having an error detector, a key generator, and a lock circuit. The error detectors sense the outputs generated by their processors and generate an error signal when defective data is sensed. The key generators develop multi-bit codes of known patterns that are disrupted in response to receipt of an error signal from an error detector. The codes generated by the key generators are supplied to lock circuits which produce the same known multi-bit codes, and which compare their own codes to the codes supplied by the key generators. If a mis-match is detected, it will be due to a disrupted code that resulted from an error signal. Data from the processor associated with the error signal is rejected.

    摘要： Authentication is performed to a confidence level (CL) desired by a verifier (220). A prover (210) picks and sends certain same size, square matrices to the verifier (220). A random request bit is sent (234) from the verifier (220) to the prover (210) after the receipt of a certain square matrix. Depending on the request bit, calculations are made (244, 264) by the verifier (220) to determine if the matrices sent from the prover are verifiable. The prover (210) is iteratively authenticated by the verifier (220). Iterations are continued until (320) a count of the iterations (IL) reaches a number sufficient to achieve the desired confidence level (CL). After a delay, more iterations can achieve a higher confidence level by building on previous result of authentication without having to begin at zero. During this delay, the verifier (220) can perform tasks in reliance on the result of authentication. Digital logic can perform the authentication.

    摘要： A vehicle authenticates a prospective component for use in the vehicle by obtaining from a certification authority a certification that an authentic component is associated with a cryptographic key. The vehicle obtains the certification separately from the component. The certification certifies that the cryptographic key is bound to information identifying the authentic component. The vehicle utilizes the cryptographic key obtained from the certification authority in cryptographic communication with the prospective component, and determines whether the prospective component is the authentic component based on whether the cryptographic key is successfully utilized in the cryptographic communication.

    摘要： A vehicle authenticates a component class of a prospective component for use in the vehicle by obtaining from a certification authority a certification that an authentic component of the component class is associated with a second cryptographic key. The certification certifies that the second cryptographic key is bound to information identifying an authentic component of the component class. The vehicle utilizes the second cryptographic key obtained from the certification authority in cryptographic communication with the prospective component, and determines whether the prospective component is an authentic component of the component class based on whether the second cryptographic key is successfully utilized in the cryptographic communication.
