摘要： An authenticating circuit includes a first and second challenge vector input, a first and second highly variable process-dependent circuit and a logic circuit. The first highly variable process-dependent circuit receives a first vector from the first challenge vector input and generates a first output that is a function of the first vector and at least one process-dependent feature of a component of the first highly variable process-dependent circuit. The second highly variable process-dependent circuit receives a second vector from the second challenge vector input and generates a second output that is a function of the second vector and at least one process-dependent feature of a component of the second highly variable process-dependent circuit. The logic circuit generates a response output that is a function of the first output and the second output. The function operates so that the response output is independent of environmental conditions of the authenticating circuit.
