Abstract
Determining authenticity of a component in an imaging device includes generating an analog signal as an authentication challenge to the component. The component then generates a response to the authentication challenge by converting the analog signal into one or more digital values and capturing a derivative of the one or more digital values as the response. Authenticity of the component is determined by comparing the response with an expected response.
