AUTHENTICATION USING CURRENT DRAWN BY SECURITY DEVICE

A method for determining authenticity of a component in an imaging device is disclosed. Embodiments of the present disclosure provide a method for a device to authenticate a second device using an electronic authentication scheme while overcoming vulnerabilities associated with sending data over a communication bus when performing authentication by using information other than information transmitted over a shared bus as authentication parameters. Embodiments utilize, as an authentication parameter, a current drawn by a chip from a power source when the chip performs an operation in response to a command.
