Abstract
A manufacturer of computing equipment may generate a signature for computing equipment by measuring various attributes of the computing equipment, such as the impedance across circuits included in the computing equipment. Verification equipment may be provided to a recipient of the computing equipment. The verification equipment may be configured to generate a signature of the computing equipment over a physical connection between the verification equipment and the computing equipment. A determination may be made whether the computing equipment has been tamper with based at least in part on the signature generated by the manufacturer and the signature generated by the recipient.
