Abstract
A peripheral device includes an interface configured to communicate with a computer, the peripheral device; logic configured to perform an integrity verification of an operating system of the computer; and a display configured to display a result of the integrity verification. A method for integrity verification of a computer using a peripheral device includes connecting the peripheral device to the computer; sending a challenge from the device to the computer; computing attestation data using the challenge and information stored in the computer, retrieving the attestation data from the computer by a client program running on the computer; sending the attestation data to the peripheral device; and verifying the attestation data by the peripheral device.
