ABSTRACT:
A verifier for remotely checking integrity of a device connected via a network, includes a calculator which fills free areas in a memory of the device with random numbers and generates a local check code; an interface which transmits integrity check parameters that are used by the device to generate a remote check code, to the device, and receiving the remote check code from the device; a determiner which detects a remote check code generation time and compares the detected remote check code generation time with a presorted remote check code generation expectation time; and a controller which confirms the integrity of the memory of the device when the remote check code generation time does not exceed the remote check code generation expectation time according to a result of the determination and the local check code matches the remote check code.
