Abstract: Disclosed herein are an apparatus and method for managing remote attestation. The apparatus includes one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program may request a gateway to verify the integrity of devices connected with the gateway, receive a verification result about whether the integrity of the devices is damaged from the gateway, identify a device, the integrity of which is damaged, using the verification result, perform detailed integrity verification on the device, the integrity of which is damaged, in order to identify an object, the integrity of which is damaged, and perform an operation for responding to the object, the integrity of which is damaged.
