Abstract
Technologies pertaining to attesting to computer-executable code residing on a robot are described herein. An attestation server includes a database that comprises file paths that correspond to files on the robot at a time of manufacture of the robot. The database also includes file digests that are indicative of content of the files on the robot. The attestation server randomly selects a file path and transmits the file path to the robot. The robot accesses the file at the file path and computes a file digest for that file. The robot then transmits the file digest to the attestation server, which compares the file digest from the robot with the file digest in the database. If the file digests match, then the attestation server attests to the computer-executable code on the robot.
