Abstract: A system for verifying the integrity of unmanned aerial vehicles (UAVs), which is configured to reside in a UAV and interface with both the communications system of the UAV and the UAV's software and hardware resources. The UAV may be configured to execute firmware that obtains a serial number or unique identifier of hardware and software on the UAV, creates a hash code combination of such unique identifiers, encrypts the hash code, transmits the encrypted hash code over a wired or wireless communications system to another computer which maintains a table of the certified codes of each UAV which results in the computer authenticating the specific UAV (or not). The system also may determine whether a specific UAV's hardware or software has been changed since the UAV was last certified.
