In recent years, with the improvement of drone technology, various demands using drones have been increasing. As a result, security of drones is becoming more and more important. One of the measures is the encryption of drone communication. Since drones need to be lightweight, it is necessary to use secret key cryptography instead of public key cryptography. In related research, the secret key was shared in advance, but this is inefficient. In the proposed method, the secret key is dynamically created and shared using the drone's movement history and radio wave strength. the key match rate under varying SNR is evaluated, and the proposed method is shown to be effective.
