Development of algorithms for MAV security

This paper describes the various security schemes required for incorporating security to the data being transmitted over the wireless link between a Micro Air Vehicle (MAV) and Ground Control Station (GCS). The suggested security schemes are developed in software and is integrated with the open source communication protocol i.e., MAVLink. The ciphers used in the adapted method are, Advanced Encryption Standard in Counter mode (AES-CTR) algorithm is used for data encryption, SHA-256 for key Hashing and Diffie-Hellman(D-H) for key exchange. This provides both encryption and authentication to the MAV communication, So that it results in improved security and integrity of the system in the real time applications.
