Lightweight Challenge-Response Authentication in SDN-Based UAVs Using Elliptic Curve Cryptography

Unmanned aerial vehicles (UAVs) (also known as drones) are aircraft that do not require the presence of a human pilot to fly. UAVs can be controlled remotely by operator or autonomously onboard computer systems. have many military uses, including battlefield surveillance, effective target tracking and engagement in air-to-ground warfare, situational awareness challenging circumstances. They also offer distinct advantage various applications such forest fire monitoring surveillance. Surveillance systems developed using advanced technologies modern era communications networks. As result, enhancements control manage efficiently. Network security is critical concern with respect due risk surveillance information theft physical misuse. Although several new tools been introduced secure networks, attackers use more methods get into UAV network create problems pose an organizational threat entire system. Security mechanisms reduce performance because some restrictive measures prevent users from accessing specific resources, but few techniques overcome problem reduction scenarios. There types attacks, i.e., denial service attacks (DOS), distributed (DDOS), address resolution protocol (ARP) spoofing, sniffing, etc., make it maintain network. This research paper proposes lightweight challenge-response authentication previously mentioned problems. provided utilizing minimum number bits memory, this technique offers same features while fewer low computing power consumption.
