In the modern era, new and innovative ways of securing data and communications are continuously developing. One such recent development is using the concept of DNA as a means of data encryption. In this work, we propose a new approach to encrypt data and communications on the MAVLink protocol for unmanned aerial vehicles (UAVs) using a lightweight GIFT algorithm and dynamic DNA coding (with binary bits). MAVLink is a communication protocol for UAVs, which is currently unencrypted and can easily be intercepted by anyone. As such, a secure MAVLink protocol has long been needed in the UAV industry. We describe a novel secure communication protocol for UAVs using dynamic DNA coding to encrypt MAVLink packets, which we call DMAV. Experimental results show that this novel means of securing the MAVLink protocol performs better than the traditional method (i.e., using public and private key cryptography). Therefore, the proposed approach could potentially change the way secure communications are conducted between UAVs in the future. [ABSTRACT FROM AUTHOR]

Most interesting area is the growing demand of flying-IoT mergers with smart cities. However, aerial vehicles, especially unmanned aerial vehicles (UAVs), have limited capabilities for maintaining node energy efficiency. In order to communicate effectively, IoT is a key element for smart cities. While improving network performance, routing protocols can be deployed in flying-IoT to improve latency, packet drop rate, packet delivery, power utilization, and average-end-to-end delay. Furthermore, in literature, proposed techniques are verymuch complex which cannot be easily implemented in realworld applications. This issue leads to the development of lightweight energyefficient routing in flying-IoT networks. This paper addresses the energy conservation problem in flying-IoT. This paper presents a novel approach for the internet of flying vehicles using DSDV routing. ISH-DSDV gives the notion of bellman-ford algorithm consisting of routing updates, information broadcasting, and stale method. DSDV shows optimal results in comparison with other contemporary routing protocols. Nomadic mobility model is utilized in the scenario of flying networks to check the performance of routing protocols. [ABSTRACT FROM AUTHOR]

The United States has accumulated an unequivocal ability to collect intelligence as a result of the technological advances of the 20th century. Numerous methods of collection have been employed in clandestine operations around the world including those that focus on human, signals, geospatial, and measurements and signals intelligence. An infatuation with technological methods of intelligence gathering has developed within many intelligence organizations, often leaving the age old practice of espionage as an afterthought. As a result of the focus on technical methods, some of the worst intelligence failures of the 20th century can be attributed to an absence of human intelligence. The 21st century has ushered in advances in technology have allowed UAVs to become the ultimate technical intelligence gathering platform; however human intelligence is still being neglected. The increasing reliance on UAVs will make the United States susceptible to intelligence failures unless human intelligence can be properly integrated. In the near future UAVs may be able to gather human level intelligence, but it will be a long time before classical espionage is a thing of the past. [ABSTRACT FROM AUTHOR]
