Abstract
With the rapid development of information technology and the increasing application of UAV in various fields, the security problems of unmanned aerial vehicle (UAV) communication network have become increasingly prominent. It has become an important scientific challenge to design a routing protocol that can provide efficient and reliable node to node packet transmission. In this paper, an efficient Digital Signature algorithm based on the elliptic curve cryptosystem is applied to routing protocol, and an improved security method suitable for on-demand routing protocol is proposed. The UAV communication network was simulated through the NS2 simulation platform, and the execution efficiency and safety of the improved routing protocol were analyzed. In the simulation experiment, the routing protocols of ad-hoc on demand distance vector (AODV), security ad-hoc on demand distance vector (SAODV), and improved security ad-hoc on demand distance vector (ISAODV) are compared in terms of the performance indicators of packet delivery rate, throughput, and end-to-end delay under normal conditions and when attacked by malicious nodes. The simulation results show that the improved routing protocol can effectively improve the security of the UAV communication network.

With the progress and development of science and technology, unmanned aerial vehicle (UAV) is becoming more and more mature in technology and widely used in production and life
In order to adapt to the limited resources in UAV communication network, this paper studies a secure and efficient digital signature scheme based on security ad-hoc on demand distance vector (SAODV) routing protocol
The elliptic cryptosystem is introduced communication network good performance, but its into routing protocol to complete the authentication function, andhas an improved secure routing into routing protocol to complete the authentication function, and an improved secure security isisproposed poor andbased it is easy to advantages be attacked.ofInthe thisexisting paper, SAODV
Summary
With the progress and development of science and technology, UAV is becoming more and more mature in technology and widely used in production and life. It is important to design a routing digital signature algorithm based on elliptic curve cryptosystem is applied to routing protocol, protocol that can provide efficient and reliable node to node packet transmission. An efficient digital signature algorithm based on elliptic curve cryptosystem is applied to routing protocol, and an improved security method suitable for on-demand routing protocol is proposed. The ISAODV routing protocol proposed in this paper effectively reduces the complexity of the algorithm on the basis of improving network security, and provides a powerful guarantee for the security of UAV communication networks.
