A method to enhance the security of UAV manet network

Abstract

The invention discloses a method of enhancing UVA (Unmanned Aerial Vehicle) MANET network security in the field of wireless communication technology. The method of enhancing UVA MANET network securitycomprises the specific steps as follows: S1, performing bidirectional identity authentication between UVA nodes, to be specific, S1.1, sending an identity authentication request to a UVA node A by aUVA node B, S1.2, responding to the identity authentication request of the UVA node A by the UVA node B, and S1.3, sending the identity authentication request to the UVA node A by the UVA B, and S1.4,responding to the identity authentication request of the UVA node B by the UVA node A; S2, negotiating symmetric master keys; S3, generating a session key; and S4, generating a digital signature, tobe specific, signing a message M and then sending the message signature sigma and the message M to the UVA node B by the UVA node A, and verifying the correctness of the signature by the node B. By adoption of a form of double keys, a key trusteeship problem and possibility of revealing a system private key due to inverse derivation of a malicious node can be well overcome through a negligible calculated amount.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for enhancing the security of an unmanned aerial vehicle MANET network. Background technique [0002] In recent years, the method of cooperative operation between UAVs through networking has received widespread attention. Its fields of application include: [0003] Wireless networking: One application of drone networking is to access the Internet. In February 2016, Internet giant Google (Google) planned to launch the UAV aerial networking project - SkyBender. The project aims to use solar drone networking as an Internet access platform. FACEBOOK acquired Ascenta Aerospace, using the company's drones to provide Internet access to developing countries through aerial networking. [0004] Joint search and rescue: Search and rescue are all time-sensitive tasks that need to cover a wide target area in a short period of time. The efficiency of a single drone ...

Problems solved by technology

Certificateless public key cryptography avoids the shortcomings of key escrow by improving the generation process of user private keys, but because most of the current certificateless key management schemes use bilinear pairing operations, the computational complexity is too large

Therefore, neither the existing certificate-based security schemes and identity-based schemes nor the existing certificate-based schemes are not suitable for distributed, self-organizing and autonomous UAV MANET networks
