Blockchain-Aided Secure Communication Framework Intended for UAV Networks

Networks of Unmanned Aerial Vehicles (UAVs) have a lot of promise for use in commercial, military, and civil applications. The communication of UAV networks presents significant cybersecurity challenges as network sizes increase. Including blockchain technology in peer-to-peer UAV networks is one way to offer a safe, scalable communication method. Blockchain enables safe, decentralized, and collaborative communication between several entities. To increase the security and privacy of UAV network communication, this article proposes a method based on Blockchain Technology (BCT). The proposed model employs Elliptic Curve Diffie-Hellman (ECDH) to ensure confidentiality through secure key exchange and utilizes the Secure Hash algorithm (SHA) to maintain data integrity. The cloud platform is used to store technical data, integrity, authentication, availability, and confidentiality. The data is then stored on a public blockchain based on Ethereum to enable seamless BCT transactions. The suggested approach improves in defending private information against a variety of threats, including plaintext and ciphertext attacks.
