Secure Communications in Unmanned Aerial Vehicle Network

摘要

The unmanned aerial vehicle (UAV) network has attracted much attention in industry and academia. However, a UAV as a vital information carrier and data relay platform is prone to various attacks. In this paper, we propose a secure communication scheme for UAV network. In our scheme, each drone maintains and manages an area in which the authorized devices can obtain a broadcast key without an online centralized authority. By employing the hierarchical identity-based broadcast encryption and pseudonym mechanism, all the devices in this system can broadcast encrypted messages anonymously and decrypt the legal cipher-text. The analysis shows that our scheme satisfies four important security properties of confidentiality, authentication, partial privacy-preservation and resistance to denial of service attacks. Experiments show that our scheme incurs a delay of only a couple of milliseconds.
