During the past few years, as Internet of Things develops rapidly, the applications of unmanned aerial vehicle (UAV) technology have been increasingly widely used. Meanwhile, the efficiency and security issues of UAV communication have brought about widespread attention of many researchers in different fields. In an open wireless network, the attacks on UAV communication mainly include eavesdropping, tampering, interrupting, forgery, etc. Signcryption is an appropriate method to address these security problems. However, the existing signcryption schemes are not suitable for UAVs with limited resources and ground station (GS) that needs to process a large number of messages from UAVs. Moreover, in a certain area, UAVs and a GS may belong to different cryptosystems. Therefore, in this article, we came up with a heterogeneous signcryption scheme for UAVs to communicate to a GS (HSC-U2G) without bilinear pairing operation, where UAVs belong to identity-based cryptography (IBC) while the GS belongs to public-key infrastructure (PKI). Moreover, our scheme provides identity privacy for UAVs and supports batch verification for the GS. Using the random oracle model, we demonstrate HSC-U2G can achieve insider security for confidentiality as well as unforgeability. After that, HSC-U2G is compared with several important related works and we provide all experimental results to show the efficiency.

无人机免配对异构签密方案


近年来，随着物联网的快速发展，无人机技术的应用日益广泛。同时，无人机通信的效率和安全问题引起了不同领域众多研究人员的广泛关注。在开放的无线网络中，对无人机通信的攻击主要包括窃听、篡改、中断、伪造等，签密是解决这些安全问题的合适方法。然而，现有的签密方案不适合资源有限的无人机和需要处理来自无人机的大量消息的地面站（GS）。而且，在某个区域，无人机和GS可能属于不同的密码系统。因此，在本文中，我们提出了一种无需双线性配对操作的无人机与 GS 通信的异构签密方案（HSC-U2G），其中无人机属于基于身份的密码学（IBC），而 GS 属于公钥基础设施（PKI）。此外，我们的方案为无人机提供身份隐私，并支持GS的批量验证。使用随机预言模型，我们证明 HSC-U2G 可以实现内部安全，确保机密性和不可伪造性。之后，HSC-U2G 与几个重要的相关工作进行了比较，并提供了所有实验结果来展示其效率。
