The Internet of Drones (IoD) is a network for drones that utilizes the existing Internet of Things (IoT) infrastructure to facilitate mission fulfilment through real-time data transfer and navigation services. IoD deployments, on the other hand, are often conducted in public wireless settings, which raises serious security and privacy concerns. A key source of these security and privacy concerns is the fact that drones often connect with one another through an unprotected wireless channel. Second, limits on the central processing unit (CPU), sensor, storage, and battery capacity make the execution of complicated cryptographic methods onboard a drone impossible. Signcryption is a promising method for overcoming these computational and security limitations. Additionally, in an IoD setting, drones and the ground station (GS) may employ various cryptosystems in a particular region. In this article, we offer a heterogeneous signcryption scheme with a conditional privacy-preservation option. In the proposed scheme, identity-based cryptography (IBC) was used by drones, while the public key infrastructure (PKI) belonged to the GS. The proposed scheme was constructed by using the hyperelliptic curve cryptosystem (HECC), and its security robustness was evaluated using the random oracle model (ROM). In addition, the proposed scheme was compared to the relevant existing schemes in terms of computation and communication costs. The results indicated that the proposed scheme was both efficient and secure, thereby proving its feasibility.
无人机物联网（IoD）是一个用于无人机的网络，它利用现有的物联网（IoT）基础设施，通过实时数据传输和导航服务来实现任务。另一方面，IoD 的部署通常在公共无线环境中进行，这引发了严重的安全和隐私问题。这些安全和隐私问题的一个主要来源是无人机通常通过未受保护的无线信道相互连接。其次，中央处理单元（CPU）、传感器、存储和电池容量的限制使得在无人机上执行复杂的加密方法变得不可能。签密是克服这些计算和安全限制的一种有前途的方法。此外，在 IoD 环境中，无人机和地面站（GS）可能在特定区域中使用各种密码系统。在本文中，我们提出了一种具有条件隐私保护选项的异构签密方案。在提出的方案中，无人机使用基于身份的密码学（IBC），而 GS 使用公钥基础设施（PKI）。该方案是使用超椭圆曲线密码系统（HECC）构建的，并使用随机 oracle 模型（ROM）评估了其安全性和稳健性。此外，还对该方案的计算和通信成本与相关的现有方案进行了比较。结果表明，所提出的方案既高效又安全，从而证明了其可行性。
