Unmanned aerial vehicle (UAV) technologies have a promising application prospect. It is necessary to use digital signature schemes to protect the integrity and authentication of messages in the UAV networks. According to the characteristics of UAV networks, digital signature schemes should solve the problems of digital certificate management and key escrow, guarantee the real-time performance of UAV executing commands, and ensure that only the designated verifier can verify the signature. Therefore, we proposed a certificateless designated verifier proxy signature (CLDVPS) scheme which meets the requirements. We proved our signature scheme is existentially unforgeable under an adaptive chosen message attack in the random oracle model and compared the efficiency of our signature scheme with other signature schemes. We implemented these signature schemes in jPBC to obtain the computing time and theoretically analyzed signature length of these signature schemes. The analysis results indicate that our CLDVPS scheme is more efficient than most of other related signature schemes on computation costs and also efficient on communication costs.

无人机技术具有广阔的应用前景。必须使用数字签名方案来保护UAV网络中消息的完整性和身份验证。根据无人机网络的特点，数字签名方案应解决数字证书管理和密钥托管的问题，保证无人机执行命令的实时性，并确保只有指定的验证者才能验证签名。因此，我们提出了一种符合要求的无证书指定验证者代理签名（CLDVPS）方案。我们证明了我们的签名方案在随机预言机模型下的自适应选择消息攻击下是不可伪造的，并将我们的签名方案与其他签名方案的效率进行了比较。我们在jPBC中实现了这些签名方案，以获得计算时间并从理论上分析了这些签名方案的签名长度。分析结果表明，我们的CLDVPS方案在计算成本上比大多数其他相关签名方案更有效，并且在通信成本上也很有效。
