Recently, the deployment and usage of unmanned aerial vehicles (UAVs) to monitor and track a geographical region have been increased exponentially. The network infrastructure designed to deploy UAVs consists of sensors, actuators, and other communication smart devices for data collection and processing. As security and privacy is one of the challenging tasks in such an environment, so to design an efficient and secure data dissemination scheme is a challenging task due to limited storage and computation power of UAVs. To mitigate various attacks in such an environment, several efficient signature schemes were proposed in the literature. However, none of these schemes work well due to high computation and communication costs. To overcome these challenges, this paper presents a short proxy signature (CB-PS) scheme in certificate-based setting. Due to implicit usage of certificates, CB-PS solves inherent key escrow of ID-based designated verifier proxy signature. It also eliminates the necessity of secret key distribution in ID-based schemes. The proposed CB-PS scheme is adaptively unforgeable in a random oracle model. It is also efficient with respect to both signature length and computational complexity. The comparison of computational costs reveals that the proposed scheme consumes the least cost 15.45 ms in comparison to the costs of existing competitive schemes.

CB-PS：一种用于无人机的高效基于短证书的代理签名方案

近来，用于监视和跟踪地理区域的无人机（UAV）的部署和使用已成倍增加。设计用于部署无人机的网络基础设施包括传感器，执行器和其他用于数据收集和处理的通信智能设备。由于安全和隐私是这种环境中的挑战性任务之一，因此，由于无人机的存储和计算能力有限，设计高效而安全的数据分发方案是一项挑战性任务。为了减轻这种环境下的各种攻击，文献中提出了几种有效的签名方案。然而，由于高计算和通信成本，这些方案都不能很好地工作。为了克服这些挑战，本文提出了一种基于证书设置的短代理签名（CB-PS）方案。由于证书的隐式使用，CB-PS解决了基于ID的指定验证者代理签名的固有密钥托管。它还消除了在基于ID的方案中分发密钥的必要性。所提出的CB-PS方案在随机预言模型中是自适应不可伪造的。关于签名长度和计算复杂度，它也是有效的。计算成本的比较表明，与现有竞争方案的成本相比，该方案消耗的成本最低，为15.45 ms。就签名长度和计算复杂度而言，它也是有效的。计算成本的比较表明，与现有竞争方案的成本相比，该方案消耗的成本最低，为15.45毫秒。关于签名长度和计算复杂度，它也是有效的。计算成本的比较表明，与现有竞争方案的成本相比，该方案消耗的成本最低，为15.45毫秒。
