With the popularity of unmanned aerial vehicles (UAVs), more and more valuable data can be collected by UAVs. In order to balance the data usage and communication cost, the data can be preprocessed in UAVs rather than directly transmitting to the data centre in the edge computing paradigm. Users can obtain information of interest by accessing the data centre remotely by authenticating themselves to the data centre using the most pervasive password authentication method. Unfortunately, the data centre becomes the main attack target because it not only stores the data but also maintains the passwords of all the users. Aiming at protecting the data as well as the password in the UAV-enabled mobile edge computing environment, the authors combine the advantages of gateway-oriented password authenticated key exchange (PAKE) protocols and two-server PAKE protocols and put forward an efficient gateway-oriented two-server PAKE protocol. The security of the proposed protocol is given in the random oracle model. The performance comparison shows their proposal has comparable efficiency in computation and communication costs. Their protocol provides better protection to the password without sacrificing efficiency. Consequently, their protocol is more suitable for real applications in UAV-enabled mobile edge computing environment.

移动边缘计算中面向网关的无人飞行器两服务器密码认证密钥交换协议

随着无人机的普及，无人机可以收集越来越多的有价值的数据。为了平衡数据使用和通信成本，可以在UAV中对数据进行预处理，而不是直接在边缘计算范式中传输到数据中心。用户可以通过使用最普遍的密码身份验证方法向数据中心进行身份验证来远程访问数据中心，从而获得感兴趣的信息。不幸的是，数据中心成为主要的攻击目标，因为它不仅存储数据，而且维护所有用户的密码。为了保护启用了无人机的移动边缘计算环境中的数据和密码，作者结合了面向网关的口令认证密钥交换协议（PAKE）和两服务器PAKE协议的优点，提出了一种高效的面向网关的两服务器PAKE协议。所提出协议的安全性在随机预言模型中给出。性能比较表明，他们的建议在计算和通信成本方面具有可比的效率。他们的协议在不牺牲效率的情况下为密码提供了更好的保护。因此，它们的协议更适合于启用了无人机的移动边缘计算环境中的实际应用。性能比较表明，他们的建议在计算和通信成本方面具有可比的效率。他们的协议在不牺牲效率的情况下为密码提供了更好的保护。因此，它们的协议更适合于启用了无人机的移动边缘计算环境中的实际应用。性能比较表明，他们的建议在计算和通信成本方面具有可比的效率。他们的协议在不牺牲效率的情况下为密码提供了更好的保护。因此，它们的协议更适合于启用了无人机的移动边缘计算环境中的实际应用。
