物联网（IoT）的普及引起了人们对物联网安全的广泛关注，特别是最近发生了几起与物联网设备相关的安全事件。由于许多物联网设备的资源约束性质，安全卸载已经被提出，以最小的设备开销为物联网提供足够好的安全性。在本文中，我们研究了与安全卸载相关的不可避免的风险：从物联网设备到卸载安全机制的不受保护和不受监控的传输。由于需求波动和基础设施不稳定，物联网的动态性是安全风险建模的一个重要挑战。我们提出了一个随机模型来捕捉物联网系统的预期和最坏情况的安全风险。然后，我们提出了一个框架，以有效地解决物联网中安全机制的最佳稳健部署。我们使用大量模拟的结果来证明与其他几种算法相比，我们的方法具有出色的性能和效率。
Popularization of the Internet-of-Things (IoT) has brought widespread concerns on IoT security, especially in face of several recent security incidents related to IoT devices. Due to the resource-constrained nature of many IoT devices, security offloading has been proposed to provide good-enough security for IoT with minimum overhead on the devices. In this paper, we investigate the inevitable risk associated with security offloading: the unprotected and unmonitored transmission from IoT devices to the offloaded security mechanisms. An important challenge in modeling the security risk is the dynamic nature of IoT due to demand fluctuations and infrastructure instability. We propose a stochastic model to capture both the expected and worst-case security risks of an IoT system. We then propose a framework to efficiently address the optimal robust deployment of security mechanisms in IoT. We use results from extensive simulations to demonstrate the superb performance and efficiency of our approach compared to several other algorithms.
