物联网 (IoT) 在我们的生活中变得越来越流行。物联网设备通常是为传感或驱动目的而设计的。然而，物联网设备上当前的传感系统缺乏对传感需求的理解，当多个传感应用需要使用传感器资源时，这会降低传感的灵活性、隔离性和安全性。在这项工作中，我们提出了 VirtSense，一种基于 ARM TrustZone 的虚拟传感系统，为每个传感应用程序提供一个虚拟传感器实例，从而进一步在物联网设备上实现安全、灵活和隔离的传感环境。我们的初步结果表明，VirtSense：1）可以为每个传感应用程序提供虚拟传感器实例，从而满足每个应用程序的传感需求而不影响其他应用程序； 2）即使在不受信任的环境下也能够执行访问控制策略。
Internet-of-Things (IoTs) are becoming more and more popular in our life. IoT devices are generally designed for sensing or actuation purposes. However, the current sensing system on IoT devices lacks the understanding of sensing needs, which diminishes the sensing flexibility, isolation, and security when multiple sensing applications need to use sensor resources. In this work, we propose VirtSense, an ARM TrustZone based virtual sensing system, to provide each sensing application a virtual sensor instance, which further enables a safe, flexible and isolated sensing environment on the IoT devices. Our preliminary results show that VirtSense: 1) can provide virtual sensor instance for each sensing application so that the sensing needs of each application will be satisfied without affecting others; 2) is able to enforce access control policy even under an untrusted environment.
