论文摘要
在许多情况下，智能设备上外围设备外围设备的可靠控制是安全和隐私的关键。记者希望在调查报告中可靠地关闭收音机以保护其来源。用户希望确保在私人会议期间可靠地关闭摄像头和麦克风。在本文中，我们提出了Secloak，这是一种基于ARM Trustzone的解决方案，即使平台软件受到损害，也可以确保对外围设备的可靠控制。我们设计了一个安全的内核，该内核与在移动设备（例如Android和Linux）上运行的软件共存，而无需进行任何代码修改。 Android原型表明，可以通过非常小的值得信赖的计算基础来可靠地控制收音机，摄像头和麦克风等移动外围设备，并且性能最低。
Reliable on-off control of peripherals on smart devices is a key to security and privacy in many scenarios. Journalists want to reliably turn off radios to protect their sources during investigative reporting. Users wish to ensure cameras and microphones are reliably off during private meetings. In this paper, we present SeCloak, an ARM TrustZone-based solution that ensures reliable on-off control of peripherals even when the platform software is compromised. We design a secure kernel that co-exists with software running on mobile devices (e.g., Android and Linux) without requiring any code modifications. An Android prototype demonstrates that mobile peripherals like radios, cameras, and microphones can be controlled reliably with a very small trusted computing base and with minimal performance overhead.
