便携式法拉第笼中安全的User-Friendly无线固件分发
Secure and User-Friendly Over-the-Air Firmware Distribution in a Portable Faraday Cage
摘要:
建立一个大规模的无线传感器网络是具有挑战性的,因为固件必须是分布式的,传感器节点和后端之间的信任需要建立。为了有效地执行这项任务,我们提出了一种名为Box的方法,该方法利用了智能法拉第笼(FC)。FC从后端获取固件映像和密钥,用密钥修补固件,并通过空中将那些定制映像部署到放置在FC中的传感器节点。电磁屏蔽保护这种交换免受被动攻击者的攻击。我们对传感器节点的要求很少,不需要额外的硬件组件或制造商定制的固件。我们描述了这种新的工作流程,实现框和后端系统,并通过批量部署固件到多个商业现成的传感器节点,证明了我们的方法的可行性。我们与31名具有不同背景的参与者进行了用户研究,发现我们的方法比通过有线连接分发固件更快,更用户友好。
英文摘要:
Setting up a large-scale wireless sensor network is challenging, as firmware must be distributed and trust between sensor nodes and a backend needs to be established. To perform this task efficiently, we propose an approach named Box, which utilizes an intelligent Faraday cage (FC). The FC acquires firmware images and secret keys from a backend, patches the firmware with the keys and deploys those customized images over the air to sensor nodes placed in the FC. Electromagnetic shielding protects this exchange against passive attackers. We place few demands on the sensor node, not requiring additional hardware components or firmware customized by the manufacturer. We describe this novel workflow, implement the Box and a backend system and demonstrate the feasibility of our approach by batch-deploying firmware to multiple commercial off-the-shelf sensor nodes. We conduct a user-study with 31 participants with diverse backgrounds and find, that our approach is both faster and more user-friendly than firmware distribution over a wired connection.
