Secure Over-The-Air Firmware Updates for Sensor Networks

Large-scale wireless sensor networks have been used in the Internet of Things (IoT) and other cyber-physical systems (CPS) to collect large amounts of data. One important practical issue in large-scale sensor networks is firmware updatesas updating many deployed sensors one by one is tedious. In this work, we study secure over-the-air (OTA) firmware updates for large-scale wireless sensor networks. We have designed a prototype system where a...
