OTA Secure Update System For IoT Fleets

In this paper, the authors present an Over-The-Air secure and scalable update system for Internet of Things fleets which run embedded Linux. The system uses the SWUpdate Linux update agent and Eclipse hawkBit framework to offer a scalable and server and client fault tolerant update mechanism for IoT fleets where no physical access is available. Security is achieved using the Linux OpenSSL library. By using Buildroot we implement a complete automated build system.
