An Approach to Remote Update Embedded Systems in the Internet of Things

There is a growing initiative on the part of regulatory bodies to employ control over firmware emissions destined for Internet of Things (IoT) devices. In this scenario, this paper presents a new approach, called SOTARU, which proposes the use of a consortium Blockchain among embedded system manufacturers as a way to allow access to the update history of devices from multiple manufacturers through a single infrastructure. The security and robustness of the proposal were evaluated with the help of the Common Open Research Emulator (CORE) distributed network emulator. As a result, it was found that SOTARU stands out in terms of security when compared to other approaches proposed in the literature, as well as being functional even in high latency scenarios.
