As part of a recently started project, a custom communication platform will be installed in LED street lights. This platform will monitor important parameters of the electronic components inside the street light with the goal of identifying their degradation over time. The platform will have access to the DALI bus controlling the driver of the street light, which can be used to turn the light off. Thus, it is considered a safety-critical application.
As the street light is installed on a mast at a substantial height, the data captured over the course of the project will have to be retrieved wirelessly. To prevent attackers from seizing control over the custom platform its communication has to be thoroughly secured.
In this work a systematic approach for securing the aforementioned communication channel should be developed and the proposed scheme implemented.
