The ubiquity of “things” is both a strength and a weakness when considering the potential of the Internet of things. The possibilities of what can be connected are, literally, endless. Firstly, there will not be just one IoT, there will be multiple, and each will differ and be largely disjointed from the rest. The things may be identical or different in terms of computing capability and overall significance. The things may be mobile or stationary, and it’s not immediately clear if security will be an issue in every use-case.
