The IoT will provide the communication infrastructure for a host of new fields of applications, including e.g. Smart Cities, Smart Grid, Intelligent Transport Systems and, perhaps most generally, Cyber-Physical Systems. These applications are likely to influence our lives to a degree previously unheard of. The associated required levels of security, privacy and trust, along with the highly multi-disciplinary nature of these applications and their respective functional requirements represents considerable challenges for the underlying standardisation process. This workshop will discuss these challenges and how the standardisation environment may live up to them.
