Sensing is a major component of the IoT and an essential part of most Industrial IoT (IIoT) applications. By adding wireless connectivity and a microcontroller or other processor to a sensor node, one can create a smart sensor. These sensors can be widely distributed without need for a sensor hub. However, they then become extremely vulnerable targets for attackers. Without security, they can become a weak link in the system. Fortunately, the Trusted Computing Group (TCG) techniques that have been developed for other computing, network, wireless, and IoT applications are applicable to these sensor nodes as well. This topic will be explored at a TCG workshop at Sensors Expo in June.
