Guest Editorial: Trustworthiness in Industrial Internet of Things Systems and Applications

Trustworthiness is the probability that a system will function according to intended behaviors under a set of circumstances as demonstrated by qualities including, but not limited to safety, security, privacy, reliability, real timeliness. Trustworthiness in the industrial Internet of Things (IIoT) systems and applications is crucial to a vital expectation of industrial investors. Preserving the trustworthiness of such a system and network is crucial to void cost, time, and loss of lives. A trustworthy IIoT system considers both the security characteristics and system functionalities (faults, failures) of IoT trustworthiness. Traditional security systems, tools, techniques, and apps are not enough to protect the IIoT platform due to the practical facts in real industrial environments, diverse protocols, constrained upgrade opportunities, mismatch in protocols, and resource constraints in the industrial system. Regarding these concerns, this special section targets to bring up-to-date research results of IIoT systems and applications with the trustworthiness support. This leads to steady operations and high-quality results and improved safety in the IIoT.
