Dependability and Security of IoT Network

Dear Colleagues,

The internet of things (IoT) emerged as a general umbrella of connected technologies with massive data transactions generated by a vast number of heterogeneous things. IoT networks have been developed and adopted in a vast number of ecosystems, such as the internet of medical things (IoMT) in the field of medical healthcare, the internet of industrial things (IoIT) in industrial factories, the internet of robotic things (IoRT) in mechatronics, the internet of vehicle things (IoVT) in transportation, (which are abbreviated as Io*T), etc. Modern Io*T networks are constructed on top of a sophisticated and multi-level infrastructure of heterogeneous hardware/software systems, subsystems, and underlying components. Furthermore, the computing power and storage capabilities of IoT networks often rely on well-known computing backbones, including cloud/fog/edge computing paradigms, while sensing and data gathering rely on pervasiveness and ubiquity of sensors/devices at the very edge of the overall network. The IoT infrastructures, in practice, are strictly required with: 1) hosting latency-sensitive and likely real-time applications and services across the infrastructure; 2) a huge volume of data at a high-level of heterogeneity generated by IoT sensors/devices are seamlessly synchronized, stored, and processed across the infrastructure often at a high data transaction rate; and 3) a high level of dependability, and security measures are strictly required to satisfy a high level of data accuracy, economically operational costs, and user expectations for all operations at all levels of the IoT infrastructure.

Dependability and security are of five distinctive natures (along with functionality, performance, and cost) for computing and communication systems. Without exceptions, IoT networks with a sophisticated composition of multi-level systems and things are inevitably prone to a chain of threats (faults, errors, and failures) which eventually causes fatal losses, such as service interruption/outage, data leak, or even human lives. Even a 1% failure rate is too high, because it causes 3.65 days of unscheduled downtime in a year which, in turn, may reduce an enormous amount of enterprise turnover. Therefore, dependability and security requirements should be taken into consideration to obtain the highest level of trustworthiness for IoT-based infrastructures, in practice.

This Special Issue targets scientific contributions tackling these issues. Topics of interest include but are not limited to:

Keywords:

- IoT’s dependability and security modelling and evaluation;
