Security Evaluation of Cyber-Physical Systems in Society- Critical Internet of Things
In this paper, we present evaluation of security
awareness of developers and users of cyber-physical systems. Our
study includes interviews, workshops, surveys and one practical
evaluation. We conducted 15 interviews and conducted survey with
55 respondents coming primarily from industry. Furthermore, we
performed practical evaluation of current state of practice for a
society-critical application, a commercial vehicle, and reconfirmed
our findings discussing an attack vector for an off-line societycritical
facility. More work is necessary to increase usage of security
strategies, available methods, processes and standards. The security
information, currently often insufficient, should be provided in the
user manuals of products and services to protect system users. We
confirmed it lately when we conducted an additional survey of
users, with users feeling as left out in their quest for own security
and privacy. Finally, hardware-related security questions begin to
come up on the agenda, with a general increase of interest and
awareness of hardware contribution to the overall cyber-physical
security. At the end of this paper we discuss possible
countermeasures for dealing with threats in infrastructures,
highlighting the role of authorities in this quest
Experimental Study on Low Power Wide Area Networks (LPWAN) for Mobile Internet of Things
In the past decade, we have witnessed explosive growth in the number of
low-power embedded and Internet-connected devices, reinforcing the new
paradigm, Internet of Things (IoT). The low power wide area network (LPWAN),
due to its long-range, low-power and low-cost communication capability, is
actively considered by academia and industry as the future wireless
communication standard for IoT. However, despite the increasing popularity of
`mobile IoT', little is known about the suitability of LPWAN for those mobile
IoT applications in which nodes have varying degrees of mobility. To fill this
knowledge gap, in this paper, we conduct an experimental study to evaluate,
analyze, and characterize LPWAN in both indoor and outdoor mobile environments.
Our experimental results indicate that the performance of LPWAN is surprisingly
susceptible to mobility, even to minor human mobility, and the effect of
mobility significantly escalates as the distance to the gateway increases.
These results call for development of new mobility-aware LPWAN protocols to
support mobile IoT.Comment: To appear at 2017 IEEE 85th Vehicular Technology Conference (VTC'17

The Importance of Sensors to the Internet of Things
The excitement and hype surrounding the emerging technology market known as the Internet of Things
(IoT) has attracted a great deal of attention from industry, business leaders, and governments alike.
According to Cisco estimates1, the IoT will create a $14 Trillion global opportunity, and Business Insider
predict it will be the largest market for technology hardware ever 2. If these are correct, the impact on
traditional business models through the adoption of new technology within industry, the service sector
and governments will be transformational. At an individual and societal level, important areas such as
health care and aging population will particularly benefit from IoT. The changes on tomorrow’s society
can only be imagined but there is little doubt, whether individually, societally, economically, or
industrially, these changes will be far reaching.
However, the promise of future riches can fool the unwary into overlooking the jewels that already exist
which are delivering benefit to the UK economy today; whose presence will be pivotal to the UK’s position
in the IoT market of tomorrow. In the SILC white paper ‘The IoT Tree of Life’3, the 4 foundation roots from
which the IoT will develop are: Low Power Processing, Miniature Sensors, Ubiquitous Wireless, and
Power Efficiency. This briefing paper explores Sensor Systems, the ‘eyes and ears’ of the IoT, and
elucidates how the existing UK strengths in this area can be leveraged to deliver competitive advantage to
the UK economy in the emerging IoT market
Securing Real-Time Internet-of-Things
Modern embedded and cyber-physical systems are ubiquitous. A large number of
critical cyber-physical systems have real-time requirements (e.g., avionics,
automobiles, power grids, manufacturing systems, industrial control systems,
etc.). Recent developments and new functionality requires real-time embedded
devices to be connected to the Internet. This gives rise to the real-time
Internet-of-things (RT-IoT) that promises a better user experience through
stronger connectivity and efficient use of next-generation embedded devices.
However RT- IoT are also increasingly becoming targets for cyber-attacks which
is exacerbated by this increased connectivity. This paper gives an introduction
to RT-IoT systems, an outlook of current approaches and possible research
challenges towards secure RT- IoT frameworks
