Security-Aware Design of Cyber-Physical Systems for Control Applications

By expansion of IoT in the recent years, cyber-physical systems are more and more exposed to security threats. In his dissertation, Rouhollah Mahfouzi has focused on security threats to
control applications in cyber-physical systems. Rouhollah has provided detection, prevention,
and mitigation solutions to attacks considering the stringent resource constraints and important properties of such systems.

Social Robots as Intentional Agents

Robotic systems, such as autonomous vehicles and humanoid robots, are typically technologically complex. This means that their actions can be difficult to understand and predict. According to findings presented in Sam Thellman´s dissertation, this means that people who encounter such systems in their daily lives may sometimes have to consider what these systems "know" and "want" to interact purposefully with them. The dissertation analyses the problem of ascribing the specific beliefs and desires to robots that are conducive to predicting their behavior. It identifies ascriptions of beliefs that depend on what the robot can and cannot perceive in the environment as a particularly challenging aspect of this broader problem. An important implication of the dissertation is that the assumptions that drive folk-psychological ascriptions to robots need to be studied in considerably more detail in the future.

Suleman Khan together with Andrei Gurtov and colleagues from Vrije Universiteit Brussel and Swansea University, received the Best Student Paper Award at INCS 2021 (the 21st Integrated Communications, Navigation, and Surveillance Conference) for the paper "A Security Model for Controller-Pilot Data Communication Link".

Parameterized Verification of Synchronized Concurrent Programs

There is currently an increasing demand for concurrent programs. Checking the correctness of concurrent programs is a complex task due to the interleavings of processes. Sometimes, violation of the correctness properties in such systems causes human or resource losses; therefore, it is crucial to check the correctness of such systems.

Formal verification is the approach for proving program correctness. Model checking is a formal verification technique that is suitable for concurrent programs. It aims to automatically establish the correctness (expressed in terms of temporal properties) of a program through an exhaustive search of the behavior of the system. Model checking was initially introduced for the purpose of verifying finite-state concurrent programs, and extending it to infinite-state systems is an active research area.

In her PhD thesis, Zeinab Ganjei studied formal verification of parameterized systems. That is, systems in which the number of executing processes is not bounded a priori. She provided fully-automatic and parameterized model checking techniques for establishing the correctness of safety properties for certain classes of concurrent programs such as 1) phaser programs, 2) programs that count the number of threads satisfying different predicates, and 3) a class of fault-tolerant distributed programs described in the Heard-Of (HO for short) model.

IDA's award for best online teaching

During the past year, most of IDA's teaching has been conducted online, and all of our teachers have put a lot of work and energy into reorganizing their classes. Many have developed new pedagogical approaches and produced new teaching material.
IDA would like to showcase some of the best examples and draw attention to our teachers’ remarkable pedagogical and technical competence through an award for best online teaching. The prize is awarded for a recorded teaching component, such as an online lecture or a seminar.
The prize money is SEK 20,000.
All nominated contributions will be reviewed by a jury and the winner will be announced at the end of the summer.
Terms and Conditions:
• The purpose is to inspire further improvements in distance education by highlighting good examples of how the medium can be used in a pedagogical context.
• Only recorded entries will be considered. (The jury is not available to judge live teaching at any time.)
• Only IDA teachers, i.e., employees and part-time assistants (?) who lead IDA's courses, can be nominated.
• Only IDA courses in undergraduate or commissioned (?) education will be considered, i.e., the focus is on pedagogical material for our students. Courses from all faculties and study programs are welcome, including independent courses.
• The material can be in Swedish or English.
• The assessment will be made based on a section of the submitted material. (The jury cannot look through hours of lectures/seminars, and therefore they reserve the right to "fast-forward".)
• It is possible to nominate newly recorded material, i.e., it is permitted to re-record a section of a previous lecture or seminar for the purpose of improvement.
• The prize is handled in the same way as IDA's prizes for good teaching efforts (course evaluations>4), i.e., the prize amount can be used for anything that supports teaching at IDA: competence development, study trips, equipment, etc.
• The prize is given to the teacher or group that developed the material. The prize may be shared among several teachers/groups, at the jury’s discretion. Submitted entries must be publicly available (preferred) or made available to the jury (e.g., by login).
• Winners are expected to make the recording publicly available as inspiration for other teachers.
• The jury cannot be bribed

Nomination procedure:
Anyone, both employees and students, can nominate instructional content for this award. To submit a nomination, send a link to the recording together with a short description of how the video submission fits into the course (or equivalent). Do not attach large files / movies.

Email nominations to: Erika Larsson, erika.larsson@liu.se

Deadline for nominations: June 7, 2021

The jury consists of:
Carl Magnus Bruhner, Student Representative
Inger Erlander Klein, chair DM-nämnden
Ulf Nilsson, former Dean

Vulnerability and Risk Analysis Methods and Application in Large Scale Development of Secure Systems

Software products are building blocks of today’s connected society, and design and implementation of resilient software products is one of the challenging areas for software vendors. It is specially challenging to comply to cyber security standards and legislations where it is expected that cyber security risks are well understood and addressed.
In a recent PhD thesis at IDA, Shanai Ardi addressed some of these challenges faced by software vendors and presented two approaches to reduce the risk of introducing security weaknesses to software products during the software life cycle. The first approach is a technically sustainable software security process to develop a deep understanding of software vulnerabilities and their causes and how to improve software development processes by deploying security activities. The second approach is a security risk assessment method introduced to the requirements engineering phase to identify security risks in functional requirements at a low level of abstraction. A case study spanning four years describes how this approach is transferred form theoretical research results to regular use in a large enterprise.
