New paper about software verification and validation of safe autonomous cars published on IEEE Access journal

21 January, 2021

We are glad to announce this new paper published on a top IEEE open access journal (Impact Factor:  3.7, Scimago Journal Rank: Q1 Computer Science).

The paper is co-authored by Nijat Rajabli, Francesco Flammini, Roberto Nardone and Valeria Vittorini and it is a literature review on the software Verification and Validation (V&V) of safe autonomous cars. The paper is a result of the outstanding job done by Nijat, a Linnaeus University student, during his project work for the course of Current Topics in Computer Science.

We believe that due to its quite extensive topic coverage, the paper can serve as a useful compendium for the many engineers and researchers who are starting to investigate those extremely current and challenging subjects related to the software safety of autonomous road vehicles.

Please find below more detailed information about the paper.

N. Rajabli, F. Flammini, R. Nardone and V. Vittorini, “Software Verification and Validation of Safe Autonomous Cars: A Systematic Literature Review,” in IEEE Access, vol. 9, pp. 4797-4819, 2021, doi: 10.1109/ACCESS.2020.3048047.

Abstract: Autonomous, or self-driving, cars are emerging as the solution to several problems primarily caused by humans on roads, such as accidents and traffic congestion. However, those benefits come with great challenges in the verification and validation (V&V) for safety assessment. In fact, due to the possibly unpredictable nature of Artificial Intelligence (AI), its use in autonomous cars creates concerns that need to be addressed using appropriate V&V processes that can address trustworthy AI and safe autonomy. In this study, the relevant research literature in recent years has been systematically reviewed and classified in order to investigate the state-of-the-art in the software V&V of autonomous cars. By appropriate criteria, a subset of primary studies has been selected for more in-depth analysis. The first part of the review addresses certification issues against reference standards, challenges in assessing machine learning, as well as general V&V methodologies. The second part investigates more specific approaches, including simulation environments and mutation testing, corner cases and adversarial examples, fault injection, software safety cages, techniques for cyber-physical systems, and formal methods. Relevant approaches and related tools have been discussed and compared in order to highlight open issues and opportunities.

Paper on Self-Adaptive Trust-Aware Decentralized Information Flow Control accepted at 1st IEEE International Conference on Autonomic Computing and Self-Organizing Systems

11 July, 2020

Congratulations to Charilaos, Narges and Jesper for their paper being accepted at the 1st IEEE International Conference on Autonomic Computing and Self-Organizing Systems (ACSOS 2020)!

Please find below additional information about their research.

Title: Self-Adaptive Trust-Aware Decentralized Information Flow Control
Authors: Charilaos Skandylas, Narges Khakpour, Jesper Andersson

Abstract:
Modern software systems and their corresponding
architectures are decentralized, distributed, and dynamic. As
a consequence, decentralized mechanisms are also required to
ensure security in such architectures. Decentralized Information
Flow Control (DIFC) is a mechanism to control information
flow in distributed systems. However, DIFC mechanisms require
the resolution of specific centralized control and trust issues. In
this paper, we propose an adaptive, trust-aware, decentralized
information flow approach that incorporates trust in DIFC for
decentralized systems. We employ decentralized feedback loops
to enable decentralized control and adaptive trust assignments.
In our approach, adaptivity mitigates two aspects of systems
dynamics that cause uncertainty: the ever-changing nature of
trust and the system openness. We formalize our trust-aware
DIFC model and instantiate two decentralized feedback loop
architectures to implement it. We discuss the design and implementation
considerations and evaluate the effectiveness of
adaptive trust-aware DIFC on a set of decentralized architectures
and a microservices-based system.

New workshop on Artificial Intelligence for RAILwayS (AI4RAILS) accepted at European Dependable Computing Conference

19 March, 2020

AI4RAILS – 1st International Workshop on Artificial Intelligence for RAILwayS

Organizers:
Workshop chairs: Stefano Marrone (University of Naples Federico II, Naples, Italy), Roberto Nardone (Mediterranean University of Reggio Calabria, Reggio Calabria, Italy)
Workshop series steering committee chairs: Francesco Flammini (Mälardalen University and Linnaeus University, Sweden), Valeria Vittorini (University of Naples Federico II, Naples, Italy)

The impact of Artificial Intelligence (AI) techniques on industry has been so disruptive that it gave rise to a new wave of research and applications. Several industries, mainly in logistics and manufacturing, have benefited significantly from AI adoption and this positive trend is planned to be kept in the future. Modern and future railways represent one of the fields in which AI is expected to have a significant impact in a medium to long term perspective, in order to get higher levels of automation. On the one hand, this opens for unprecedented scenarios for railway systems, but on the other hand, it also raises concerns regarding system dependability and new threats associated with a high level of autonomy. Therefore, the first step towards the adoption of AI in the railway sector is understanding to what extent AI can be considered reliable, safe and secure. In such a context, building upon the ongoing Shift2Rail project RAILS (Roadmaps for the AI integration in the raiL Sector), the aim of the 1st AI4RAILS workshop is to provide a forum for researchers, practitioners and business leaders to discuss and share new perspectives, ideas, technologies and solutions for an effective and dependable integration of AI techniques in rail-based transportation systems.
