Cyberattack Detection in Vehicles using Characteristic Functions, Artificial Neural Networks, and Visual Analysis
Abstract
The connectivity of autonomous vehicles induces new attack surfaces and thus the demand for sophisticated cybersecurity management. Thus, it is important to ensure that in-vehicle network monitoring includes the ability to accurately detect intrusive behavior and analyze cyberattacks from vehicle data and vehicle logs in a privacy-friendly manner. For this purpose, we describe and evaluate a method that utilizes characteristic functions and compare it with an approach based on artificial neural networks. Visual analysis of the respective event streams complements the evaluation. Although the characteristic functions method is an order of magnitude faster, the accuracy of the results obtained is at least comparable to those obtained with the artificial neural network. Thus, this method is an interesting option for implementation in in-vehicle embedded systems. An important aspect for the usage of the analysis methods within a cybersecurity framework is the explainability of the detection results.

Performative Framework and Case Study for Technology-Enhanced Learning Communities
Abstract
This paper employs the overarching concept of communities to express the social contexts within which human creativity is exercised and learning happens. With the advent of digital technologies, these social contexts, the communities we engage in, change radically. The new landscape brought about by digital technologies is characterized by new qualities, new opportunities for action, new community affordances. The term onlife is adopted from the Onlife Manifesto and used to distinguish the new kind of communities brought about by the modern digital technologies, the onlife communities. Design principles are presented to foster such communities and support their members. These principles constitute a framework that emphasizes the concept of performativity, i.e. knowledge is based on human performance and actions done within certain social contexts, rather than development of conceptual representations. To demonstrate the use of the framework and the corresponding principles, the paper presents how they can be used to analyze, evaluate and reframe a concrete system addressing creativity and learning in the field of cultural heritage (history teaching and learning). One of the most significant results is the adoption of principles that facilitate students’ engagement in rich learning experiences moving from the role of end-user towards the role of expert-user with the support of so called maieuta-designers. The result of this process is the use of the studied software not only to consume ready-made content but the creation of new, student generated content, offering new learning opportunities to the students. As the evaluation shows, these new learning opportunities enable students to develop a deeper understanding of the topics studied.
