In the field of Cooperative Intelligent Transport Systems (C-ITSs), the traditional approach to testing often emphasizes technological parameters, leaving the validation of message content insufficiently addressed. Since the content of these messages is crucial for the correct functioning of C-ITS, this article demonstrates the potential for automated evaluation of C-ITS message content against relevant standards. It leverages our novel tools, Karlos and C-ITS SIM, to facilitate this process. Through detailed laboratory testing and data analysis, the study showcases the effectiveness of these automated solutions in enhancing the accuracy and reliability of message content validation.

In the era of Industry 4.0 and the rise of smart cities, the integration of industrial and telematics systems has become increasingly prevalent, revolutionizing the way we manage and optimize processes. These systems, which encompass everything from manufacturing plants to transportation networks, rely heavily on interconnected devices and data exchange to enhance efficiency and functionality. However, this interconnectedness also brings about a heightened level of vulnerability to cyber threats, emphasizing the critical importance of robust cybersecurity measures. This article specifically delves into a case study of a selected Denial of Service (DoS) cyber attack on industrial networks, highlighting the critical need for such cybersecurity solutions. Current software was utilized to simulate an attack. The results are provided using the software that was created specifically for this type of task, demonstrating the practical application and effectiveness of these cybersecurity measures in real-world scenarios.

With the increasing complexity of cyber attacks, traditional methods for anomaly detection in cybersecurity are insufficient, leading to the necessity of integrating deep learning and neural network approaches. This paper presents a comparative analysis of the most powerful deep learning methods for such anomaly detection. We analysed existing datasets for syslog and dataflow, compared several preprocessing methods and identified their strengths and weaknesses. Additionally, we trained and evaluated several deep learning models to provide a comprehensive overview of the current state-of-the-art in cybersecurity. The CNN model achieves excellent results, with 0.999 supervised and 0.938 semi-supervised F1-score in syslog anomaly detection on the BGL dataset and 0.985 F1-score in dataflow anomaly detection on the NIDS dataset. This research contributes to the field of cybersecurity by aiding researchers and practitioners in selecting effective deep-learning models for robust real-life anomaly detection systems. Our findings highlight the reusability of these models in real-life systems.

The article presents a novel algorithm for merging Bayesian networks generated by different methods, such as expert knowledge and data-driven approaches, while leveraging a symmetry-based approach. The algorithm combines the strengths of each input network to create a more comprehensive and accurate network. Evaluations on traffic accident data from Prague in the Czech Republic and accidents on railway crossings demonstrate superior predictive performance, as measured by prediction error metric. The algorithm identifies and incorporates symmetric nodes into the final network, ensuring consistent representations across different methods. The merged network, incorporating nodes selected from both the expert and algorithm networks, provides a more comprehensive and accurate representation of the relationships among variables in the dataset. Future research could focus on extending the algorithm to deal with cycles and improving the handling of conditional probability tables. Overall, the proposed algorithm demonstrates the effectiveness of combining different sources of knowledge in Bayesian network modeling.

With the increasing number of cybersecurity attacks and their increasing complexity, it is necessary to adapt the detection methods to be able to prevent such attacks. The replacement of traditional detection methods based on machine learning with more advanced deep learning and neural network approaches is the crucial step for this. In this paper, we present a comparative analysis of different deep learning models for anomaly detection in syslog. We analysed existing datasets for system logs and compared several preprocessing methods. We evaluated different deep learning models on those preprocessed datasets to provide a comprehensive overview of the current state-of-the-art in cybersecurity. We achieved the best results with the CNN model with 0.999 F1-score on the BGL dataset showing the great potential in such techniques for the real-life models monitoring the system and detecting anomalies.

This paper introduces the issue of personal and non-personal data in autonomous vehicles. Its main objective is to provide a procedure for determining the processed and retained data, to explain the current legal regulation that must be met, and to propose appropriate recommendations for each data category. Current law (and the regulatory framework which it has produced) generally distinguishes between two basic types of data, i.e. non-personal data and personal data. The phenomenon that a combination of several pieces of non-personal data may, under certain circumstances2, result in processing of personal data, which is subject to significant regulation, is not limited solely to the field of autonomous mobility. This paper deals with data classification in autonomous vehicles, focusing on the challenging cases of non-personal data that can turn into personal data. The initial stage involves identifying the data to be processed, followed by the classification of the identified data. Based on this classification, relevant legal obligations and recommendations are described. The primary objective of this article is to provide guidance to data administrators (or, to use the terminology of data protection laws, data controllers) in autonomous mobility, enabling them to identify data and take appropriate measures to ensure compliance with legal regulations. The ultimate aim is to ensure that data controllers adhere to legal requirements, a goal that is critical for all data controllers. Beyond that, this article should be relevant also for other stakeholders in the autonomous mobility ecosystem, such as vehicle manufacturers and their suppliers, software application and service providers, and others.

owadays, there are limited capabilities to limit the speed of vehicles or to stop them. The current methods used within communication on the roads use informative messages that are not influencing the movement of the vehicles. Currently, to limit the speed of the vehicles only destructive and invasive methods are used. These methods can lead to threats to the health and lives involved in road traffic. In this paper, we designed and verified a unique system for influencing the speed of vehicles. The test-bed consists of two vehicles that contain COHDA-MK6 OBU devices and a mobile application for managing the vehicles. The verification for the developed system was performed on a race circuit in the Czech Republic with the cooperation of the Czech police. During the testing, two vehicles were going almost 100 km/h and the security forces in a police vehicle successfully stopped the other car. The process for stopping the car consists of the mobile application that sends the C-ITS (Cooperative Intelligent Transport Systems) message that is transmitted to the target vehicle. In this paper, we successfully verified in practice on a race circuit that the proposed system to limit the speed of vehicles is working.

Currently, the number of vehicles in road traffic is increasing, which enhances the variety of traffic situations and needs related to road traffic and safety. A cooperative intelligent transport system (C-ITS) can improve road safety and benefit drivers and traffic participants. The C-Roads specification defines many different use cases for informing road vehicles about speed limits, impending danger, road work, signalized intersections, and more. In this article, we propose a new use case targeting the need for Integrated Rescue System services to slow down or stop selected vehicles that are violating rules. Unlike most use cases in C-Roads, in our case, it is not enough to only notify the driver’s vehicle; it must also be slowed down or stopped completely. This intervention requires addressing issues from a technical and a procedural/legal point of view. In this work, we define the use case itself, following the templates of the specification in C-Roads. Then, we discuss the issues in terms of secure communication between vehicles and privacy. We also analyze existing protection security techniques against typical cybersecurity attacks and privacy countermeasures. Next, we propose a system architecture concerning appropriate C-ITS messages and communication between vehicles and present an onboard diagnostics simulator implementing the proposed architecture for the core needs of a given use case. Furthermore, we create a practical demonstrator of our proposal based on real vehicle components. Finally, we discuss open research questions and the ongoing development of the use case before the application on the Internet of Vehicles.

Nowadays, when new technologies are being developed and people are looking for smart solutions, the field of automation and digitization grows faster and faster. The demand on the telecommunications is increasing in economy, healthcare as well as in the transportation. The transportation systems are facing the challenge of smart infrastructure, autonomous vehicles, and its connectivity. The requirements for these systems lie mainly in safety, interoperability and sustainability, especially in the area of cooperative transport systems (C-ITS). This article focuses on a possible approach to test and evaluate C-ITS, threats that have to be ruled out in future, possibilities to ensure connectivity among the vehicles and infrastructure in C-ITS. For these purposes, Czech Technical University in Prague (CTU) and its laboratory Certilab develop special procedures based mainly on the C-ITS SIM tool. This tool ensures validation and verification of C-ITS messages and its interoperability among all equipment. This paper also reviews the already developed applications and proposal of the functionalities that should be implemented for the testing as well as the examples of real usage of the developed tool in testing the communication of C-ITS messages.

In the area of smart cities, great emphasis is placed on many different fields such as energetics, information systems, and transportation. All of these should lead to a simplification of life thanks to smart technologies. If we talk about the transportation field, the main issues related to this area are safety, traffic efficiency, or the environment. Another condition is the successful acceptance of any new technology by its users. Cooperative systems prove to be a suitable solution for these issues, especially in urban areas. Today, pilot implementations of cooperative systems in European countries are being carried out. However, before they are put into full operation, they need to be tested, evaluated, and assessed. This article focuses on the latter two points, i.e., evaluation and assessment of the cooperative systems. For this purpose, a methodology was created, which describes the procedure chosen in the evaluation and assessment of cooperative systems in the Czech Republic and a demonstration of its use by example. The methodology is focused on three main areas, which in this case are functional evaluation, user acceptance, and impact assessment. For the area of user acceptance, the main source was questionnaires, impact assessment relied on measured data while functional evaluation was based on discussions with the drivers, evaluating the cooperative systems, the measured data, and the expert observations. All collected and measured data were then processed and some of the results of the evaluation of the selected service are presented at the end of this article.

Nowadays, when a traffic flow increases extremely and cities are more and more congested by vehicles, the information about unexpected events (use-cases) occurred during travels has a big added value. Some of the use-cases are currently defined and can be directly sent to a driver via C-ITS messages. This is crucial in the field of smart cities because there is an effort to reduce emissions, to decrease traffic accidents and make traffic safer, fluent and efficient. Before the whole C-ITS system will be deployed, there is a need to evaluate itself. This paper provides general information about a model of the system and its parts as well as methods for testing and technical evaluation primary based on the log-analysis of the C-ITS communication.

Cooperative systems play an important role in the field of telematics and automotive industry and they have a huge potential to continuously grow. To ensure proper functioning it is necessary to deal with telecommunication solutions being able to support relevant information dissemination within vehicles networks. There are many different approaches to networking and information distribution in VANET networks. Different approaches can meet partial requirements; however, none of the existing approaches can offer solution being able to meet all key requirements generated by the real traffic. The conclusions of our studies and simulations so far show that an appropriate option must combine Geocast based routing type with centrally operated cluster based support. Such approach also well fits with available telecommunications system architecture applicable for VANET solutions.

Guaranteed quality of telecommunication service and wide area coverage are typical requirements of the ITS (Intelligent Transport Systems) applications. Extensive range of wireless data services with reasonable coverage is offered by public wireless data services providers, however, mostly no guaranteed relevant range of quality and security has been available. As ITS services require cost-effectively solution, as well, requirements can be resolved by seamless switched combination of public and private services selected in accordance to agreed criteria realized by implemented decision processes. Specific situation is identified in case of the C2I (Car to Infrastructure) and C2C (Car to Car) communication namely if the vehicle on board unit is interconnected with the vehicle CAN (Controlled Area Network) based network. Such dynamically developing telecommunications solution touching public networks significantly increase potential of dangerous intruders´ attacks. That is also the main reason why relevant telecommunications security support is understood as one of the crucial part of the ITS telecommunications solution. System security is discusses in detail in this paper and security performance indicators are defined in context of already adopted telematics and telecommunications performance indicators.

Guaranteed selected quality of telecommunication service and wide area coverage are typical requirements of the ITS (Intelligent Transport Systems) applications. Extensive range of wireless data services with reasonable coverage is provided by public wireless services operators, however, mostly no guaranteed relevant range of quality and security is available. ITS services require cost-effectively solution which can be resolved by combination of the “core” public solution with the other public as well as private services where and when it is needed. Such approach requires implementation of the relevant flexible system architecture supported by the efficient decision processes. ITS specific service security requirements would not underestimated, as well. Special situation is identified in case of the C2I (Car to Infrastructure) and C2C (Car to Car) communication namely if the vehicle on board unit is interconnected with the vehicle CAN (Controlled Area Network) based network. Such configurations significantly increase potential of dangerous intruders´ attacks. Probability of the critical hazards appearances grows if the ITS data are accessible in the wide area networks. That is also the main reason why relevant telecommunications security support is understood as one of the crucial part of the ITS telecommunications solution.

Intelligent Transport Services expect availability of the secure seamless communications solutions typically covering widely spread areas. Different ITS solutions require different portfolio of telecommunications service quality. These parameters have to correspond with ITS service performance parameters required by specific service. Even though quite extensive range of public wireless data services with reasonable coverage are provided, most of them are provided with no guaranteed quality and security. ITS requirements can be in most parameters easier reached if multi-path communications systems are applied core solution is combined with both public as well as private ones where and when it is needed. Such solution requires implementation of relevant flexible system architecture supported by the efficient decision processes. This paper is concentrated the telecommunications security issues relevant to the ITS wide area networking. Expected level of security varies in dependence on relevant ITS service requirements. Data volumes transferred both in private data vehicle on board networks as well as between vehicles and infrastructure (C2I) or other vehicles (C2C) progressively grow. Such trend upsurges the fatal problems appearance probability in case security of the wide area networks is not relevantly treated. That is reason why relevant communications security treatment becomes crucial part of the ITS solution. Besides of available “off shelf” security tools we present solution based on non-public universal identifier with dynamical extension (time and position dependency as an autonomous variables) and data selection according to actor role or category. Presented results were obtained within projects e-Ident1, DOTEK2 and SRATVU3.

This paper is primarily concentrated on design of the telecommunications solutions for the ITS security requirements quantified by specific security performance indicator. Car to Infrastructure and Car to Car communication interconnected with the vehicle on board data communication network based on the CAN (Controlled Area Network) bus increase potential of the appearance of the intruder attacks, namely, if the security of the wide area networks is not carefully enough treated. Probability of hazards appearances principally grow if such networks are integrated in the dynamically organized wide area ones. Besides of standard security tools solution based on the non-public universal identifier with dynamical extension and data availability control according to the actor role or category is presented.

Guaranteed telecommunication service selected quality and defined area coverage are typical requirements of the ITS applications. Limited range of wireless data services with reasonable coverage is provided by public wireless services operators, and, mostly no guaranteed relevant range of service quality and security is available. Solution can be resolved based on combination of the core solution with the other public as well as private services where and when it is needed. ITS specific service security requirements cannot be underestimated, so that tolerance range of security performance parameters must be guaranteed by service providers combined with specific security approached implemented on ITS service level.

Intelligent Transport Services (ITS) applications require availability of the wireless seamless secure communications solutions with selectable services quality and wide-area coverage. Authors present L3 alternative to CALM solution with adaptive classifications processes applied instead of PBM ones. Such approach can be efficiently implemented specifically if there is available deep understanding of applied technologies. Requirements on the representative system performance indicators and their tolerance range should be so carefully identified. Paper includes results of authors' laboratory study of three most widely spread data services which as basis new system approach implementations.

Intelligent Transport Systems(ITS) solutions require availability of the secure seamless communications solutions and coverage of the widely spread areas is typically demanded. Different solutions require different levels of the teleco service quality. These parameters are linked with ITS service performance parameters used to quantify services parameters. Even though quite extensive range of wireless data services with reasonable coverage are provided by public teleco providers practically all services are provided with no guaranteed data service quality and security. ITS requirements can be better resolved if typically used public solution can be combined with both other public and private services where and when it is needed. Such solution requires implementation of the relevant flexible system architecture supported by the efficient decision processes. This paper is, however, primarily concentrated on the teleco security issues quantified by specific security performance parameter.

Intelligent Transport Services (ITS) applications require availability of the wireless seamless secure communications solutions with selectable services quality and wide-area coverage. Efficient decision processes must be implemented in the appropriate flexible seamless routing/switching structures. Generally recommended solution has been described in series of documents generated by ISO/CEN working group TC204/278, WG16.1 known as CALM family of standards. Authors present L3 alternative solution with adaptive classifications processes applied instead of PBM ones. Such approach can be efficiently implemented specifically if there is available deep understanding of applied technologies. Paper includes results of authors' laboratory study of three most widely spread data services which can be understood as basis for the "CALM ideas" based system implementations.

Communication is very important part of Intelligent Transport Systems chain to have reliable and secure data transmission between elements within the ITS architecture. One of the ways to achieve a more reliable ITS applications is to make them independent from the communication and solve this part separately. This is the idea of CALM-based system which covers more access communication solutions. But if there is a necessity to have reliable data transmission, the communications access technology has to be described. This paper focuses on the evaluation of WiFi as suitable communication technology for CALM-based system usage based on laboratory measurement of WiFi properties.
