Accepted Paper

Quantum-Resistant and Secure MQTT Communication
Lukas Malina (Brno University of Technology, Czechia), Patrik Dobias (Brno University of Technology, Czechia), Petr Dzurenda (Brno University of Technology, Czechia), Gautam Srivastava (Brandon University, Canada)
Full Paper
In this paper, we deal with the deployment of Post-Quantum Cryptography (PQC) in Internet of Things (IoT). Concretely, we focus on the MQTT (Message Queuing Telemetry Transport) protocol that is widely used in IoT services. The paper presents our novel quantum-resistant security proposal for the MQTT protocol that supports secure broadcast. Our solution omits using TLS with the handshake causing delay and is suitable for sending irregular short messages. Finally, we show how our solution can practically affect concrete use cases by the performance results of the proposed solution.

Identification of industrial devices based on payload
Ondrej Pospisil (Brno University of Technology, Faculty of Electrical Engineering and Communication, Department of Telecommunication, Czechia), Radek Fujdiak (Brno University of Technology, Faculty of Electrical Engineering and Communication, Department of Telecommunication, Czechia)
Full Paper
The identification of industrial devices based on their behavior in network communication is important from a cybersecurity perspective in two areas: attack prevention and digital forensics. In both areas, device identification falls under asset management or asset tracking. Due to the impact of active scanning on these networks, particularly in terms of latency, it is important to take care in industrial networks to use passive scanning. For passive identification, statistical learning algorithms are nowadays the most appropriate. The aim of this paper is to demonstrate the potential for passive identification of PLC devices using statistical learning based on network communication, specifically the payload of the packet. Individual statistical parameters from 15 minutes of traffic based on payload entropy were used to create the features. Three scenarios were performed and the XGBoost algorithm was used for evaluation. In the best of the scenarios, the model achieved an accuracy score of 83% to identify individual devices.

Full Paper
In the era of growing threats posed by the development of quantum computers, ensuring the security of electronic services has become fundamental. The ongoing standardization process led by the National Institute of Standards and Technology (NIST) emphasizes the necessity for quantum-resistant security measures. However, the implementation of Post-Quantum Cryptographic (PQC) schemes, including advanced schemes such as threshold signatures, faces challenges due to their large key sizes and high computational complexity, particularly on constrained devices. This paper introduces two microcontroller-tailored optimization approaches, focusing on enhancing the DS2 threshold signature scheme. These optimizations aim to reduce memory consumption while maintaining security strength, specifically enabling the implementation of DS2 on microcontrollers with only 192 KB of RAM. Experimental results and security analysis demonstrate the efficacy and practicality of our solution, facilitating the deployment of DS2 threshold signatures on resource-constrained microcontrollers.

DECEPTWIN: Proactive Security Approach for IoV by Leveraging Deception-based Digital Twins and Blockchain
Mubashar Iqbal (University of Tartu, Institute of Computer Science, Estonia), Sabah Suhail (Queen's University Belfast, United Kingdom), Raimundas Matulevičius (University of Tartu, Institute of Computer Science, Estonia)
Full Paper
The proliferation of security threats in connected systems necessitates innovative approaches to enhance security resilience. The Internet of Vehicles (IoV) presents a rapidly evolving and interconnected ecosystem that raises unprecedented security challenges, including remote hijacking, data breaches, and unauthorized access. Digital Twin (DT) and blockchain-based deception can emerge as a promising approach to enhance the security of the IoV ecosystem by creating a secure, realistic, dynamic, and interactive deceptive environment that can deceive and disrupt malicious actors. In accordance with this, we propose a proactive security approach for IoV by leveraging DECEPtion-based digiTal tWins and blockchaIN (DECEPTWIN) that entails hunting for security threats and gaps in IoV security posture before an incident or breach occurs.

Secure and Privacy-Preserving Car-Sharing Systems
Lukas Malina (Brno University of Technology, Czechia), Petr Dzurenda (Brno University of Technology, Czechia), Norbert Lövinger (Brno University of Technology, Czechia), Ijeoma Faustina Ekeh (University of Tartu, Estonia), Raimundas Matulevicius (University of Tartu, Estonia)
Full Paper
With increasing smart transportation systems and services, potential security and privacy threats are growing. In this work, we analyze privacy and security threats in car-sharing systems, and discuss the problems with the transparency of services, users' personal data collection, and how the legislation manages these issues. Based on analyzed requirements, we design a compact privacy-preserving solution for car-sharing systems. Our proposal combines digital signature schemes and group signature schemes, in order to protect user privacy against curious providers, increase security and non-repudiation, and be efficient even for systems with restricted devices. The evaluation of the proposed solution demonstrates its security and a practical usability for constrained devices deployed in vehicles and users' smartphones.

DDS Security+: Enhancing the Data Distribution Service With TPM-based Remote Attestation
Paul Georg Wagner (Fraunhofer IOSB, Germany), Pascal Birnstill (Fraunhofer IOSB, Germany), Tim Samorei (Karlsruhe Institute of Technology, Germany), Jürgen Beyerer (Karlsruhe Institute of Technology, Germany)
Full Paper
The Data Distribution Service (DDS) is a widely accepted industry standard for reliably exchanging data over the network using a publish-subscribe model. While DDS already includes basic security features such as participant authentication and access control, the possibilities of leveraging Trusted Platform Modules (TPMs) to increase the security and trustworthiness of DDS-based applications have not been sufficiently researched yet. In this work, we show how TPM-based remote attestation can be effectively integrated into the existing DDS security architecture. This enables application developers to verify the code integrity of remote DDS participants during the operation of the distributed system. Our solution transparently extends the DDS secure channel handshake, while cryptographically binding the established communication channels to the attested software stacks. We show the security properties of our proposal by formally verifying the resulting remote attestation protocol using the Tamarin theorem prover. We also implement our solution as a fork of the popular eProsima FastDDS library and evaluate the resulting performance impact when conducting TPM-based remote attestations of DDS applications.

Full Paper
The practicality of IoT is becoming more and more apparent, including smart homes, autonomous vehicles, environmental monitoring, and the internet everywhere. The rapid spread has also lead to a large number of cybersecurity threats such as Denial of Service attacks, Information stealing attacks, and so on. Machine learning techniques have been proved to be a valuable tool for detecting network threats in IoT. Feature selection has been proven to overcome excessive features of the dataset in the feature reduction phase, which helps reducing computational costs while still keeping the generalization of machine learning model. However, most existing studies have only focused on using a limited number of methods for feature selection (typically one). Moreover, there is very few research evaluating which technique is the most effective across various datasets, and can be used as a best choice method in general. Therefore, this work aims to test 5 feature selection techniques: Random Forest, Recursive Feature Elimination, Logistic Regression, XGBoost Regression and Information Gain. The new dataset (CIC-IoT 2023) is applied to evaluate the performance of those feature selection methods. This study also performs IoT attacks detection based on 5 Machine learning models: Decision Tree (DT), Random Forest (RF), k-Nearest Neighbours (k-NN), Gradient Boosting (GB) and Multi-layer Perceptron (MLP). We look at the computational metrics such as accuracy, precision, recall and F1-score to evaluate the performance of each technique over three actual datasets. Overall, the research shows that Recursive Feature Elimination stands out as the top feature selection method, achieving the average accuracy of 95.55%, as well as the highest accuracy of 99.57% when being used in combination with RF in case of 30 selected features.
