WS1. Key Technology Enablers for 6G: AI and Intelligent Metasurfaces

Abstract: The stringent requirements set forth by demanding applications in 6G scenarios call for an extensive use of the available frequency bands (from sub-GHz to THz), sophisticated antenna designs, and advanced transmission techniques. Extending the knowledge of the propagation conditions in such future environments is essential to identify the fundamental and achievable performance limits.

Reconfigurable intelligent surfaces (RIS) and Reconfigurable holographic surfaces (RHS) will play a pivotal role in advanced 6G communication systems and networks. Specifically, RIS leverage smart radio surfaces with a high number of small antennas or metamaterial elements based on a programmable structure that can be used to control the propagation of electromagnetic waves. RHS with multiple input multiple output (MIMO) setup are composed of numerous metamaterial radiation elements integrated in a holographic pattern to generate beams with desirable directions.

The inherent complexity of these communication scenarios with smart environments powered by RIS, RHS, and the integration of novel functionalities such as integrated sensing and communications (ISAC) systems evidences the crucial role to be played by AI/ML for the design and optimization of an adaptive physical layer.

This workshop leverages, on the one hand, the work carried out by the INTERACT COST Action which is aimed at proposing novel designs and strategies for making future radio communication networks intelligent, as well as contributing to the creation of intelligent environments. And, on the other, it builds one the successful series of Workshops on Reconfigurable Intelligent and Holographic Surfaces for Communications and Networking, the fifth edition of which will take place at the IEEE MeditCom 2023.

This workshop will provide a forum for leading researchers from academia and industry to share their recent findings on how artificial intelligence can impact the physical and lower layer of 6G communication systems, with emphasis on RIS/RHS and integrated communications and sensing technologies.

Keynote 1: Towards an adaptive multifunctional disaggregated PHY based on cell-free massive MIMO and Open RAN

Speaker: Prof. Alister Burr (University of York)
Abstract: Next generation wireless systems will need to operate over a wide range of densities and scales to serve a wide variety of users and devices.  This has significant implications for the architecture of the infrastructure that will provide them, especially in terms of sustainability.  The concepts of Open RAN and Cell-free Massive MIMO (CFmMIMO) have come to the fore in recent years. Both involve a more distributed approach to the design of the radio access network (RAN), including the physical layer (PHY) - iIn fact disaggregation of the PHY is a core principle of Open RAN.  In this presentation we describe these concepts and discuss how they can be combined to provide an adaptive, multifunctional and sustainable approach to implement a next generation PHY.  We discuss also the role artificial intelligence and machine learning might play in such a network to improve both performance and sustainability, and also the crucial role of propagation research in the development of the approach.

Keynote 2: On the Degrees of Freedom and Optimal Waveforms of Holographic MIMO

Speaker: Prof. Marco Di Renzo (CentraleSupelec)
Abstract: Holographic MIMO is an emerging communication technology. The reference setup consists of two holographic surfaces (HoloSs) communicating with each other, with a HoloS being an electrically large antenna that is made of a virtually infinite number of radiating elements coupled with electronic circuits and a limited number of radio frequency chains. From a theoretical standpoint, the transmitting HoloS is capable of synthesizing any arbitrary surface current density and, hence, any radiated electromagnetic field, and the receiving HoloS is capable of sensing any impinging electromagnetic field. In this talk, we will discuss the theoretical foundation of Holographic MIMO with focus on the optimal multiplexing gain and communication waveforms.

WS2. First Int. Workshop on Cybersecurity in Healthcare and Medicine

Abstract: The First International Workshop on Cybersecurity in Healthcare and Medicine (CyHeMe) fosters discussion related to information security and cybersecurity resulting from the need to build secure, reliable and robust systems and services that not only support healthcare and medicine, but also foster well-being, encourage patients and the population in general to live according to healthy lifestyle recommendations, and address the specific safety needs of an aging population. This multidisciplinary workshop will bring together practitioners and researchers from relevant disciplines. Among other objectives, CyHeMe aims to: i) develop approaches that support multiple perspectives of information security and cybersecurity in healthcare and medicine; ii) develop or refine methods for achieving and raising cybersecurity of systems and services that promote well-being or health; and iii) identify open research and industry challenges, as well as validation objectives for proposed solutions.

Keynote 1: Emerging Digital Technologies and Risks: Where are the Security Issues when Using AI, Blockchain, and Telemedicine in eHealth?

Speaker: Assoc. Professor Martin Žagar, Ph.D., EMBA, Scientific Advisor in Computer Science, RIT (Rochester Institute of Technology) Croatia

Abstract: We are eyewitnesses of digital transformation in every aspect of our lives, when talking about emerging technologies in eHealth, such as Artificial Intelligence (AI), Blockchain, and Telemedicine, we talk about numerous benefits in terms of improving patient care, data management, and healthcare efficiency. However, these technologies also introduce specific cybersecurity risks that need careful consideration.

AI systems in eHealth often rely on vast amounts of patient data for training and decision-making. This data may include sensitive medical records or diagnostic images. The improper handling of this data, such as insufficient or improper encryption, could lead to data breaches and unauthorized access. AI systems can also be vulnerable to adversarial attacks, where malicious inputs are designed to deceive the AI algorithms, leading to inaccurate diagnoses or treatment recommendations, or may inherit biases present in the training data, leading to unequal treatment or misdiagnoses for certain patient groups. From the Blockchain perspective, smart contracts used in eHealth applications may contain vulnerabilities that could be identified by attackers to manipulate transactions or gain access to sensitive data. While blockchain is known for its security and immutability, privacy risks may arise when personal health information is stored on a public blockchain, potentially leading to de-anonymization. Blockchain applications in eHealth could also involve supply chain tracking of medical devices or identity management, which could be targeted by attackers to disrupt the healthcare supply chain or engage in identity theft. Finally, Telemedicine relies on secure networks for real-time communication between healthcare providers and patients. Weak encryption or vulnerabilities in communication protocols could lead to eavesdropping and unauthorized access to Telemedicine sessions. Patient data transmitted during Telemedicine sessions may be intercepted, compromising patient privacy and confidentiality.
