Tutorial Title:
Metasource-Based Physical Layer Security for Future Wireless Networks


Date: Monday June 19, 2023 @ 10:00 am – 1:00 pm


The physical-layer security (PLS) is a promising concept to complement the cryptographic technologies at upper layers in wireless networks. Various channel-based approaches, e.g., secret-key extraction, directional modulation, and artificial-noise injection, have been conceived to exploit wireless channel characteristics in providing PLS.

Recently, legitimate channel-gain-mapped sources have been developed to constitute a novel technology of the physical-layer secret key generation, referred to as metasource-based secret key (MBSK).  In contrast to the channel-based approaches, the MBSK technology not only promotes the actual realisation of the PLS concept but also induces green communications for future wireless networks.

This tutorial introduces the MBSK technology through discussing its design principles, the latest advantages, the challenges, and the road ahead in the research.  Our hope is to facilitate researchers who might have interests in the PLS concept would like to kick-start their understanding of recently developed techniques in the MBSK realm.

  1. Information-theoretic PLS models

Tutorial Title:
Digital Twin for 6G: Taxonomy, Research Challenges, and the Road Ahead

DateMonday June 19, 2023 @ 10:00 am – 1:00 pm


6G networks require the stringent quality-of-service (QoS) requirements in terms of very high data rate, ultra-high success reception rate, and very low latency. Supported by high QoS wireless communications, digital twin has become a game-changing technology in many applications including smart city, manufacturing, automotive, gaming, entertaining, and climate resilience. Edge computing-based wireless ultra-reliable and low-latency communications (URLLC) in 6G has been considered as a key technique to realise the full potential of digital twin. At the same time, Open RAN (O-RAN) Alliance is actively working towards transforming the radio access networks (RAN) industry in a way that both its physical and logical RAN products will be more open, smarter, interoperable, and scalable than contemporary deployments. In this way will be possible to address the inevitable traffic overload of the current networks caused by an expected mobile data traffic explosion, which according to ITU-R will be up to 5016 exabyte per month. Also in this context, the novel and recent concept of DT will play an important key role. Indeed, empowered with artificial intelligence (AI) and machine learning (ML) based mechanisms, DT will support the development of key functionalities of O-RAN architecture like non-real-time (Non-RT) and near real-time (Near-RT) RAN intelligent controller (RIC) modules, used to perform powerful AI aided network performance optimisations. This tutorial discusses a joint communications and computation design of URLLC multi-tier computing in 6G that supports digital twin networks, as well as a possible DT based approach for the implementation of both Non-RT and Near RT modules in O-RAN. Fundamental requirements, but also enabling technologies, visions, and future challenges will be discussed.

Advancing the Frontiers of Semantic Communication: A Comprehensive Exploration of Techniques, Applications, and Future Prospects


Date: Monday June 19, 2023 @ 3:00 – 6:00 pm


Nowadays, semantic communication is gaining significant momentum due to its potential to revolutionize the existing data-driven communication infrastructure, transforming it into a more universally intelligent, goal-oriented, and semantically-informed networking system. The adoption of semantic communication promises to enhance the efficacy of communication systems by enabling them to comprehend and process contextual meanings, leading to more relevant and personalized exchanges between entities. This transformative capability is a crucial factor in shaping the future of communication systems, as it unlocks the potential for more sophisticated, automated, and efficient interactions in diverse domains such as e-commerce, healthcare, and education. Consequently, the adoption of semantic communication represents a promising avenue for research and development, with wide-ranging implications for advancing intelligent systems.

In this tutorial, our aim is to provide a comprehensive understanding of semantic communications. We begin by answering the “what” and “why” questions in semantic transmissions before delving into the corresponding ecosystems, which include theories, metrics, datasets, and toolkits. We also present a taxonomy for research directions in this relatively nascent field. Additionally, we explore various machine learning and distributed learning strategies that can be employed to enhance semantic communications and facilitate effective knowledge sharing. We will focus on key techniques such as representation learning, knowledge graph construction, reinforcement learning algorithms, and transfer learning techniques. During this tutorial, we will discuss how these methods enable machines to better comprehend human communications, effectively participate in semantic information exchanges, and foster greater collaboration between humans and machines. As a case study, we will delve into implementing these strategies in real-world applications, demonstrating their ability to promote more efficient and goal-oriented communications across diverse domains. The tutorial is concluded with a detailed discussion of novel perspectives and future directions for semantic communications, with a particular emphasis on deep learning-enabled semantic communication systems.

 Empowering Decentralized Metaverse Security


Date: Monday June 19, 2023 @ 3:00 – 6:00 pm


The metaverse is a virtual world that is being increasingly explored as a new frontier for communication, collaboration, and commerce. However, as the metaverse evolves, trust and interoperability issues have emerged as significant challenges that must be addressed.

Trust is a critical issue in the metaverse because it is a virtual world where users interact with one another and engage in various activities. Without trust, users may be hesitant to participate in the metaverse, which would limit its growth and development. Interoperability is also a significant challenge in the metaverse. The metaverse comprises many different virtual worlds, each with its unique set of rules and protocols. These virtual worlds may not be able to communicate or interact with one another, making it difficult for users to move between them and participate in the full range of activities that the metaverse has to offer. Therefore, the goal of this tutorial is to:

  1. To provide an overview of the current trust and interoperability issues in the metaverse and their impact on the growth and development of the virtual world.
  2. To explain the various strategies and technologies that can be used to address trust and interoperability issues in the metaverse.
  3. To demonstrate how to implement these strategies and technologies in practical examples and case studies to simulate the Metaverse environment.
