“…SDN enables the flexible and scalable management of large-scale metaverse networks via the separation of the control plane and data plane. In SDN-based metaverse, the physical devices and resources are managed by a logically centralized controller using a standardized interface such as OpenFlow, thereby virtualized computation, storage, and bandwidth resources can be dynamically allocated according to realtime demands of various sub-metaverses [36]. Besides, IoT is a network of numerous physical objects that are embedded with sensors, softwares, communication components, and other technologies with the aim to connect, exchange, and process data between things, systems, clouds, and users over the Internet.…”

Metaverse, as an evolving paradigm of the nextgeneration Internet, aims to build a fully immersive, hyper spatiotemporal, and self-sustaining virtual shared space for humans to play, work, and socialize. Driven by recent advances in emerging technologies such as extended reality, artificial intelligence, and blockchain, metaverse is stepping from science fiction to an upcoming reality. However, severe privacy invasions and security breaches (inherited from underlying technologies or emerged in the new digital ecology) of metaverse can impede its wide deployment. At the same time, a series of fundamental challenges (e.g., scalability and interoperability) can arise in metaverse security provisioning owing to the intrinsic characteristics of metaverse, such as immersive realism, hyper spatiotemporality, sustainability, and heterogeneity. In this paper, we present a comprehensive survey of the fundamentals, security, and privacy of metaverse. Specifically, we first investigate a novel distributed metaverse architecture and its key characteristics with ternary-world interactions. Then, we discuss the security and privacy threats, present the critical challenges of metaverse systems, and review the state-of-the-art countermeasures. Finally, we draw open research directions for building future metaverse systems.

“…To achieve seamless and all-encompassing network access to metaverse services in 6G, the space-air-ground integrated network (SAGIN) 41 is a potential trend. The use of software-defined networking (SDN) 42,43 can also make it possible to run massive metaverse networks in a flexible and scalable manner. In ubiquitous computing, as depicted in Figure 4, the cloud-edge-end computing 44 orchestrates heterogeneous edge computing infrastructures with highly scalable cloud infrastructures for increased QoE.…”

The next step of digital development is the metaverse, which has the potential to drastically alter how people use technology and expand the range of services available beyond conventional systems that can be accessed online. As the efficiency, performance, and quality of service access reach their peak levels, the focus has shifted to the user experience. Due to this, there is an increasing demand for more involved and thorough customer service, and service providers are willing to increase their present standards. Consumers are genuinely asking for tactile and immersive elements in their digital interfaces, but these features can only be made possible by the metaverse's potentially futuristic subfields of virtual reality (VR), augmented reality (AR), mixed reality (MR), and extended reality (XR). However, the metaverse may not be widely used due to significant security and privacy issues either from underlying technology or produced by the new digital environment. A variety of fundamental problems, such as scalability and interoperability, can arise in terms of ensuring security for the metaverse because of the metaverse's inherent properties, such as immersive realism, sustainability, and heterogeneity. In this survey, we propose a hypothetical meta‐stack framework to understand the various components in the realm of metaverse and then provide wide‐ranging insights on the most recent development in metaverse realm in the context of cutting‐edge technologies, security vulnerabilities and preventive measures specific to the metaverse and the research challenges pertaining to metaverse.
