Dynamic authentication protocols for advanced security in federated metaverse systems

Abstract

Metaverse is a dynamic virtual reality-based environment that is rapidly revolutionizing digital engagement. The Metaverse is propelled by the integration of technologies like blockchain, augmented reality, virtual reality, and artificial intelligence. The Metaverse is quickly increasing in acceptance as a fully immersive cyberspace for work, entertainment, and socializing. After the idea of the Metaverse, an evolution of the concept is envisioned known as the Federated Metaverse. The idea of the Federated Metaverse presents it as a digital domain that is dynamically organized as an interconnected network of separately managed worlds known as Metaworlds. These several realms function independently within the Federated Metaverse based on specific purposes, in contrast to conventional metaverse models, and are each subject to their own set of laws, regulations, and user experiences. While users traverse through these Metaworlds in this federated architecture, identity verification becomes critical to ensure appropriate permission and authentication that comply with the unique regulations and goals of each Metaworld. As the concept of this virtual universe is expected to become increasingly integrated into our daily lives, it is imperative to address the security concerns that may come up while interacting with these digitally created worlds. To counter these possible security challenges, the paper proposes a dynamic authentication model crafted for the concept of the Federated Metaverse. The goal is to design a comprehensive authentication model that can support any algorithm based on specific requirements, using multiple factors to reinforce security. The proposed model will ensure a versatile and robust authentication process. The main emphasis of the model is to bolster user privacy and security in general to ensure a solid and reliable basis in this changing digital environment all while keeping usability in mind. The user-centered secured authentication framework will prioritize usability and simplicity of interaction to enhance the overall user experience and security within the Metaverse.
