RSMS: Towards Reliable and Secure Metaverse Service Provision

Establishing and sustaining Metaverse service necessitates an unprecedented scale of resources. Some researchers consider the deployment of Metaverse service in a cloud-edge resource architecture, which can satisfy the escalating demand for Metaverse service resources while ensuring both high bandwidth and low latency. However, how to ensure the security and trustworthiness of resource nodes (RNs) in this architecture and thus ensure the reliability and security of Metaverse service is still a challenge. In this paper, we first propose a novel mechanism, named Reliable and Secure Metaverse Service (RSMS), to ensure Metaverse service reliability and security without sacrificing performance. RSMS consists of two protocols: (1) One is a blockchain-based lightweight mutual authentication protocol, which can assure the trustworthiness of heterogeneous Metaverse service RNs dynamically joining a Metaverse service resource pool and then guarantee the security of Metaverse service. (2) The other is a group authentication protocol used to form and maintain a stable and secure Metaverse service group composed of RNs, which ensures the reliability and enhances the security of Metaverse service. The reliability and security of Metaverse service under RSMS are thoroughly discussed, and also informal and formal security analysis are conducted. Additionally, we study the impact of RSMS on Metaverse service throughput, demonstrating its lightweight feature.
