The metaverse provides a virtual world with many social activities that parallel the real world. As attracts more attention, importance of security and privacy preservation is increasing significantly. In metaverse, users have capability to create various avatars, which can be exploited deceive or threaten others, leading internal issues. Additionally, attempting access are susceptible external threats since they communicate service providers through public channels. To address these challenges, we propose an authentication scheme using blockchain, decentralized identifier, verifiable credential enable perform secure identity verification without disclosing sensitive information providers. Furthermore, proposed approach mitigates concerns associated management personal by enabling prove necessary independently relying on We demonstrate resistant malicious attacks performing analyses, such as AVISPA simulation, BAN logic, real-or-random (ROR) model. also show performance our better suited for environment providing greater efficiency when compared competing schemes.

Recently, the Digital Twin (DT) technology has procured a lot of attention because its applicability in manufacturing and space industries. The DT environment involves formation clone tangible object to perform simulations virtual space. combination conceptual development, predictive maintenance, real-time monitoring, simulation characteristics increased utilization different scenarios, such as medical environments, healthcare, industries, aerospace, etc. However, these utilizations have also brought serious security pitfalls deployment. Towards this, several authentication protocols with privacy features for environments been proposed. In this article, we first review recently proposed two-factor protocol that utilizes blockchain technology. analyzed scheme is unable offer desirable cannot withstand various attacks like offline password-guessing attack, smart card stolen anonymity property, known session-specific temporary information attack. We demonstrate an attacker can impersonate protocol's legal user, owner, cloud server. To mitigate loopholes, devise effective three-factor privacy-preserving environments. work demonstrated be secure by performing informal analysis, formal analysis using widely recognized Burrows-Abadi-Needham (BAN) logic, Real-or-Random (ROR) model. A detailed comparative study existing competing schemes including demonstrates devised framework furnishes better while having lower computation costs comparable communication than schemes.
