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.

The movie — Matrix (1999) boosted our imagination about how further we can be immersed within the cyber world, i.e., world indistinguishable from real world. Nobody, including creators, had expected that aspirational fictional virtual worlds such as “ActiveWorlds (1995)” and “Second Life (2003)” would impact way of experiencing urban environments with many experiences embedded into a rich featured 3D environment. Are going to stay ourselves while existing in mirror world? fabricated, created imaginary becoming part or vice versa? recent once-in-a-lifetime pandemic has confirmed importance location time-independent Digital Twins (DTs) (i.e., scale models) cities their automated services which provide everybody equity accessibility.

Metaverse is a vast virtual environment parallel to the physical world in which users enjoy variety of services acting as an avatar. To build secure living habitat, it's vital ensure virtual-physical traceability that tracking malicious player via his avatars space. In this paper, we propose two-factor authentication framework based on biometric-based and chameleon signature. First, aiming at disguise space, design avatar's identity model verifiability identity. Second, facing efficiency keys holding cost, collision signature algorithm efficiently associated with its Finally, impersonation world, two decentralized protocols achieve real-time Security analysis indicates proposed guarantees consistency Simulation experiments show not only completes between but also achieves tracking.

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.
