But then the integration of wearables with the metaverse has some serious security, privacy, and trust implications. In this dissertation, we propose a trust- based secure access control mechanism dedicated to wearable devices inside the metaverse. The proposed approach makes sure the trustworthiness of the network by examining four trust parameters, i.e., security, privacy, integrity, and availability. The trustworthiness measurement of the system is described, and a weighted trust score is computed to measure the reliability of the system, and a comprehensive authentication protocol is designed, combining multi-factor authentication principles, encryption, certain hashing mechanisms and a session key generation process. Using the AVISPA tool, the architecture is validated and discusses the resilience to the well known attacks impersonation, replay and theft. The results give a story to the efficacy of the lightweight framework to establish a secure environment for wearables in the metaverse. This research adds to the growing bank of knowledge in the field of improving the safety, security and reliability of virtual environments for end users.enDepartment of Computer ScienceSP23Computer ScienceDesignMetaverseWearable DevicesDr. Tariq UmerThesis
