A seamless authentication for intra and inter metaverse platforms using blockchain

Abstract

The metaverse is a concept that refers to a virtual reality space where people can interact with each other and their surroundings in a virtual world. It is a vital to prioritize security and adopt security measures in metaverse environment to protect users from potential risks and threats. By implementing strong mutual authentication and authorization controls, the metaverse can be a safer place where people can freely interact and engage without worrying about their security. In this paper, we aim to address the above challenges by integrating blockchain into the metaverse. Furthermore, the use of cryptography in blockchain ensures that each user’s identity and personal information remain safe and secure. Trust and confidence are ensured through a seamless mutual authentication algorithm between the server-avatar and the avatar–avatar in the intra and inter domains of the metaverse. Moreover, the proposed approach makes it possible to manage the personal information of avatars autonomously without resorting to a trusted authority. We prove that the proposed system can resist malicious security attacks and ensures privacy preservation by performing security analyses, using AVISPA tool and BAN logic. In addition, the results of computation cost, communication cost and round trip delay (RTD) prove that the performance of our proposal is better suited to the metaverse environment compared to competing systems.
