This study aimed to synthesize the literature on Metaverse to highlight its current research, opportunities, and applications in e-healthcare and education to reduce inequalities and for delivering fair and equal opportunities and solutions. The authors employed preferred reporting items for systematic reviews and meta-analyses (PRISMA) to rapidly map the field of a metaverse in health and education. Two major application domains emerged in the literature from the 88 research publications, which include (1) Metaverse in healthcare and (2) Metaverse in education. This study will act as a road map to help academics who desire to continue their research work in the Metaverse for various healthcare and educational services. However, its implementation is required in the future to improve mental healthcare and the effectiveness of mental health services, particularly in low and medium-income (LMIC) and conflict-affected areas.
The aim of this paper is to create a secret key between two different IoT wireless entities while not the necessity for sharing the key manually. The idea behind this is to generate the key based on the received signal strength (RSS) of the wireless signals. The RSS would be different for the two entities that are involved in communication based on their location and environment. Eavesdropper would not be able to detect these secret keys because the hacker would be located in a position other than the entities involved in the communication. This means that the RSS would be unique between any two entities and the signals and their strengths would not be the same for the hacker. Hence the secret bits abstracted out of the RSS which are falling outside the threshold levels will be definitely unique. This creates a novel plan & unique idea of creating the secret bits. The same calculation will be done on both the entities and eventually they will communicate with each other to come to a common shared key. Once the secret key is finalized, then the communication will begin with enhanced or increased security than before.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
