Metaverse brings a new era of digital networking, blurring the lines between the physical and digital realms, enabling users to engage in social, educational, commercial and entertainment activities in a distributed environment. Especially in the field of education, this innovation brings various facilities and benefits, empowering all involved in a new world of learning. However, like the physical world, metaverse raises security and privacy issues that generate concerns among users, hampering its integration especially into everyday life, such as education. Therefore, in this work we identify security and privacy challenges associated with e-education metaverse environments, posing a series of research questions encompassing a wide spectrum of concerns. We also analyse protocols intended to create a trustworthy metaverse environment.
