元宇宙环境下的身份认证综述OA北大核心CSTPCD

The identity authentication schemes in the traditional network environment are designed according to the char-acteristics of their own environments,which are difficult to meet the design requirements in the metaverse environment.In order to solve the problem of identity authentication in the metaverse environment,the characteristics,attributes,appli-cation scenarios and main attack threats faced by the metaverse are studied.The identity privacy and security risks related to users,avatars,platforms,wearable devices and communications in the metaverse are discussed.The work related to identity authentication in the metaverse environment is sorted out and categorized into user-avatar,user-platform and user-wearable device authentication.Finally,the research directions of identity authentication mechanism in the metaverse environment are discussed.
