Role-based Authentication with Privacy
Proposed a new way of Role-based authentication.This approach,through the use of a credential which holds the role of user's,can not only meet the requirement of verification of user but protect the user's privacy of identity.In the approach,one random and unique,short-lived identifier is embedded into the credential,and this identifier can not be tracked or linked to disclose the user's identity,meanwhile by using it services can differentiate each user.Relevant analysis presents the approach is secure,easy to deploy,and also has a close tie with role-based authorization.
