Role-based access control model (RBAC) is a model widely used in the field of access control, but in the traditional civil peer-to-peer system, all users is unfamiliar with each other and is the interaction between users is a fully distributed " stranger visit strangers".
Therefore, most civil peer-to-peer system has no access control or adopts the access control mode based on reputation and prestige.
