This article proposed the authentication protocol for peer-to-peer resource sharing community. The proposed protocol does not require a priori information for generating and exchanging authentication key. Also this protocol can provide the delicate access control by allowing the user(authenticator) to assign the trust level to the authentication supplicant, which can be used to decide if the resource providing node will accept the resource sharing request from a resource requesting node. Trust Relationship Chaining provides the environment where trust levels (included in the trust table) of nodes in the resource sharing community are propagated among nodes when trust tables are exchanged between two nodes engaged in mutual authentication process and authentication refresh so that any two nodes which are not directly mutual-authenticated can assign the trust level each other for the access control for resource sharing. In the proposed protocol a node can implements the authentication refresh continuously to verify the effectiveness of authentication after mutual authentication so that the authentication of new node or authentication revocation(effectiveness cancellation) of the departed node can be propagated to the all the nodes in RSC and eventually safe resource sharing community is configured.
