  • receiving, by an enrollment server in a peer-to-peer network, an enrollment request of a peer device, wherein the enrollment request comprises identity information of the peer device;

    verifying, by the enrollment server, the identity information of the peer device, and when the verification succeeds, obtaining peer location information of the peer device, and generating a peer credential of the peer device according to the peer location information, wherein the peer credential includes anti-counterfeiting information which verifies the peer credential, wherein the anti-counterfeiting information comprises a character string for generating check information by applying an algorithm and the peer credential is verified by comparing the generated check information and preset check information; and

    sending, by the enrollment server, the peer credential comprising the peer location information to the peer device, wherein the peer credential is used by the peer device to join the peer-to-peer network, the peer-to-peer network configured to prevent malicious peers without peer credentials from joining, andwherein upon successfully joining the peer-to-peer network, a second peer device in the peer-to-peer network updates a routing table of the second peer device according to the peer credential of the peer device.
