  • a communications interface adapted to facilitate communication on a peer-to-peer overlay network;

    a storage medium including a private key and public key pair associated with the group administrator peer node; and

    a processing circuit coupled to the communications interface and the storage medium, the processing circuit adapted to;

    create a peer group, the group defining one or more peer nodes as members of the group;

    assign a peer-specific certificate to a group member peer node that is a member of the group, the peer-specific certificate adapted to authenticate membership in the group to other peer nodes in the peer-to-peer overlay network and including a group identity, an identity of the group member peer node, a public key associated with the group member peer node, an identity of an issuing apparatus and a signature by a private key of the issuing apparatus over one or more components of the peer-specific certificate; and
