The MP2PN contains some super peers and each super peer controls a subgroup composed of regular peers. An efficient attribute-based signature based on Cipertext-Policy Attribute-Based Encryption （CP-ABE） is proposed and used in this group-key rmnagement protocol to authenticate a peer＇s at- tributes and identity. A peer can be described by a set of attributes or one unique special identity at- tribute. Peers that have some attributes in common can form a group and conmmnicate with each other anonymously and securely. Any super peer can initiate a group and act as a group controller.
