Access authentication method, equipment and system of P2P (peer-to-peer) network

Abstract

The invention discloses access authentication method, equipment and system of a P2P (peer-to-peer) network, belonging to the technical field of network communication. Network equipment in the P2P network is subjected to access authentication by adopting an identity-based public key IBC (Information Bearer Channel) mechanism. The method comprises the following steps of: receiving an access requesttransmitted by opposite terminal network equipment by home terminal network equipment; selecting a private key from the private keys of the home terminal network equipment as a conversation private key of the home terminal network equipment according to the private key level of the home terminal network equipment and the private key level of the opposite terminal network equipment; calculating a conversation main key of the home terminal network equipment according to the conversation private key of the home terminal network equipment, the identity information of the opposite terminal networkequipment corresponding to the conversation private key of the home terminal network equipment, a first negotiation parameter and a second random number determined by the home terminal network equipment; and returning an access response to the opposite terminal network equipment. By utilizing the IBC mechanism, distributed access authentication under the P2P network mode is solved, thus the IBC mechanism is particularly suitable for the P2P network.

Description

technical field The present invention relates to the field of communication technology, in particular to a P2P (Peer to Peer, peer-to-peer) network access authentication method, equipment and system. Background technique P2P network is a network that directly connects people and allows people to interact directly through the Internet. The P2P network gets rid of the traditional C (Client, client) / S (Server, server) mode of service, so that each user in the network can exchange data and make full use of the resources at the edge of the network. A typical P2P network is a wireless Mesh (mesh) network. The wireless Mesh network is composed of a group of MPs (Mesh Points, mesh network nodes) distributed in a mesh shape, and each MP is interconnected through a wireless relay link in a P2P manner. The multi-hop connection of the wireless Mesh network will become the development trend of the next-generation wireless communication network, which can provide users with truly ubiqui...
