Embodiment 1

[0034] In order to make the access authentication of the P2P network easier and simpler, the embodiment of the present invention provides an access authentication method of the P2P network. The network equipment in the P2P network adopts the IBC mechanism for access authentication. See figure 1 , the method includes:

[0035] 101: The local network device receives the access request sent by the peer network device. The access request carries the identity information of the peer network device and the first negotiation parameter. The identity information includes the identity of the peer network device and the private key of the peer network device. key level;

[0036] 102: According to the private key level of the local network device and the private key level of the peer network device, select one of the private keys of the local network device as the session private key of the local network device;

[0037] 103: Calculate the local network address based on the session priva...

Embodiment 2

[0041] In order to make the access authentication of the P2P network easier and simpler, the embodiment of the present invention provides an access authentication method of the P2P network, and the network equipment in the P2P network adopts the IBC mechanism to perform the access authentication.

[0042] Take Mesh as an example of a typical P2P network, see figure 2 , the preparations for the access authentication method of the P2P network include:

[0043] 201: Establish an IBC system.

Embodiment 3

[0150] In order to make the access authentication of the P2P network easier and simpler, the embodiment of the present invention provides an access authentication method of the P2P network, and the network equipment in the P2P network adopts the IBC mechanism to perform the access authentication. For the convenience of discussion, it is assumed that the local network device MPb has a private key Pri_Keyb, whose private key level is SN1, and the peer network device MPa has two private keys Pri_Keya0 and Pri_Keya1, whose private key levels are SN0 and SN1 respectively. The access authentication methods include, refer to Figure 4a , Figure 4b :

[0151] 401: Node MPb receives an access request sent by node MPa, where the access request includes: the identity of MPa, all private key levels, and first negotiation parameters corresponding to the private key levels.

[0152] The first negotiation parameter can be: (a×Pub_Keya), wherein, the first random number a is a random numbe...

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 [0001] 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 [0002] 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 w...
