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.
本发明公开了一种P2P网络的接入认证方法、设备和系统,属于网络通讯技术领域。所述P2P网络中的网络设备采用基于身份公钥机制IBC进行接入认证,方法包括:本端网络设备接收对端网络设备发送的接入请求;根据所述本端网络设备的私钥级别和所述对端网络设备的私钥级别,从所述本端网络设备的私钥中选择一个作为所述本端网络设备的会话私钥;根据所述本端网络设备的会话私钥、所述本端网络设备的会话私钥对应的所述对端网络设备的身份信息、第一协商参数和所述本端网络设备确定的第二随机数,计算所述本端网络设备的会话主密钥;向所述对端网络设备返回接入响应。通过利用IBC机制,解决了P2P网络模式下分布式接入认证,非常适合P2P网络。
