【摘要】 为解决传统VPN(Virtual Private Network)可扩展性差、接入终端和接入方式单一化等问题,提出一种新型的P2P(Peer-to-Peer)-VPN组网模式。该模式将P2P技术引入VPN网络中,使P2P技术的搜索机制也能被VPN网络所利用,从而提高了VPN的灵活性和可扩展性,接入终端和接入方式多样化。同时通过第三方认证和交叉认证方式实现双方身份的有效性验证,克服了由于P2P的引入而引起VPN网络的安全性下降问题,进一步加强了P2P-VPN组网模式的安全性。更多还原

【Abstract】 In order to solve several problems of typical VPN(Virtual Private Network) network,including the deficiency of extension mechanism,deficiency of management,singleness of access terminal and access methods,a new network building mode called P2P(Peer-to-Peer)-VPN is discussed.The advanced search mechanism of P2P technology will be adopted to VPN network to improve the flexibility,expandability,access terminal and access method diversity of traditional VPN network.Meanwhile,the weak security of the network caused by P2P technology can be avoided by the effectiveness verification from the third-party certification and identity authentication.更多还原
