Abstract


P2P technology in the rapid development and popularization of the network has become a major way for the exchange of information . It is a new network architecture based on distributed computing model , the main goal of its design is direct communication between individuals to exchange information resources, without relying on a central server role as a bridge . P2P technology has been widely applied mainly because low-cost solution to the network in a distributed environment , scalability , autonomy , and load balancing have greater advantages . Mutual recognition between traditional network terminal authentication scheme can not be directly applied to their own existence decentralized P2P network model , the authenticity of the information can not be guaranteed . P2P network the autonomy feature allows any node joining and leaving , it is likely to affect the security of the network . Therefore , taken the safe and efficient measures to reduce the harm of malicious nodes on the system , and how to build a safe and P2P network environment is still hot and difficult research at this stage . In recent years , the trusted computing technology by the attention of scholars at home and abroad , especially in its remote attestation mechanism put forward new ideas for the protection of the security of the terminal host . The introduction of anonymous identity proof and integrity that can better address the user node in the P2P network privacy leak their unreliable platform runtime environment security issues . The paper presents a remote automatic proof of trust negotiation mechanism based on trusted computing technologies and ring signature technology . And its use in the P2P network model , in order to improve the efficiency of the mutual authentication between the security and privacy of information exchange and network entities . Trusted Platform Module and ring signature technology trusted computing hardware level added to the users of the P2P network node , on the one hand to ensure that the information from the real not fake user entities , entity integrity authentication protection . On the other hand the sharing of information between entities can not be any tampering, so you can construct a safe , efficient , harmonious network environment .
