摘要：P2P网络通信安全是制约其发展的重要因素，现有的模型虽然能保证通信节点间数据的真实性、保密性和完整性，但是却会带来很大的开销或系统的不稳定。针对上述问题，提出了一种基于自适应认证的P2P安全通信模型，采用Certification Authority(CA)认证和CA监管机制，保障了系统的稳定性，并且只需要较小的开销，即可为P2P安全通信模型提供了一种新的思路。本模型可方便地加入到现有的P2P网络中。安全分析和仿真实验结果进一步表明，本模型具有有效性和可行性。

Abstract: The secure of P2P networks communication is the main problem which restricts the development of P2P networks. Current models can guarantee the authenticity, confidentiality and integrity of datas in P2P networks communication; however, they bring great overhead or instability. Aiming at solving these problems, a novel P2P security communication model based on adaptiveauthenticity was presented, CA(Certification Authority) and CA supervise mechanism were used, the stability of P2P and less overhead were guaranteed, and a new thought in P2P security communication model was provided. The model can be joined into existing P2P networks easily. The test results indicate that the proposed model is efficient and feasible.
