A P2P security communication model based on adaptive-authenticity

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.
