基于对等网络的信任模型

Studies on Trust Models of P2P Network Security

在Client/Server网络架构得到普遍应用的格局中 ,对等网络却异军突起迅速发展。针对这种新兴架构提出了与传统架构不同的一种安全信任模型。它依据网络的推荐值建立节点间的信任关系 ,更好地保证网络的安全性和避免恶意攻击。给出了求解信任值的数学模型和具体算法 。

The peer-to-peer network structure is developed rapidly in a situation of popularity of Client/Server structure.A new trust model, which is quite different from those of traditional Client/Server structure is proposed.It can create the trust relationship upon 'recommendation' values between network nodes and therefore supply with a higher security and avoid vicious attacks. The mathematical models to resolve trust values and its algorithm are also given.Besides,the theoretical evaluation on this trust model is carried out.
