Topological Potential Based Recommendation Trust Model for P2P Communities System

  • 摘要: 對等網(wǎng)(P2P)系統(tǒng)因其開放性和匿名性等特點易受到惡意攻擊和非法濫用，建立基于社區(qū)的信任模型是一個行之有效的解決途徑。而現(xiàn)有的模型忽略了節(jié)點的動態(tài)性、活躍度及影響范圍。該文在分析了P2P用戶模型后，提出一種基于拓撲勢的P2P社區(qū)推薦信任模型，綜合評估了節(jié)點的影響力、交易量及信任度。在該模型中，分別建立了社區(qū)內(nèi)部和跨社區(qū)信任度計算機制，給出了超級節(jié)點評選算法。最后的仿真實驗結(jié)果驗證了該信任模型的有效性和魯棒性。
    Abstract: The features of autonomy, anonymity and distribution make the P2P system vulnerable to malicious attack and abuse. A feasible resolution in such an open environment is to exploit a community-based trust model to build trust relationship between peers. However, the existing model ignores the dynamic feature, the scope of activity and the influence of peers. After analyzing the P2P user model, a topological potential based recommendation trust model is proposed to integrate the influences, transactions, and reputations of nodes. In this model, the trust metrics are divided into intra- and inter-community computing mechanism. Moreover, the algorithm of selecting super node is presented. Simulation results show that the proposed trust model is effective and robust.
