一种改进的社会网络动态信任模型
An Improved Dynamic Trust Model in Social Network
摘要
Abstract
In social network,the problem of large number of malicious services and the trust value unlikelihood or unreliable with the ma-licious nodes and the dynamic nodes which provide low quality service and network attack in trust calculating is researched. By analyzing the trust evaluation behavior of the node and the recommendation from the conspiracy node,an improved method to calculate and form trust value is proposed. Through introducing the subjective and objective evaluation of the node,combined with the GTFT and TFT,a re-lated punishment strategy is given for dishonest trust recommendation in recommending process. The simulation shows that the direct trust and recommendation trust based on the subjective evaluation and objective evaluation can promote the rational participation of the nodes, improving the unlikelihood or unreliable problem in trust calculation,and decrease the attack node in the network.关键词
