摘　　要：针对现有信任模型不能很好地解决信任信息有效共享问题。从模拟人类社会信任建立过程出发,提出了开放网络中基于群组的信任模型,并给出了信任初始化算法以及对自私节点和不诚实节点的惩罚机制。最后,通过仿真实验验证模型能够有效地收集推荐信息,同时减少恶意推荐对信任合成的影响。The existing trust models can not solve the problem of sharing trust information effectively. In this paper it proposes a trust model based on community in open network against the above problem ,which comes from the simulation of trust establishing process in mankind social network ,and an initialized trust value algorithm and the punishing mechanism for selfish peers and dishonest peers are given as well. The emulation experiment results show the trust model collects recommended trust information effectively, and reduces the influence which malicious recommendation brings to trust combination.
