摘　　要：基于声誉的信任模型中,节点如何获取所需要的声誉信息是个关键问题。提出了一种基于蚂蚁的声誉信息分发算法。该算法通过模拟蚁群觅食的行为,实现了声誉信息在无集中式控制的P2P环境下的分发,解决了节点为建立信任关系获取声誉信息问题。仿真实验表明,该算法能使节点选择最佳路径获取声誉信息,降低了系统的负载,保证了节点获取声誉信息的可靠性和安全性。In the reputation-based trust model,how to obtain reputation is a key problem.This paper proposes an algorithm for ant-based reputation distribution.This algorithm realizes reputation distribution in P2P network by modeling the ants＇ behavior of looking for food.The new approach can obtain reputation for building trust relationships in P2P network.Theoretical analysis and simulations prove that it can effectively improve the reliability and security and decrease network load.
