摘要
针对Hadoop架构云平台不能验证"合法"用户的行为是否可靠的问题,文章提出了基于Bayes均值信任模型和动态行为信任链,用于计算每个客户端的信任值,使得信任值满足阈值的用户获得相应服务资源。该方案能够防止合法客户端受到"被动"的拒绝服务攻击,提高了客户端获取服务资源的公平性,同时有效防止恶意节点的协同欺骗。
According to the problem of the cloud platform for Hadoop architecture not verifying the reliability of the behavior of its ＂legitimate＂ user, this paper proposes the Based on Bayes mean trust model and the trust link of dynamic behavior to compute the trust value of each client. The client with satisfying the threshold value will gain the corresponding the service resources.The scheme prevents the legitimate clients from being ＂passive＂ denial-of-service attacks and improves the fairness of the client access to service resources. It is also effective to prevent the cooperative deception of malicious nodes.
