XML安全技术在水泥网格中的应用

网格计算是基于网格结构的问题求解模式,它将网络上分布的计算机资源组织起来协同解决复杂的科学与工程计算问题。我们基于Globus项目的研究成果及其工具包,开发了面向水泥材料设计与仿真的网格系统。本文结合XML安全技术及水泥网格自身的特点。研究了网格结点间的信任体系和安全策略。提出了一种用将XML签名及XML加密技术应用于网格计算的方法。     

TL:采集具有准确应用用信息的Internet流量样本（英文）

Traffic classification research has been suffering from a trouble of collecting accurate samples with ground truth.A model named Traffic Labeller(TL) is proposed to solve this problem.TL system captures all user socket calls and their corresponding application process information in the user mode on a Windows host.Once a sending data call has been captured,its 5-tuple {source IP,destination IP,source port,destination port and transport layer protocol},associated with its application information,is sent to an intermediate NDIS driver in the kernel mode.Then the intermediate driver writes application type information on TOS field of the IP packets which match the 5-tuple.In this way,each IP packet sent from the Windows host carries their application information.Therefore,traffic samples collected on the network have been labelled with the accurate application information and can be used for training effective traffic classification models.
