网格环境下的资源描述与安全访问
发布时间：2018-12-26 09:16
【摘要】： 网格资源具有以往分布是系统所不具备的特定,为更好地管理网格资源,实现资源的高效应用共享和安全访问,本文对网格资源描述问题和安全访问问题进行研究,主要包括以下方面的内容: 在网格资源描述方面,为了对用户作业和资源进行统一描述,以达到定义作业和资源的属性、限制、约束和首选项的目的,设计了公用描述语言CDL(Common Description Language),该描述语言基于广告分类语言ClassAd,采用用属性/值对的方式,定义了自己的语法、语义和句法等,并考虑到网格环境中的经济因素,定义了一些经济属性。同时在网格环境中应用该语言建立了相应的资源作业匹配框架,通过它可以实现提交作业、取消作业执行、查询匹配的资源列表等功能,实现了该语言的网格应用。 在网格资源安全访问方面,本文对IBE系统进行了改进并在此基础上提出了网格资源安全访问的模型。为解决了部署IBE系统所遇到的问题,扩大IBE系统的应用范围,使之更加适用于网格等领域,通过加入辅助认证方(TA)的方式实现信任转移,解决密钥托管的问题;通过引入身份别名,方便了私钥更新。在此基础上设计了基于身份别名与辅助认证方的IBE方案的网格资源安全访问模型,实现了资源的安全访问。另外,从基于经济模型的网格资源分配和任务调度的角度出发,将货物市场模型和拍卖模型进行比较。
[Abstract]:In order to manage grid resources better and realize efficient application sharing and secure access, this paper studies grid resource description problem and security access problem. It mainly includes the following aspects: in the aspect of grid resource description, in order to describe users' jobs and resources in a unified way, the purpose of defining properties, constraints, constraints and preferences of jobs and resources is achieved. This paper designs a common description language (CDL (Common Description Language), which is based on the advertising classification language ClassAd, defines its own syntax, semantics and syntax by using attribute / value pairs, and takes into account the economic factors in the grid environment. Some economic attributes are defined. At the same time, the corresponding resource job matching framework is established by using the language in grid environment. It can realize the functions of submitting jobs, canceling job execution, querying matching resource list and so on, and realizing the grid application of the language. In the aspect of secure access to grid resources, this paper improves the IBE system and puts forward a model of secure access to grid resources. In order to solve the problems encountered in the deployment of IBE system, expand the application scope of IBE system, make it more suitable for grid and other fields, the trust transfer can be realized by adding (TA), and the problem of key escrow can be solved. By introducing identity aliases, private key updates are facilitated. On this basis, the secure access model of grid resources based on IBE scheme of identity alias and auxiliary authenticator is designed, and the secure access of resources is realized. In addition, from the point of view of grid resource allocation and task scheduling based on economic model, the goods market model and auction model are compared.
