【摘要】： 網(wǎng)格資源具有以往分布是系統(tǒng)所不具備的特定,為更好地管理網(wǎng)格資源,實(shí)現(xiàn)資源的高效應(yīng)用共享和安全訪問,本文對(duì)網(wǎng)格資源描述問題和安全訪問問題進(jìn)行研究,主要包括以下方面的內(nèi)容: 在網(wǎng)格資源描述方面,為了對(duì)用戶作業(yè)和資源進(jìn)行統(tǒng)一描述,以達(dá)到定義作業(yè)和資源的屬性、限制、約束和首選項(xiàng)的目的,設(shè)計(jì)了公用描述語(yǔ)言CDL(Common Description Language),該描述語(yǔ)言基于廣告分類語(yǔ)言ClassAd,采用用屬性/值對(duì)的方式,定義了自己的語(yǔ)法、語(yǔ)義和句法等,并考慮到網(wǎng)格環(huán)境中的經(jīng)濟(jì)因素,定義了一些經(jīng)濟(jì)屬性。同時(shí)在網(wǎng)格環(huán)境中應(yīng)用該語(yǔ)言建立了相應(yīng)的資源作業(yè)匹配框架,通過它可以實(shí)現(xiàn)提交作業(yè)、取消作業(yè)執(zhí)行、查詢匹配的資源列表等功能,實(shí)現(xiàn)了該語(yǔ)言的網(wǎng)格應(yīng)用。 在網(wǎng)格資源安全訪問方面,本文對(duì)IBE系統(tǒng)進(jìn)行了改進(jìn)并在此基礎(chǔ)上提出了網(wǎng)格資源安全訪問的模型。為解決了部署IBE系統(tǒng)所遇到的問題,擴(kuò)大IBE系統(tǒng)的應(yīng)用范圍,使之更加適用于網(wǎng)格等領(lǐng)域,通過加入輔助認(rèn)證方(TA)的方式實(shí)現(xiàn)信任轉(zhuǎn)移,解決密鑰托管的問題;通過引入身份別名,方便了私鑰更新。在此基礎(chǔ)上設(shè)計(jì)了基于身份別名與輔助認(rèn)證方的IBE方案的網(wǎng)格資源安全訪問模型,實(shí)現(xiàn)了資源的安全訪問。另外,從基于經(jīng)濟(jì)模型的網(wǎng)格資源分配和任務(wù)調(diào)度的角度出發(fā),將貨物市場(chǎng)模型和拍賣模型進(jìn)行比較。
[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.
