The structure of mobile agent for web services is based on the combination of Intelligent Agent and Mobile Devices System to replace the Web Services requesters.

本研究以一個查詢書藉的網(wǎng)路服務(wù)的實作女生精黄色网站，驗證行動代理人網(wǎng)路服務(wù)架構(gòu)的實用性色色色色色色色色色播播，了解如何在行動平臺中使用網(wǎng)路服務(wù)技術(shù)，讓網(wǎng)路服務(wù)的架構(gòu)落實在行動平臺架構(gòu)中免费人成网站视频在线观看。

But the oldest pending request uncovered in a new survey of 87 agencies and departments has been awaiting a response for 20 years, and 16 requesters have been waiting more than 15 years for results.

但是對 87個機(jī)構(gòu)和部門的新調(diào)查揭示最久未決定的請求等候一個回應(yīng)已經(jīng)達(dá) 20 年之久全网免费在线观看一级片，而且 16個請求者等候結(jié)果已經(jīng)超過 15 年。

In order to provide service which could be used by more requesters without dead-locks under the service-oriented architecture, a method based on a message state tree was proposed to realize the reverse design of services by interactive message sequences.

在面向服務(wù)架構(gòu)下免费av黄色录像免费的黄色录像，為了讓更多的相關(guān)服務(wù)請求者使用用戶設(shè)計的服務(wù)而不發(fā)生死鎖视频一区二区男人的天堂国产大片免费，提出了一種基于消息狀態(tài)樹的方法，該方法由外部交互消息序列逆向設(shè)計無環(huán)有限次交互的服務(wù)自拍偷拍亚洲精品。

However, under cross-enterprise environment, Service Requesters not only have changeable demand, but also difficult to find, Service Provider must create services in the situation of don't know where are users at and what they need.

然而一级aa片视频，在跨企業(yè)大規(guī)模的使用環(huán)境下，服務(wù)使用者不但需求多變国产日韩欧美主播，且難以被發(fā)現(xiàn)亚洲欧美国产色图，服務(wù)提供者因此必須在不知使用者在哪以及有何需求的狀況下開發(fā)服務(wù)。

Nevertheless, the requesters are concerned about not only the availability of the resources, but also the potential risks that they are running in grid environments.

網(wǎng)格環(huán)境下訪問主體不僅僅關(guān)心獲取的資源是否可用99久久播放视频，還要考慮共享資源可能對自身造成破壞日韩三级中文字幕，需要對交互的雙方都提供保護(hù)機(jī)制。

So some key issues of access control and trust management in grid environments are researched in this thesis and our work mainly include: The traditional security mechanisms are mainly concerned about the security of the provider of resources and miss the protection of the access requesters.

為解決網(wǎng)格環(huán)境的動態(tài)性和不確定性帶來的安全問題99色免费看视频，對網(wǎng)格環(huán)境下的訪問控制和信任模型進(jìn)行深入研究国产精品久久久久精品三级一区，既具有理論意義亦具有實用價值，研究內(nèi)容主要包括：傳統(tǒng)的訪問控制方法僅僅對資源提供方提供了保護(hù)无码观看黄三级网站，沒有考慮訪問主體的安全www熟女。

Given the ability to negotiate, requesters can continuously customize their needs according to their preferences; providers can tailor their offers based on their actual resource usage situation; furthermore, multiple service providers can collaborate and coordinate in order to satisfy a request that they can't do alone.

在服務(wù)發(fā)現(xiàn)的過程完成以后，服務(wù)提供者和服務(wù)請求者通過服務(wù)協(xié)商免费观看黃色A片一级视频快进，對服務(wù)的各個方面免费一级无码婬片AA片高潮喷水，尤其是服務(wù)的非功能方面，達(dá)成一致的意見并形成一個正式的服務(wù)合約人人干操操操插，用這個合約來規(guī)范服務(wù)交付的過程免费在线看欧美三级片。

A critical step, to that end, is the service discovery. The current method to find web services in UDDI registry is based on the keyword and the category. These kinds of methods are not effective. For the moment, service requesters are hard to search the desired web services.

然而要達(dá)到上述理想中的愿景，有一個關(guān)鍵的步驟必須先被達(dá)成色视频网站观看，那就是網(wǎng)路服務(wù)的搜尋欧美国产日韩激情视频，軟體工程師必須要能找到他們理想中的服務(wù)方能達(dá)成此愿景，目前在UDDI上的搜尋方法是以關(guān)鍵字和服務(wù)分類為基礎(chǔ)的搜尋方法国产伦频网，這種方法并不能有效地幫助使用者找到他們所需要的服務(wù)看h片的网站，因此目前網(wǎng)路服務(wù)的搜尋仍是一個有待解決的議題。

On the other hand, a service provider may receive many requests at the same time, and because of the limited resources, it can't serve all of them. Consequently, for both service requesters and providers, there is a challenge of selecting interaction partners. This can be achieved by our proposed one-to-many service negotiation model.

As a special digital signature, blind signature can insure signing requesters anonymity. Thus it has a wide prospect in the electronic cash and electronic voting systems.
