【正文】 該系統(tǒng)是基于對安 全的Web 服務體系結構，可以提高餐館效率，節(jié)省時間，減少人為錯誤，并提供更高質量的客戶服務。訂貨管理的食品，是負責監(jiān)督食品從有線用戶和無線用戶訂購信息。上下文服務器連接到 Web 服務器作為 IIS 作為 Web 服務器。該系統(tǒng)使用 SOAP 工具包由微軟，它提供了支持基于 IIS 安全基礎設施，以實現(xiàn)應用程序級安全模型的互聯(lián)網(wǎng)安全 。一個常用的方法是通過在 SOAP 頭一票（或用戶名稱或許可證）。安全套接字層（ SSL）是用來提供消息完整性和保密性。網(wǎng)絡的消息時，在運輸通道運輸，整個數(shù)據(jù)流進行加密，確保運輸安全。此系統(tǒng)平臺和應用程序級安全性的重點，因此，描述了兩個安全級別。移動環(huán)境中的服務器重新配置 Web 服務器提供的內(nèi)容。在有線網(wǎng)絡上的一個桌面可以被用于瀏覽在一個屏幕上拍攝的全部內(nèi)容。數(shù)據(jù)庫服務器保存的食品信息，訂購信息，客戶信息，如系統(tǒng)的所有信息。 Web 服務器提供的有關信息為移動設備或臺式電腦，有線 /無線綜合局域網(wǎng)絡使用WSDL（ Web 服務描述語言）來描述功能和協(xié)議。 Web 服務成為 SOA 應用開發(fā)的最佳選擇。 Web 服務提供的功能可以很簡單，但它也包含了特別復雜的業(yè)務邏輯。因為他們預計將有越來越多的熟悉和接受多個用戶之間提供了極大的技術承諾， Web 服務是一個有趣的話題調查其可能的應用在許多系統(tǒng)。今天，無線局域網(wǎng)正在成為更廣泛地作為一個通 用連接替代了企業(yè)客戶的廣泛認可。在辦公室時，他們可能會訪問 WLAN 通過無線接入點。 無線局域網(wǎng)的 IEEE 標準組指定的技術。基于 Web 服務的移動設備上的無線應用提供了一個方便的手段，提高工作效率和準確性。訂購流程中的錯誤導致不正確或序列準備膳食或非消耗和增加成本的業(yè)務結果。一貫的經(jīng)營模式，通過整合這些技術，可以實現(xiàn)一系列廣泛的設備上：不只是在經(jīng)營移動網(wǎng)絡的移動設備，但也對服務器和個人電腦連接到互聯(lián)網(wǎng)。如 PDA 等移動設備所提供的便利和強大的功能，鼓勵了很多人來調查使用它們的好處。在這個系統(tǒng)中，實現(xiàn)了有線和無線數(shù)據(jù)訪問訂購通過臺式電腦和移動設備，如超過有線 /無線綜合局域網(wǎng)的掌上電腦功能的服務器和食品。 security I. I NTRODUCTION The rapid developments in information technology, particularly in wireless munication and web services technologies, are greatly changing the way people access and work with information. The convenience and powerful functionality offered by mobile devices such as PDAs, has encouraged many people to investigate the benefits of using them. Wireless and handheld devices abound as vendors pitch the mon themes of onetoone puting, instant munication and anytime, anywhere information access. While web services provide a technology for serviceoriented puting. Web services allow programs written in different languages on different platforms to municate with each other in a standard way . By integrating these technologies, consistent business models can be implemented on a broad array of devices: not just on mobile devices operating over mobile works, but also on servers and PCs connected to the Inter. The food ordering process in restaurants requires the coordination of simple tasks. Instruction flows mainly from customers to waiters then to kitchen and/or the bar staff, finally to the cashier . In a medium to large and busy restaurant this coordination is a challenge and requires an efficient ordering system. Errors in ordering processes lead to incorrect or out of sequence meal preparation or nonconsumable and results in added cost to the business. This paper presents an integration of wireless munication technologies and web services technologies to realize a wireless food ordering system. In this system, it implements wired and wireless data access to the servers and food ordering functions through both desktop PCs and mobile devices such as PDAs over a wired/wireless integrated local area work. The system is based on secure web service architecture and some security strategies to ensure mobile munication security are adopted. Web servicesbased wireless applications on mobile devices provide a means of convenience, improving efficiency and accuracy. II. W IRELESS LAN AND W EB SERVICES A. Wireless LAN A wireless LAN (WLAN, Wireless Local Area Network) is a flexible data munication system implemented as an extension to or as an alternative for, a wired LAN within a building or camp
