  • XML Web Service is a new distributed computing paradigm for combining all computer systems through the on-line standardized open network, so it is expected that companies can get the results of increasing profits and reducing costs through this. Especially XML Web Service is essential in mobile environment. In this paper, a new XML Web Service is proposed and it is based on WIPI-based XML standard technology and mobile web service standard. The proposed XML Web Service embodied XML Parser which can be used in WIPI environment and made HTTP communication. In addition, as an example of the practical application, it was applied to an inventory Management, Book Store using JAVA language for WIPI.

  • XML Web Service based on internet can cause problems on transmission speed and data error. Also system analysis results simulated by several different research groups can hardly have reliability because of error data that come from improperly managed files. In order to solve this problems, algorithm sever using XML Web Service is shared on the internet so widely that various application programs based on basic analysis module with a united IO can be developed. And also XML Dataset DB is interacted with XML Web Service, which prevents propagation of error data. It causes to improve reliabilityon the load flow analysis result and solve the problems on data error or transmission speed that can possibly come from internet.

  • XKMS(XML Key Management Specification), one of XML Security specification, defines the protocol for distributing and registering public keys for verifying digital signatures and enciphering XML documents of web service applications with various and complicate functions. In this paper, we propose XML Key Information protocol service model and implements reference model of protocol component based on standard specification. Also describes the analysis and security method of Key Information Service(XKIS) for Secure XML Web Service,paying attention to the features of XML based security service. This protocol component supported includes public key location by given identifier information, the binding of such keys to edentifier information. This reference model offers the security construction guideline for future domestric e-Business Frameworks.

  • With the spread of Internet, e-business using Internet technology is being actively developed and operated. Currently, on behalf of the international e-business framework, International standard such as ebXML and Web Service is being advanced. We are able to publish and search business information through ebXML and Web Service and then actual trading between partners is accomplished. By the way, it is Registry that play an important part in e-business. Registry is an e-business infrastructure for enabling building, deploying, and the discovery of business Information. We can do e-business through Registries dynamically and share the resources. Representatives of Registry are ebXML and UDDI used as an international standard. We will meet with some problems when using Registries. ebXML Is focused on B2B collaborations and Web Service Is focused on application integrations. So we must use ebXML and Web Service characteristically, and sometimes use all at need. ebXML and Web Service contain business information by Registry specific way. So When using the services offered by ebXML and Web Service, we should access each Registry by using Registry specific tools. This thesis intended to integrate business information from ebXML Registry and UDDI Registry to accomplish e-business conveniently This thesis defined the common data model as well as integrated query language for integrated access to ebXML and Web Service along with design and implementation of the system.

  • Web Services가 차세대 e-Business를 주도할 것으로 많은 주목을 받으면서 XML(extensible Markup Language)을 기반으로 하여 폭넓게 성장해 가고 있다. 하지만 안전한 서비스의 측면에서 Web Services 는 폐쇄환경에서는 존재하지 않았던 새로운 보안 고려사항들을 부각시키고 있다. 이에 대한 해결을 위해 본 논문에서는 XML을 기반으로 하는 Web Services의 특성에 맞추어, 플랫폼 독립적이며 언어 중립적인 특징을 유지한 XML-Signcryption을 제안하는데, 이것은 논리적으로 한번에 전자 서명과 암호화를 함께 수행하도록 하여 기존의 서명 후 암호화에서 요구되는 계산 비용보다 더 적은 비용을 가지고 있는 Zheng의 Signcryption 기법을 XML 보안에 응용한 것이다. 본 논문에서 처음으로 XML 구문 형식을 따라 XML-Signcryption이란 명칭으로 설계하여 제안하는 XML-Signcryption은 암호화와 전자서명을 따로 구현한 W3C(World Wide Web Consortium)의 XML-Encryption이나 XML-Signature 스펙과 비교해, 전자서명과 암호화의 두 가지 보안 메커니즘을 위한 각각의 구현을 따로 할 필요 없이 한번에 할 수 있다는 면에서 개발자들에게 편리성을 제공할 뿐만 아니라 계산 비용 측면에서도 효율적인 장점을 제공한다.

  • Information searched in UDDI transfer web service user. Then web service user require interface to web service publisher. In this paper, we abbreviate procedure it. UDDI require WSDL document to web service publisher. For this reason, UDDI transfer XML form message to publisher. Message include user's location information and UDDI required document transfer from publisher to user. Message using SOAP protocol of XML format.

  • For the excellent U web services, the program developers should create both user's client program and the sewer program Recently, the structural alteration of programs are often caused by infernal and external environment concerned with social trends and preferences as well as user's requirements expectations. So, for reducing the development time and workload of XML web service programs, it is necessary to develop the web program generation tools. This paper suggest how to design and implement the web-based XML Tree builder, which was able to provide the information for promptly and easily generating the XML Schema, XML Stylesheet and XML Document through the XML Development Supporting Server System.

  • Recently, business integration and interoperability of between the heterogeneous applications are requested by rapid growth of web. Web Services that self-contained for platform and programming language is appeared used to XML of standard data format. Such amid Fast Web Services attract attention at fields necessary to bring rapid communication like Mobile and RFID. In this paper, we inquired about ASN.1 of ITU-T and IS0/IEC standard that a central role of data transform. And we studied encoding process of between ASN.1 and XML for transform SOAP massage of a massage transfer mode of Web Services to binary data.

  • In this paper, we study the data interoperability problem of web services in terms of XML schema compatibility. When Web Service A sends XML messages to Web Service B, A is interoperable with B if B can accept all messages from A. That is, the XML schema R for B to receive XML instances must be compatible with the XML schema S for A to send XML instances, Le., A is a subschema of B. We propose a formal model called Schema Automaton (SA) to model W3C XML Schema (XSD) and develop several algorithms to perform different XML schema computations. The computations include schema minimization, schema equivalence testing, subschema testing, and subschema extraction. We have conducted experiments on an e-commerce standard XSD called xCBL to demonstrate the practicality of our algorithms. One experiment has refuted the claim that the xCBL 3.5 XSD is backward compatible with the xCBL 3.0 XSD. Another experiment has shown that the xCBL XSDs can be effectively trimmed into small subschemas for specific applications, which has significantly reduced the schema processing time.
