XML DTD is defining expression of simple form for XML document, there is much difficulties to define structure of XML document. Solving XML DTD's problem, W3C was select XML schema by standard in 2001. This paper proposes a design to XML DBMS using Relational Database based on XML schema to be selected by standard from W3C to overcome XML DBMS's shortcoming using XML DTD.

Well documented, simplified and clarified source code is required for the mission critical application software area in which C programing language is generally used. We suggest an XML_based comment management system for C source code. The comment management system is composed of 6 modules including comment user module, reviewer module, comment extraction module, comment traceability link module, comment tag definition module and storage management module. The XML comment tags defined in this paper cover categories of the development process activities applying the IEEE standard 1028 and IEEE standard 1012. The XML Schema Is used to insert comments into C source code and to extract XML tags from C source code and the XSL-FO is used fur the visual display professing o( comment extraction results.

Traditionally, a L/C (letter of credit) has been known as a relatively low risk method of payment. This is why L/C has been used in international trade. However, L/C has a number of weak points such as high cost, long processing time, and complicated documents. Using an electronic L/C is one way to solve those weak points. In Korea, there are two types of electronic L/C. One is the EDI (Electronic Data Interchange) based L/C and the other one is the XML (Extensible Markup Language) based L/C. The former, established in 1990's, is sent from banks to the beneficiary solely through VAN (Value Added Network, KTNET) operators. On the other hand the latter, started in 2005, is sent from banks to KFTC (Korea Financial Telecommunications & Clearings Institute) for management of the L/C balance, as well as to KTNET. So far, paper L/C and EDI based L/C have been used overwhelmingly instead of XML based L/C in spite of the aforesaid disadvantages. In this paper, the authors examined empirically why the users of electronic L/C were reluctant to use XML based L/C. The results are as follows. First, the users of paper L/C were more dissatisfied than the users of electronic L/C due to many factors such as cost, the time required, and information reuse. Second, the users who have more experience with XML based L/C wanted to adopt integrated management with EDI based L/C more than the users who had not experienced XML based L/C. Third, the users who had used more than one form of L/C wanted to adopt integrated management to EDI and XML based L/C more than the users who had only used one form of L/C. Therefore, the authority for electronic L/C should consider a change of the policy from the XML based electronic L/C oriented to integrated management of the various types of L/C.

These days, XML is accepted and used to e commerce market broadly. But by reason of XML document can exist same form logically but several other forms physically, several problems can happen in application that judge effectiveness as physical form such as XML digital signature. Therefore, it is recommending to propose and use canonical XML algorithm to change identical XML document physically equally logically in W3C to solve this problems. We implemented system that nm Canonical XML algorithm that suggested in W3C that can change to mon elaborate regular document. Thus, interoperable with other application that takes W3C recommendation Also, as well as use in digital signature system for web service is useful, use in several system that physical identify is required when it exchanges na document for web service interoperability are considered to be valuable. Moreover, Adding the transformation ability between universal encoding scheme and EUC­KR that is internal encoding scheme should be Canonical XML Algorithm that is suited to internal circumstances, and this should be a foundation technique of international interoperability confirmedness.

Along with the developing of mobile communication technology, plenty of data transmission turn into possible in mobile environment. As the foundation, it can provide diverse mobile service. Especially the service which use electronic signature, and as the transmission of XML technology among the terminal digital signature information. By now, allowed plenty of validity confirmation questions that the digital signatures about the characteristic induced application of physical property XML. For this question, it can be solved through XML by Canonical XML 1.0 standards provided in W3C. But, because the question in the XML namespace attribute inheritance, proposed the restrictive solution. In order to solve this problem, proposes candidate plan of Canonical XML 1.1 standardized in W3C, and also even more standardization. In this paper, in order to support the widespread XML standardization in the moving environment. Standardizes Canonical XML 1.1 standard as the underlies, safeguarding the theoretical mutual identity of the XML documents, and constructing and realizing the XML standardization system.

These days, XML is accepted and used to e-commerce market broadly. But by reason of XML document has autonomy of expression that can exist same form logically but several other forms physically, several problems ran happen in application that judge effectiveness as physical form such as XML digital signature. Therefore, it is recommending to propose and use Canonical XML algorithm to change identical XML document physically equally logically in W3C to solve this problems. We implemented system that run Canonical XML algorithm that suggested in W3C that can change to more elaborate regular document. Thus, interpretable with other application that takes W3C recommendation. Also, as well as use in digital signature system for web service is useful, use in several system that physical identify is required when it exchanges XML document for web service interoperability are considered to be valuable. Moreover, Adding the transformation ability between universal encoding scheme and EUC-KR that is internal encoding scheme should be Canonical XML Algorithm that is suited to internal circumstances, and this should be a foundation technique of international interoperability confirmedness.

XML encryption is to provide confidentiality service, though not limited to, for web contents. XML encryption can be applied to entire data files as opaque objects, or more frequently to various parts of XML documents, supporting various encryption granularity. It is this characteristic that makes XML encryption a more efficient alternative for data confidentiality in various web applications than is possible with SSL/TLS, IPsec, PGP, or S/MIME. It is essential for successful deployment of XML encryption to achieve interoperability among the products implementing this technology, which requires the products to implement the XML encryption standards correctly. Conformance testing is to test if products implement the relevant standard correctly. In this paper we present a conformance testing method for XML encryption products and implement it. We will first look at XML encryption standards developed by W3C, and extract test criteria. Then we propose a testing method in which the encryption capability and the decryption capability of a product are tested separately. The proposed methody is actually implemented as a GUI-based testing tool and some test results are presented.

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.

As the XML is approved standard language by the UN, the progress which complemented the XML security has being processed rapidly. In this paper, we design and implement the "XML-Signcryption" as a security mechanism to protect the XML document that can operate between other platforms. The signature and encryption which is the standard specification in W3C needs to be able to proceed them separately. Generally the signature and encryption require four times modular exponential operation, however the signcryption only needed three times modular exponential operation. This will benefit overall system effectiveness in terms of cost. And this scheme offers to convenient the user, because the signature and encryption implement as a single XML format. This tool can save the parsing time as a number of tags is few within a document. And also, in this paper, based on a research of Web Services security, we can apply XML-Signcryption to the SOAP message to provide the security services. Based on the XML-Signcryption scheme which provides confidentiality, integrity, authentication and non-repudiation to the XML document and Web Service security simultaneously.
