This paper proposes a two-phase server login authentication system by XML-Signature schema extension to protect server's information resources opened on network which offer various web contents. A proposed system requests and publishes XML-based certificate through on-line, registers certificate extension information provided by CA(Certification Authority) to XCMS(XML Certificate Management Server), and performs prior authentication using user's certificate password. Then, it requests certificate extension information added by user besides user's certificate password and certificate extension information registered in XCMS by using SOAP message, and performs posterior authentication by comparing these certificate extension information. As a result, a proposed system is a security reinforced system compared with existing systems.

국내 주요 항만으로 반입되는 모든 운송사의 수출입 컨테이너는 반드시 항만을 관리하는 터미널 운영사에 해당 컨테이너의 주요 정보를 사전에 통지해야 하며 이를 컨테이너 운송 예정 정보라 부른다. 이는 항만 터미널 운영사가 반입 거점의 컨테이너의 야드 운영과 양적하 작업 계획을 사전에 계획하기 위함이다. 현재 국내 항만 터미널 운영사로 전송되는 컨테이너 반입 예정 정보는 특정 VAN 사업자를 통하여 EDI 로 정보를 송수신한다. 따라서 국내외 운송사들이 수출입 컨테이너를 항만에 반입하기 위해서는 별도의 비용을 지불하고 VAN 사업자의 EDI 서비스를 이용해야 한다. 또한 VAN 사업자의 EDI 시스템에 장애가 발생 할 경우 컨테이너 운송 예정 정보를 전송할 다른 방법은 현재 없는 상황이다. 이에 본 논문에서는 웹 서비스 기반의 SOAP 메시지 전송을 통하여 컨테이너 운송 예정 정보를 송수신 하는 시스템을 시범적으로 구축하고 이를 소개한다. 이를 통해 운송사와 항만 터미널 운영사는 VAN 사의 EDI 시스템 이외에 컨테이너 운송 예정 정보를 송수신하는 예비 전송망을 구축 할 수 있으며 EDI 사용 비용을 줄일 수가 있다.

In this paper, we design ZigBee RF based framework for mobile web service on collected data by sensor node and transmitting data to data base by sensor network and remote sensing server through wireless connection. The proposed system is an integrated platform of sensor network for the sensor management and providing SOA based sensor web access. This paper combines SOA technology with sensor network. composes sensor node as web view, and provides high capability. extensiveness, reliability, and usability to the user who accesses to sensor web. The mobile message conversion module, SOAP message processing module. WSDL message generator, and mobile web service module is embodied for improving the capacity of the framework. The capacity evaluation of local wireless communication system which is proposed in this paper is analyzed through NS-2 simulation.

his paper describes the framework of integrating the business processes of different organizations through the interoperability of workflow management systems. In particular, this framework can be applied to developing B2B systems, in which each trade partner has its own heterogeneous workflow system on the Internet. We propose an approach to implementing an interoperable workflow system which can be integrated with other heterogeneous workflow systems through the four scenarios suggested by WfMC(Workflow Management Coalition), and we developed XML message-based prototype systems, which using SOAP(Simple Object Access Protocol), is applicable to standard e-business framework such as ebXML.

Recently, as electronic commerce service via the Internet has expanded over the world, the standardization for the e-commerce has been strongly required. Therefore UN/CEFACT and OASIS adopted ebXML standard for the purpose of creating single global electronic marketplace. New e-Business systems should require ebXMl- based messaging system for reliable messaging delivery. In this paper, we have implemented Message Service Handler(MSH) packaging, transporting and managing e-Business messages for supporting ebXML messaging service. The MSH supports various system environments and allows high-level applications running either local or remote hosts with Remote Method Invocation(RMI) interface. In addition, MSH guarantees reliable message delivery on internet since it retransmits message in case of delivery failure and handles duplicated message and applies acknowledgement message for secure message delivery. Nowadays MSH has applied to ebXML registry/repository.

With the recent development of the ubiquitous computing technology, there are increasing interest and research in technologies such as sensors and RFID related to information recognition and location positioning in various ubiquitous fields. Especially, a standard specification was required for compatibility and interoperability in various RTLS(Real-Time Locating Systems) according to the development of RTLS to provide location and status information of moving objects using the RFID Tag. For these reasons, the ISO/IEC published the RTLS standard specification for compatibility and interoperability in RTLS. Therefore, in this paper, we designed and im plemented RTLS based on the spatial DSMS(Data Stream Management Stream) for efficiently managing and searching the incoming data stream of moving objects. The spatial DSMS is an extended system of STREAM(STanford stREam datA Manager) developed by Standford University to make various spatial operations possible. RTLS based on the spatial DSMS uses the SOAP(Simple Object Access Protocol) message between client and server for interoperability and translates client's SOAP message into CQL(Continuous Query Language) of the spatial DSMS. Finally, we proved the efficiency of RTLS based on the spatial DSMS by applying it for the staff location management service.

This paper presents an architecture of UPnP Bridge that allows controlling Non-iP devices from UPnP control point, without modification to Non-IP device or UPnP control point implementations. UPnP devices must provide SSDP discovery, SOAP control and GENA event processes. To represent Non-IP devices to UPnP devices, UPnP Bridge provides these functionalities on behalf of Non-IP devices. We provides two method to interoperability between UPnP and Non-IP devices, Message Field Description, Non-UPnP Proxy devices. And solution to integrate heterogeneous networking standards(RS232C, CAN, IEEE1394, USB) is provided.

In order to manage the correct posture in daily life, it is necessary to evaluate the objective posture and appropriate prescription and management. The posture evaluation program is widely used as a method to evaluate posture relatively easily and safely. However, the existing posture evaluation program is evaluated by utilizing the position of the skeletal system, but lacks feedback on the result of the evaluation because the muscle information causing the posture is lacking and the efficiency of the program is decreased. Therefore, we will improve the existing posture evaluation program and design the system that helps the correct posture management by the appropriate exercise prescription based on the feedback that the server measures and stores the evaluation result through the SOAP message.

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.
