유비쿼터스 환경에서 스마트 객체에 부착되는 RFID 태그에는 스마트 객체를 유일하게 식별하기 위한 식별자 만이 저장되고 객체의 상세 정보는 별도의 정보 서버에 분산 저장 및 관리가 된다. 이와 같이 분산되어 있는 정보를 사용하기 위해서는 사용자가 일일이 정보 서버의 위치를 알아 내고, 각 정보 서버로부터 필요한 정보를 얻어 와야 하는 문제가 발생한다. 본 논문에서는 여러 정보 서버에 분산 저장되어 있는 다양한 종류의 객체 정보를 실시간으로 통합하여 사용자에게 제공하고, 또한 객체 정보의 유형 및 특성에 따라 카탈로그 검색, 소유권 변화, 포함 관계 변화, 추적 등의 스마트 객체에 특화된 질의 기능을 제공하기 위한 스마트 객체 정보 통합을 위한 미들웨어의 설계 내용을 소개한다.

In smart home environment, certificate based signature technology is being studied by communication with Internet of Things(IoT) device. However, block - chain technology has attracted much attention because of the problems such as single - point error and management overhead of the trust server. Among them, Keyless Signature Infrastructure(KSI) provides integrity by configuring user authentication and global timestamp of distributed server into block chain by using hash-based one-time key. In this paper, we provide confidentiality by applying group key and key management based on multi - solution chain. In addition, we propose a smart home environment that can reduce the storage space by using Extended Merkle Tree and secure and efficient KSI-based authentication and communication with enhanced security strength.

It becomes common to use computers to control electronic devices and security facilities in newly constructed buildings and house. There are many home application devices in the market which can be controlled by computers. But they are expensive and managed by specialized companies. This paper is focused on personal computers which are available in most homes and can be used to control home electronic appliances and home security facilities. We implemented a home automation server based on Linux. The standard parallel port of personal computer is used to connect sensors and actuators. Therefore, the cost of the server is very low. Moreover, the server is connected to Internet and anywhere we can control and monitor the home security facilities and home automation systems.

Home appliance manufacturers have recently been trying to provide smart products capable of various Internet services. For example, one health care manufacturer provides a Wi-Fi-capable scale. Once users register their information with the manufacturer's server, their weight and body fat records are automatically uploaded to the server whenever they measure their weight. The users can then watch and check their weight log easily using a smart device, such as a smartphone or tablet. One of the biggest problems, however, is that the initial configuration of the appliances and the user registration process may be quite complicated to typical users who are unfamiliar with such IT devices. This paper proposes an autoconfiguration system structure and protocol for Internet-capable home appliances, which supports the initial configuration and remote maintenance service of the device with only little user effort. Manufacturers can develop their own information appliances and provide differentiated services using the proposed system and protocol.

We describe CHAP authentication for roaming service method of visited ISP subscriber on GPRS network. We also illustrate how visited mobile ISP subscriber can access ISP server and authenticate RADIUS in home network via Gateway GPRS Support Node (GGSN) on GPRS/UMTS network for wireless internet service and roaming. For this we propose the modified CHAP message format, PCO Message format at MT, and interworking message and format between GGSN and RADIUS in home ISP network for wireless internet service of mobile ISP subscriber at GPRS network in this paper. We also show authentication results when visited mobile ISP subscriber via CHAP at GPRS network accesses the RADIUS server in home ISP network.

This paper describes an experimental embedded tiny web server system that monitors the processing of manufacture using the Internet. The object of this study is developing of an embedded tiny web server that connects the stand-alone machines in factory to the Internet. Using the World Wide Web (WWW), we proffer user-friendly environments to users. Anyone with a web browser may easily access the processing of manufacture in the factory. Through connecting different network system, our web server extends the private networks to the Internet, the global networks. Our embedded tiny web server is ideal for process control, building and facility management system, factory automation and even home automation.

The intelligent PVR(Personal Video Recorder) is an enhanced PVR that provides viewers with some advanced features as well as pause, instant replay, search and skip forward found in conventional PVRs. By embedding a home server into a PVR, it is possible for an intelligent PVR to provide a powerful web-based management user interface constructed using HTML, graphics and other features common to web-browsers. When applied to other embedded systems, web technologies offer graphical user interfaces which are user-friendly, inexpensive, cross-platform and network-ready. It is the purpose of this paper to introduce implementation of intelligent PVR which is control by internet. We present the architecture of an home- server with a simple but powerful web-based network interconnection.

In the paper, the Management Server (MS) is designed and developed in order to overcome 1 imitations in the Residential Gateway (RG). The Proposed MS is composed of the Network Management System(NMS), Home Automation System(HAS), Persistent Data Management(PDM). The developed MS is a dedicated server which manages both individual RG and internet home appliances implemented at a home-network environments.

In this paper, we have designed a home network system based on WIPI. WIPI (Wireless Internet Platform for Interoperability) is the standard specification for the mobile platform made by the Mobile Platform Special subcommittee of the Korea Wireless Internet Standardization Forum(KWISP). The system consists of three parts - a server, client, and simulator, and all parts are developed with JAVA. People can control household appliances anytime, anywhere by using cell phones which can use the wireless Internet, so the system offers convenience to people.
