The creation of a RFID/USN environment has increased rapidly due to the activation of ubiquitous security environment suitable for RFID/USN environment but has failed to comply with the speed of security threats. Therefore, this thesis presents MSNR suitable for RFID/USN. The MSNR presented showed an increase in the processing rate of 1.3 times compared to the existing AES and showed 2 fold improvement in performance in terms of the overall system efficiency. Therefore, MSNR is considered to be a password algorithm suitable to overcome the conditions of environmental resource conditions, such as RFID/USN.

IPSec is a security protocol suite that provides encryption and authentication services for IP messages at the network layer of the Internet. Key recovery has been the subject of a lot of discussion, of much controversy and of extensive research. Key recovery, however, might be needed at a corporate level, as a from of key management. The basic observation of the present paper is that cryptographic solutions that have been proposed so far completely ignore the communication context. Static systems are put forward fur key recovery at network layer and solutions that require connections with a server are proposed at application layer. We propose example to provide key recovery capability by adding key recovery information to an IP datagram. It is possible to take advantage of the communication environment in order to design key recovery protocols that are better suited and more efficient.

In this paper, we design an authentication model based mobile PKI (Public Key Infrastructure). The authentication mood consists of Root-CA Home-network agent and Foreign-network agent. CA will going to gave the delegation ticket to Home-Agent or Foreign-Agent when they request. The authentication mode information security is various characteristic more then high speed, mobile network and low cost more then previous structure of assure information security.

The development of technology provides and increases security as well as convenience for humans. The development of new technology directly affects the standard of life thanks to smart home automatic control systems. This paper describes a door control, automatic curtain, home security (CCTV, fire, gas, safe, etc.), home control (energy, light, ventilation, etc.) and web-based smart home automatic controller. It also describes the use of ARM (Advanced RISC Machines) for automatic control of home equipment, a Multi-Axes Servo Controller using FPGA (Field Programmable Gate Array) and PLC (programmable logic controller). Additionally, it describes the development of a HTML editor using web auto control software. The tab loading time (7 seconds) is faster when using ARM-based web browser software instead of Chrome and Firefox is used because the browser has a small memory footprint (300M). This system is realized by web auto controller language which controls and uses PLCs that are easier than existing devices. This smart home automatic control technology can control smart home equipment anywhere and anytime and provides a remote interface through mobile equipment.

WWW(World Wide Web)은 미래의 쇼핑수단으로 자리를 잡아가고 있다. 하지만, 현재 사용하고 있는 지불형태는 구매자의 신용카드 정보가 평문으로 네트워크를 통해 전송되는 것과 같은 보안상의 문제점을 가지고 있다. 이러한 문제점들은 개인정보에 대한 침해 딸만 아니라 정제범죄 등의 사회적 문제를 야기할 수 있다. 이러한 문제점을 재결하기 위하여 본 논문에서는 신용카드를 사용하는 새로운 전자지불 프로토콜인 SCCP(Secure Credit Card payment)를 소개한다. SCCP의 적합성을 확인하기 위하여 IBM에서 제시한 기준에 따라 수행한 결과, 본 논문에서 제시하는 방법은 안전한 전자지불 프로토콜로 판단된다.

The area of business applications in the internet are extended enormously in result of fast development of computing and communication technologies, increase of internet use, and use of intranet/extranet in enterprise information system. Widely spread the use of the internet, there are various applications for Business to Business (B to B) or Business to Customer(B to C) model that are based on the intranet or extranet. This paper designed and implemented the Web-based Electronic Bidding System for Business to Business (B to B) model. The technical issues of electronic bidding system in the internet are involved in the connection between web client and server, electronic data interchange for the contract document, and security solution during the bidding and contracting processes. The web-based electronic bidding system in this paper is implemented using Java applet and servlet as a connection interface for web client and server, XML/EDI-based documents for a bid and a contract, and bidding server and notary server for enhancing the security using PKI(Public Key Infrastructure)-based public key cryptography, digital signature and Certification Authority(CA).

Grid is a infrastructure to connect heterogeneous resources that are scattered over areas with high-speed network and to cooperate with each other. To carry out Grid application, first, network resources should be managed, since the network has to be safe and reliable. GMA suggests an effective architecture for monitoring of resources that are scattered over a wide area. In this paper, basing on GMA, Grid network management system based on web for practical and general network management is designed. Grid network management system has to operate and connect various distributed management system. Using LDAP authentication, as one access system, Grid network management system maintain stability.

Currently, internet is deeply rooted in everyday life and many things are performed using internet in real-world, increased internet user because convenience. But then, internet accident is on the increase rapidly. Therefore, it is necessary that testing system generate automatically various attack patterns and traffic. In this paper, we describe method of design and implementation about AGT(attack generation test suite : simulator) system which generate various attack patterns using multiple agents.

This study to solve these problems a search system has been designed by combining the two methods. Also the search and manage image data by handheld devices such as portable PDA or smart phone, a system has been designed application to an embedded system. Once this is used, multimedia data can be efficiently searched and utilized by handheld devices.

In this paper, Integrated development environments interface was designed and implemented for the integrated development environments. By using connection interface, Integration between physical prototyping and virtual prototyping which has different characteristics each other could be possible. Specially, good performance of the connection interface was showed by testing result of operation implemented.
