In this paper, we propose adaptive convergence security policies and management technologies to improve security assurance in the home networking environment. Many security issues may arise in the home networking environment. Examples of such security issues include the user privacy, the service security, the integrated networking security, the middleware security and the device failure. All these security issues, however, should be fulfilled in phase due to many difficulties including deployment cost and technical complexity. For instance, fundamental security requirements such as authentication, access control and prevention of crime and disaster should be addressed first. Then, supplementary security policies and diverse security management technologies should be fulfilled. In this paper, we classify these requirements into three categories, a service authentication, a user authentication and a device authentication, and propose security policies and management technologies for each requirement. Since the home gateway is responsible for interconnection of many home devices and external network access, a variety of context information could be collected from such devices.

This paper describes the system which provides home entertainment services to users using the middleware-cooperation module which makes UPnP and ACAP cooperate with each other. UPnP or ACAP providespowerful functionalities to its own network to play multimedia contents using its own resources. U one middleware uses the information and the resources of another middleware, itcould provide services with more contents and more powerful functionalities than those which it originally provides. This paper develops the middleware-cooperation module to make two middleware cooperate with each other and use resources of another middleware. The middleware-cooperation module makes UPnP and ACAP cooperate with each other, and it makes them share their information and resources without resource collision.

In an environment of home network where a number of technologies including heterogeneous hardware platforms, networking and protocols, middleware systems, and etc, exist, OSGi provides a platform for deployment and sharing of services managed in hardware and guarantees compatibility among applications. However, only simple control and processing of event data are considered in a home network using OSGi, and the consideration about real time processing of data stream generated by sensors is not enough. Therefore, researches allowing users to effectively develop OSGi applications by using various kinds of sensors generating data streams in the home network environment using OSGi are needed. In this paper, we propose an effective method of processing various types of real time data streams supplied to OSGi applications, including filtering, grouping, and counting, etc.

최근에 홈네트워크 분야에서 각 서비스의 특징에 따라 UPnP, HAVi, Jini등과 같은 다양한 홈네트워크 미들웨어들이 생겨나게 되었고 이들을 통합하기 위한 연구가 진행되고 있다. 대부분의 홈네트워크 미들웨어를 통합하려고 하는 연구들은 크게 두 가지의 문제점을 가지고 있다. 먼저 사용자가 가정 내에 홈네트워크 시스템을 구축하고자 할 때 그 비용이 사용자에게 너무 부담이 된다는 것이다. 또 다른 문제점은 시스템 구축 후에 새로운 홈네트워크 미들웨어가 추가될 때 이미 구축되어 있는 시스템과의 호환이 너무 어렵다는 것이다. 이런 문제점을 해결하기 위해 XML을 이용한 VHG 기반 메타컴퓨팅 미들웨어를 설계하였다. 이 홈네트워크 메타컴퓨팅 미들웨어를 XBI-Middleware(XML-based Integration Middleware)라 부른다. XBI-Middleware는 특정 홈네트워크 미들웨어를 사용하는 디바이스와 전혀 다른 홈네트워크 미들웨어 사용하는 디바이스 간에 정보 메시지의 전달을 위해서 프로토콜 변환에 용이한 XML을 사용하기 때문에 홈네트워크 미들웨어간의 정보 전달에 있어서 용이하고 추가적인 비용에 대한 부담감이 없다. 이 논문은 XML을 이용하여 다양한 홈네트워크 미들웨어를 통합하고 새로운 홈네트워크 미들웨어가 추가 되었을 경우 효율적으로 재통합 할 수 있는 방법을 제안한다.

Recently, public home have used a more than two computer connected with network, and several home appliances using independently with internet or network are developing to be related closely with the network. Therefore, the home utilized for a simple terminal of the global network in the past is being expanded to another part of the sub network. For a variety of connecting home-area protocols with the existing existing network, we require a new Residential Gateway(RG) that does not only make the home-area network operating in the sub network but also connects to the external network. In this paper, RG has intrinsic limits against flexible service due to IP address assignment and hardware capacity. In order to solve this problem in the RG, we propose a Management Server(MS). The MS that offers the integrated managements and control services for a variety of devices connected the RG in the home-area. It can not only solve the dynamic IP address assigning problem but also assigns private IP addresses to the home network devices through the Network Address Translation(NAT). It also provides somewhat useful functions for the home network and the RG for other additional services. <중략> The MS is using a SNMP protocol for managing the RG in the domain, a polling method of the MS and the RG compose a sequence polling method, a polling method using a multi-process and a multi-thread. In this paper, we introduce a problem with polling method separately, show a polling method between the MS and the RG using a multi-thread.

Ubiquitous network consists of various devices using several heterogeneous protocols and requires seamless communication between devices. This paper proposes a new hierarchical event service and multiple event server architecture to implement the service under ubiquitous environment. The proposed event service classifies devices by logical and physical location to abstract the idiosyncrasy of used protocols, and reduces network load. Due to the design consideration, the proposed architecture removes transfer of duplicated event data effectively. As a result, we can guarantee the reliable event delivery. The prototype multiple event server architecture was implemented according to the proposed idea and evaluated its performance under a home network test bed.

홈 네트워크는 가정 내에서 여러 기기들을 유 무선으로 연결 후 네트워크를 구성하여 서로 데이터를 공유한다. 가정 내 기기들은 컴퓨팅 기능이 저하되기 때문에 보안취약점을 이용한 사이버 범죄에 노출되어 있다. 따라서 사이버 범죄 및 개인정보의 유출을 방지하기 위해 유 무선 보안취약점 및 대응방안을 파악할 필요가 있다. 본 논문은 홈 네트워크의 보안 개선을 위해 미들웨어의 보안기능 및 홈 네트워크의 보안취약요인을 분석하고, 보안취약점 개선 방안을 제안한다.

Most security solutions and middleware on home network consider internet users as approaching subject. It is unrealistic where the most subjects are mobile users who want to control home network devices. Therefore minor and fast certification structures are needed to control other devices with mobile device that has lower computing capacity. To solve the above problems, this paper wants to build safe certification frame work for internet and mobile users to control household devices safely. New certification structure is proposed to get out of heavy certification structure like PKI and to minimize encrypting and decrypting operation by compounding session key and public key.

This paper proposes the construction of intelligent home network system using Power Line Communication(PLC) technique, which allows for UPnP bridge remote control and monitoring based on TCP/IP. Also, the communication for control module inside intelligent home network systems is designed with Simple Control Protocol (SCP) in which each device is connected to be controlled independently. When new UPnP device is additionally installed in intelligent home network systems, it is monitored through UPnP bridges based on its registered UPnP device information. The device control based on PLC and implementation of each UPnP device are effectively managed by using TCP/IP remote control and it's provided fundamental functions to monitor various device information in the home network.
