In the ubiquitous computing environment, service providers should able to deliver their services to various devices, such as PDA Smart Phone, Telematics devices. For this, W3C announced 'Composite Capabilities/Preference Profile (CC/PP) Standard' for delivery-context description. But at present, only a small number of mobile phone supports the CC/PP standard, most of contents servers do not support the CC/PP profiles. In this paper, a rule-based CC/PP profiling method in ubiquitous environment is developed. A rule-based profiles are generated by analyzing request headers which are received from various ubiquitous devices. Service providers can use these profiles to provide optimized services to the various devices which have different capabilities.

The server system of digital contents has to how the context information about client devices to provide the appropriate contents for each device effectively. CC/PP standard specification is an agreement for describing and transmission of the information related with a client device. In this case, the information on device hardware and software, networks and user's preference is included here. In the mean time, WAP forum defined W-HTTP protocol to transmit the CC/PP profile information of a client device to a server system. However, the client devices which use existing HTTP protocol to transmit their information cannot provide the CC/PP profile information to a server. In this paper, we propose an effective method to create and provide the CC/PP profile in the clients which use not only HTTP protocol but also W-HTTP protocol to transmit device information.

최근 CCRA(Common Criteria Recognition Arrangement) 협정서 개정에 따라 공통평가기준인 CC(Common Criteria) 평가제도에 변화가 생기고 있다. 현재의 CC 평가제도가 가지는 한계를 보완하고자 PP(protection profile)를 대신하는 cPP(collaborative protection profile)가 개발되었는데, 기존의 폐쇄적으로 운영되던 PP 개발 프로세스와 달리 cPP 개발에는 CCRA 회원국의 여러 기관 및 기업이 적극적으로 개발에 참여할 수 있다. 따라서 현재 세계 각국에서 cPP 개발에 관한 논의가 활발히 진행되고 있으며 세분화된 연구도 요구되고 있다. 본 논문에서는 기존의 CC 평가제도가 가지는 한계를 살펴보고 이러한 한계를 극복하기 위한 cPP의 등장 및 개정되는 새로운 CC 평가제도의 운영을 분석한다.

A development of PP/ST is essential in CC environment. And, the KOREA is expected that PP/STs demand increases explosively by joining to CCRA hereafter. Specially, PP/ST development experience of the KOREA is lacking. So, development of security environment(assume, threat, policy) and security objective contents refer only PP/ST Guide(ISO/IEC PDTR 15446) are very difficult. In this paper, we propose a web service based common security environment and security objective repository model that make developers can run PP/ST creation to be simple. Through proposed model, developers who development experience is lacking are expected to achieve PP/ST development to be simple.

This paper presents a new assumptions statement generation method for developing TOE security environment section of PP. We surveyed on guides on the assumption statement in CC scheme, and collected and analyzed hundred of assumption statements which are in 26 certified and published real PPs and CC Toolbox/PKB. The CC Toolbox/PKB is included a class of pre-defined assumption statements. From the result of the survey, we developed a new generic assumption statement list, and proposed a assumption derivation method by using the list.

This paper presents a transcoding method that dynamically adapts Web pages to various devices. The proposed method is based on a CC/PP profile that is a standard description of a device's context information. Additionally, to support a sophisticated transcoding, we define an annotation schema for representing additional information about original contents. Since a mobile device has a screen of limited size, A Web page is splitted into many small ones. Our method constructs a navigation-map that represents the hierarchical relations among the splitted pages. Experimental results with various Web contents show that the proposed method is superior in terms of user's convenience of navigation and the transcoding Quality.

모바일 디바이스가 널리 사용됨에 따라 이를 통한 웹 컨텐츠의 이용이 증가하고 있다. 그러나 모바일 디바이스를 통하여 기존의 웹 컨텐츠를 이용하는 데에는 한계가 있다. 본 논문에서는 CC/PP 프로파일에 따라 웹 문서를 적절히 가공하여 전송하는 트랜스코딩 방법을 제안한다. 제안된 방법은 보다 정교한 수준의 맞춤형 서비스를 지원하기 위하여 원본 문서에 애노테이션(annotation)을 기술할 수 있는 방법을 지원한다. 제안된 애노테이션은 모바일 디바이스에서 표시할 수 없는 컨텐츠를 임의의 리소스로 대체할 수 있다. 또한 제안된 방법은 디바이스의 스크린 사이즈를 고려하여 컨텐츠를 적절한 크기로 나누어 보여주며, 문서의 구조를 효과적으로 전달하기 위한 내비게이션 맵을 제공한다.

통신 기술과 모바일 기술의 발달로 인해, 이 두 기술을 융합된 모바일IPTV가 탄생하였다. 하지만, 모바일IPTV는 기존의 IPTV와는 달리 방대한 종류의 디바이스와 그에 따른 제공하는 비디오 포맷과 같은 제약들이 존재한다. 하지만 기존의 서비스는 다양한 이기종의 모바일 장치의 특성을 고려하지 않고 서비스 제공자가 모든 사용자에게 같은 서비스를 제공하기 때문에 사용자는 콘텐츠의 포맷이나 용량으로 인하여 장치에 알맞은 컨텐츠를 받지 못할 경우가 있으며 혹은 신속하게 서비스를 제공받지 못할 경우가 있다. 위와 같은 문제를 해결하기 위해서, 본 논문에서는 CC/PP(Composite Capabilities / Preference Profile)를 이용하여 이기종의 모바일IPTV 장치들의 규격 및 특성을 분석하고, 이를 통해 다양한 기종의 모바일IPTV 사용자들에게 장치의 특성에 맞는 맞춤형 서비스를 최적화하여 제공할 수 있는 시스템을 제안한다.

In this paper, the management architecture and the ubiquitous profile based on CC/PP for contents adaptation in the ubiquitous environment is designed. The components and the attributes of the ubiquitous profile are defined based on the services scenario of contents adaptation in the ubiquitous environment. The ubiquitous profile was applied to techniques such as standard vocabulary, CC/PP structure, RDF schema and RDF to use effectively in the ubiquitous environment during the design. Also we design and propose the another management architecture based on ideas such as the dynamic constitution method, the metadata constitution method using a repository and the management method of gateway on center for the effective management of the ubiquitous profile. The result of performance evaluation for the proposed management architecture is more effective compared with the previous management method of the profile. The proposed the ubiquitous profile and the management architecture has provided the foundation of the research for a user to adaptation contents services in the ubiquitous environment.

A Protection Profile(PP) is a common security and assurance requirements for a specific class of Information Technology security products such as firewall and smart card. A PP should be included "TOE(Target of Evaluation) Security Environment", which is consisted of subsections: assumptions, treat, organizational security policies. This paper presents a new threats statement generation method for developing TOE security environment section of PP. Our survey guides the statement of threats in CC(Common Criteria) scheme through collected and analysed hundred of threat statements from certified and published real PPs and CC Tool Box/PKB that is included a class of pre-defined threat and attack statements. From the result of the survey, we present a new asset classification method and propose a threats statement generation model. The former is a new asset classification method, and the later is a production rule for a well formed statement of threats.
