본 논문에서는 OSGi서비스 프레임워크 환경에서 서비스의 접근 통제 기법을 구현할 수 있는 정형화된 보안 모델을 제시하고 있다. OSSEM(OSGi Service Security Extension Model)이라고 하는 이 보안 모델은 위임, 허가, 거부의 3가지 권한 엔트리를 정의하여 동적으로 설치되는 번들에서 독립적인 보안 정책의 설정을 지원하며, 다른 번들의 정책과 결합될 때 안전한 서비스의 수행을 보장한다. 이 모델은 유연성있는 보안 정책의 설정의 가능하고 OSGi 서비스 프레임워크 환경에서 기존의 Java 2 보안 아키텍처와 쉽게 통합이 가능하므로 번들과 서비스에 대한 접근 통제 뿐만 아니라 OSG 내부 자원의 접관 통제 방안으로도 확장할 수 있다.

In this paper, we proposed service security model and remote management service on OSGi computing environment. The model is used to make access control decisions like permission-based security inside the java2 platform. In model, policies are defined using a flat text file and include bundles. It method granted flexibility and extendability of access control of bundles and services. Also, we proposed service architecture efficiently for remote management service.

In home network environments, the user authentication and authorization associated user's information and usability may be important security issue. The OSGi service platform, a well-known home network gateway already specifies the mechanism of that. The traditional authority method provided OSGi implements simple RBAC(Role Based Access Control) model. This is difficult to support efficient access control. In this paper, we propose the dynamic RBAC model based on OSGi. The proposed method describes the extended framework that manage two roles named as absolute role and relative role, extend existed framework with relative role and propose programming model to enable dynamic access control. Finally, we implement the proposed framework using AspectJ and Java annotation.

Many security issues occur in cloud computing service environment such as authentication, access control, and so on. In this paper, we propose an effective authentication and access control model which provide integrated management and control when we access various resources in cloud computing environment. To address these problems, we suggest a context-aware single sign-on and access control system using context-awareness, integrated authentication, access control, and OSGi service platform in cloud computing environment. And we show design and implementation of context-aware single sign-on and access control system. Also we verified the flexibility and convenience of the proposed system through multi fact based integrated authentication in cloud computing environment. We could provide flexible and secure seamless security service by user context in cloud computing environment.

Security services that support electric energy service gateway require relatively high reliability. In particular, the application services that accompany communications and data are run organically. Each of the security services should support a secure service platform that supports a secure, scalable life cycle for existing services which should be extends security layer of Universal Middleware such as OSGi platform. In this convergence platform, it is the study of security transfer modular services that allow independent life cycle management of systems through Universal middleware. First, It is modular in terms of energy consumption service and data, enabling real-time operation, communications, remote management and applications. Second, the life cycle of the secure module to support the life cycle of secure, delete, start and updating of the security module by applying the security policy module layer concept. It is modular in terms of power generation and accountability, enabling us to distinguish between reliability and accountability in a large volume of data models in the smart grid, the service was intended to be standardized and applied to the security service platform.
