摘要
在家庭网络环境下,OSGi平台在控制不同用户进行访问时,授权就显得非常重要。OSGi平台虽然支持基于角色的访问控制(RBAC),但并不支持RBAC模型中的所有功能。本文针对OSGi平台动态部署不足的问题,通过增加了相对角色的概念并使用委托模型激活了其访问控制,提出了一个多样化的访问控制机制,扩展了OSGi平台现有的授权机制。
In home network environments, Authorization is especially important when OSGi platform control the access of different users. OSGi platform supports RBAC model but it does not support all of facilities in the RBAC model. To address its limitations for dynamic deployments, this paper extends the existing authorization mechanism of OSGi platform. By adding the relative role concept and activating the access control using the delegation model, proposed mechanism enables a diverse access control.
