确保安全性在智能家居环境中至关重要,只有授权用户才能访问家庭设备。在过去的十年中,研究人员一直专注于开发访问控制策略,并评估其在防止未经授权的访问方面的有效性。基于角色的访问控制(RBAC)的一个新变体,称为扩展的广义基于角色的访问控制(EGRBAC),最近被引入来捕获智能家居环境中普遍存在的复杂的用户-设备-上下文交互。在本文中,我们证明了分析管理EGRBAC策略的安全性的任务,可以通过减少它的安全性分析的管理RBAC策略。我们还对一个现实的智能家居进行了案例研究,以证明我们的方法在可用性和权限升级等安全要求方面的可行性。
Ensuring security is crucial in smart home settings, where only authorized users should have access to home devices. Over the past decade, researchers have focused on developing access control policies and evaluating their efficacy in preventing unauthorized access. A new variant of Role-Based Access Control (RBAC), called Extended Generalized Role-Based Access Control (EGRBAC), has recently been introduced to capture the intricate user-device-context interactions that are prevalent in smart home environments. In this paper, we demonstrate that the task of analyzing administrative EGRBAC policies for security can be performed by reducing it to the security analysis of administrative RBAC policies. We also conducted a case study on a realistic smart home to prove the viability of our approach with respect of security requirements such as availability and privilege escalation.
