Access control for local personal smart spaces

摘要

As computer systems grow more compact, powerful and cheap to produce, they become more pervasive in society. Smart devices enable users to compute and share resources on the go. Services such as Wi-Fi Direct allow for the creation of device-to-device networks, of a peer-to-peer nature, deemed “smart spaces”. Smart spaces are capable of providing an access-point-less means to share information and resources between their peers. Recent research points to the personalisation of smart spaces, making their management more challenging. Personalised smart spaces, advanced as they may be, introduce new security challenges such as secure resource sharing. This paper consequently evaluates a family-related scenario then a LPSS access control framework is proposed, with a focus on the specific nature of LPSS environments namely, local and global sets of rules defined in local and global policies. Finally, access control rules are presented, with respect to the motivating scenario, to illustrate the operation of access control enforcement using local and global policy rules.
