Access control with delegation for smart home applications

Abstract

With the emergence of smart home applications, it is important to have flexible access control so that users can create/transfer their permissions in a convenient way. We propose a lightweight authorization protocol with support of a delegation chain in which a user can easily transfer (part of) his/her access rights to smart appliances in the form of a Bloom filter. The security of our protocol is based on the false positive rate of a Bloom filter. A prototype has been built for evaluation.
