Smart community is an emerging Internet of Things application. It supports a variety of high-value automated services such as pervasive healthcare through a multi-hop community network of smart homes in a local residential region. In this paper, we study privacy preserving data communication between patients and an online healthcare provider (referred to as vendor) for efficient remote healthcare monitoring (RHM) in a smart community environment. We adopt patients' attribute structures instead of their identities for authentication and preserve identity privacy during patient-to-vendor communication, and we build a receiver chain among smart homes to enable vendor-to-patient communication and achieve location privacy. The privacy preserving properties of the proposed data communication scheme are analyzed, and its effectiveness and efficiency are demonstrated through extensive simulations.
