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, the authors 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. They adopt patients' attribute structures instead of their identities for authentication and preserve identity privacy during patient-to-vendor communication, and they 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.
