In this paper, we propose two attribute-oriented authentication and transmission schemes for secure and privacy-preserving health information sharing in health social networks (HSNs). HSN users are tagged with formalized attributes. The attribute-oriented authentication scheme enables each HSN user to generate an attribute proof for itself, where its(More)
Wireless Body Area Network (WBAN) is gaining popularity due to its large scale of applications in eHealth. Due to its critical and real-time nature, eHealth care system must provide security, privacy, and quality of service (QoS) support, in order to provide an efficient, valuable and fully reliable assistance to patients. This paper studies packet(More)
In this paper, we propose an efficient and secure patient-centric access control (PEACE) scheme for the emerging electronic health care (eHealth) system. In order to assure the privacy of patient personal health information (PHI), we define different access privileges to data requesters according to their roles, and then assign different attribute sets to(More)
—In this paper, we propose a secure data-forwarding scheme, called SATS, for delay-tolerant wireless networks. SATS uses credits (or micropayment) to stimulate the nodes' cooperation in relaying other nodes' messages and to enforce fairness. SATS also makes use of a trust system to assign a trust value for each node. A node's trust value is high when the(More)
We consider the problem of patient self-controlled access privilege to highly sensitive Personal Health Information (PHI), where PHI is expected to be securely stored in cloud storage for uninterrupted anytime, anywhere remote access. In order to assure the privacy of PHI, we propose Efficient and Secure Patient-centric Access Control (ESPAC) scheme which(More)
Wireless Body Area Networks (WBANs), as a promising health-care system, can timely monitor human physiological parameters. Due to the limitation of communications, power, storage and computation in WBANs, a cloud assisted WBAN flourishes and provides more reliable, real-time, and intelligent health-care services for patients and mobile users. However , it(More)
—In this article, we introduce a novel Remote Health Monitoring (RHM) system to enable high-quality pervasive healthcare services to users with low delivery delay and reduced costs. We define the RHM architecture and summarize the design considerations. We then present a promising commercialized solution, ViiCare, with system infrastructures and supporting(More)

In this paper, we propose a delay-tolerant secure long-term health care scheme, RCare, for collecting patient's sensitive personal health information (PHI). Specifically, to minimize the overall health care cost, RCare provides network connectivity to rural areas using conventional transportation vehicles (e.g., cars, buses) as relay nodes. These vehicles(More)
