A Secure System For Pervasive Social Network-Based Healthcare

Abstract

Modern technologies of mobile computing and wireless sensing prompt the concept of pervasive social network (PSN)-based healthcare. To realize the concept, the core problem is how a PSN node can securely share health data with other nodes in the network. In this paper, we propose a secure system for PSN-based healthcare. Two protocols are designed for the system. The first one is an improved version of the IEEE 802.15.6 display authenticated association. It establishes secure links with unbalanced computational requirements for mobile devices and resource-limited sensor nodes. The second protocol uses blockchain technique to share health data among PSN nodes. We realize a protocol suite to study protocol runtime and other factors. In addition, human body channels are proposed for PSN nodes in some use cases.The proposed system illustrates a potential method of using blockchain for PSN-based applications.INDEX TERMS IEEE 802.15.6, blockchain, e-health, healthcare, human body channels.

Secure Caching Scheme by Using Blockchain for Information-Centric Network-Based Wireless Sensor Networks

“…On the other hand, there are proposals of WSN systems secured with the blockchain technique [14]- [16]. Zhang et al [14] and Dorri et al [15] proposed a secure home network system in order to share secure health data by using pervasive social network nodes, such as smartphones, tablet computers, and personal computers.…”

“…Zhang et al [14] and Dorri et al [15] proposed a secure home network system in order to share secure health data by using pervasive social network nodes, such as smartphones, tablet computers, and personal computers. Banerjee et al [16] surveyed the existing security approaches in the Internet of Things domain, and categorized and discussed them into two types (reactive and proactive solutions).…”

“…On the other hand, the blockchain mechanism is not suitable for resource-constrained WSN devices since the mining task in the verification process requires burdensome computer calculations. To overcome this issue, in the related works [14]- [16], the mining task is performed on cloud servers; however, we are deeply concerned about ensuring the safety of the blockchain-based ledger against the wellknown 51% attack-the blockchain can be illegally rewritten when a malicious miner group occupies over 50% or the larger due to the open and free mining environment. On the other hand, the proposed scheme can construct and provide an unopened (closed) mining network on a WSN system by using the overlay concept to solve the above problems of the necessity of computer resources and the 51% attack.…”
