Securing U-Healthcare Sensor Networks using Public Key Based Scheme

Abstract

 Recent emergence of electronic culture uplifts healthcare facilities to a new era with the aid of wireless sensor network (WSN) technology. Due to the sensitiveness of medical data, austere privacy and security are inevitable for all parts of healthcare systems. However, the constantly evolving nature and constrained resources of sensors in WSN inflict unavailability of a lucid line of defense to ensure perfect security. In order to provide holistic security, protections must be incorporated in every component of healthcare sensor networks. This paper proposes an efficient security scheme for healthcare applications of WSN which uses the notion of public key cryptosystem. Our entire security scheme comprises basically of two parts; a key handshaking scheme based on simple linear operations and the derivation of decryption key by a receiver node for a particular sender in the network. Our architecture allows both base station to node or node to base station secure communications, and node-to-node secure communications. We consider both the issues of stringent security and network performance to propose our security scheme.

Authenticated Privacy Preserving Pairing-Based Scheme for Remote Health Monitoring Systems

“…While the performance comparison has shown that our Table 3. Performance comparison between proposed scheme against schemes in [13] and [15]. …”

“…They applied symmetric encryption and RSA algorithm to complete the encryption and authentication for PHI. Hasque et al [15] proposed a secure u-healthcare sensor networks using public key based scheme. In their scheme, they adopted asymmetric encryption for confidentiality protection.…”

Cooperative and Competitive Effect in Heterogeneous Networks of Healthcare System

“…Then, we obtain 12 12 1 3 31 31 21 21 2 3 32 32 3 12 12 21 21 Then, we obtain k and w . If 0 k  , 0 kl w , then 8 q is a stable point. This shows that the network system is stable, and the cooperative effect on the partner network is bigger than the competitive effect on the partner network or that the competitive effect is so small that it cannot induce the coalition system fluctuation.…”

Distributed Authentication Mechanism for Secure Channel Establishment in Ubiquitous Medical Sensor Networks

“…In this section, we introduce various MSN-adaptive solutions since existing security mechanisms adopted in traditional networks such as wireless sensor networks [6][7][8] cannot be directly used in MSNs owing to characteristics of bio-sensors. Some solution for bio-data integrity and freshness exploit biometric information [9][10][11][12] and a symmetric key [13][14][15] or a public key [16,17].…”
