Abstract
Wireless Sensor Networks (WSN) are worthy to use in ubiq- uitous healthcare environments. They provide comfort to patients and make patient monitoring systems more e±- cient. WSN, when applied in ubiquitous healthcare en- vironments, have di®erent characteristics and security re- quirements. Number of sensors is very small as compared to other WSN applications and all nodes are close to each other in the network. Possibility of human intervention in ubiq- uitous healthcare environments and randomness properties of biometric measurements, which are collected in ubiqui- tous healthcare environments, reduce the security require- ments as compared to other WSN applications. Key Man- agement Schemes, proposed for generic WSN, prove to be overly complex and ine±cient for ubiquitous healthcare en- vironments. In this paper, we present TIMAR, which is an e±cient Key Management Scheme speci¯cally designed for ubiquitous healthcare environment
