Secure middleware in ubiquitous healthcare

Recent advancement in ubiquitous healthcare evolves to new challenges in ubiquitous communications. Secure communication in wireless sensor networks (WSNs) is one of the important issues, especially, when WSN comes to ubiquitous healthcare, where security is main requirement in sensor devices, communication and continuous real-time monitoring of patient in hospital or home network. WSN requires efficient and automated secure communication between distributed applications running upon them. Existing middleware approaches to secure communication cannot satisfy the advanced requirement in wireless sensor network. In this paper we proposed a secure progressive middleware which certainly enhance the quality of data transfer, provides secure communication and also improve the quality of service with several modules. This middleware composed on different medical sensors (tri-axial accelerometer, ECG and temperature) and healthcare application module In addition, to protect critical sensor data from unauthorized access has been considered one of the basic goal of this middleware which is achieved by implementing a PingPong-128 stream cipher algorithm in data communication from sensor devices to application modules. With this prototype a secure middleware is presented and implemented in this paper with several other measurements such as performance, portability, scalability and security.
