Excogitation of secure data authentication model for wireless body area network

This paper outlines the implementation of a secure data authentication model for the wireless body area network using a single private key exchanged during the time of configuration. The need for secure data exchange grows rapidly due the fact that the data exchanged are confined to the details of the ailing patient. Recent researchers have proposed a secure system for WBAN, but there is a huge demand to incorporate the security parameters into it. A system in place must ensure security with the use of limited amount of resources. This paper tries to address these issues of security considering the fact of limited availability of resources like power, bandwidth, thereby helping to achieve, more secure and time-efficient system in place for the effective online health monitoring scheme using WBAN. Also the security system for WBAN is proposed with low computational complexity for the secure transaction using a key utilized cryptographic encryption algorithm.
