The telemedicine applications are the application utilized for the remote monitoring and health assessment of the people living in the remote areas. The networks of the doctors and the field executives utilizes the various kinds of the healthcare sensors for the health checkup of the people by collecting and transmitting over the internet for the treatment of the affected ones. The information being propagated through the internet between the healthcare sensors and the online server model is always prone to the several forms o the attacks. In this paper, the proposed model has been designed to improve the level of security over the telemedicine network. The proposed model will be improved by using the robust encryption with the highly scrambled authentication key. The performance of the proposed model will be assessed under the various performance parameters which define the network health as well as the security level.
