Enhancement of RK- Blowfish Algorithm for Data Encryption through Block Chain in Healthcare System

Abstract

In this research work, the sensors device to be connected with network/service from everywhere, will receive signal from the biological changes of patients and transfer to the IoT middleware. Such information received by the IoT middleware is uploaded into the internet cloud, where the information is saved for further analysis. The middleware is controlled by IPv6 addressing scheme using Runge-Kutta (RK) Blowfish algorithm by making the modification in Feistel cipher of blowfish through integration of Blowfish and the Runge-kutta method. By this enhancement of RK- Blowfish algorithm, reported as efficient when compared to Advanced Encryption Standard. The healthcare paradigm being the ultimate focus of IoT, it has lot of issues concerning the security, addressing scheme, objects identified and network efficiency. The versatile features of healthcare scheme can be invariably fixed by carefully studying the features.
