Implementation of Secure Health Care Application Using IoT

The main focus of this chapter is on the health care application using the Blowfish and ECC algorithms for providing security to the data. In the current evolving and technophiles world, providing security for healthcare applications is one of the hectic tasks. Security is one of the crucial parameters and it plays an incredible role in IoT to secure details of patients and their health status. As we are having many cryptography algorithms, we have chosen lightweight cryptography algorithms such as Blowfish from symmetric and elliptical curve cryptography from asymmetric. Moreover, a dataset is taken, which consists of details of patients and includes many parameters based on their heart. Our main problem these days is to secure personal details from cyber attacks so using this, we can solve this problem. Furthermore, the reason behind choosing two algorithms is we also want to compare both algorithms by considering the size (plain text and cipher text) of the text and time (encrypt time and decrypt time) taken for whole process while running the code in python and at last, we not only give a solution for securing but also we compare and show, which is best.
