Health care is one such area, where WIFI is still not used as the electromagnetic waves affects patients with diseases like neurological disorders, cancers etc. Hence LIFI can be considered the next big technology which causes no harm to patients and also provides more additional features like greater speed and wider spectrum than WIFI. The only problem while transmitting data through it, in hospitals is to make sure that it ensures confidentiality. As a solution for this problem, the model proposed here uses Elliptic Curve Diffie Hellman and Secure Hash Algorithms to provide utmost security. Elliptic Curve Diffie Hellman is used as an asymmetric function that is, it uses two keys which in turn makes it difficult to hack. Secure Hash Algorithm works as an added advantage used mainly for authentication purpose.
