A Secure Multi-factor Authentication Protocol for Healthcare Services Using燙loud-based SDN

Cloud-based SDN (Software Defined Network) integration offers new kinds of agility, flexibility, automation, and speed in the network. Enterprises Cloud providers both leverage benefits as networks can be configured optimized based on application requirement. The cloud paradigms has played an indispensable role improving ubiquitous health care services. It improved real-time monitoring patients by medical practitioners. Patients’ data get stored at central server from where it is available to practitioners no time. centralisation makes more vulnerable malicious attacks causes a major threat patients’ privacy. In recent days, several schemes have been proposed ensure safety data. But most techniques still lack practical implementation this paper, secure multi-factor authentication protocol using hash function proposed.
