Smart healthcare technologies transform the traditional healthcare system in all possible ways. Smart healthcare has enormous number of benefits over the traditional system. However, at the same time, it also suffers from some healthcare data security and privacy related issues as the potential Internet attackers may get access to the sensitive healthcare through the deployment of various kinds of attacks. To mitigate these issues, in this paper, a new lightweight remote user authentication and key establishment scheme (in short, UAKM-SH) has been proposed by making the use of lightweight cryptographic operations. The security analysis of UAKM-SH is conducted to prove its robustness against various possible attacks. A detailed comparative study among the proposed UAKM-SH and other existing schemes shows that UAKM-SH performs better in terms of computation cost, communication cost, and the offerered security and functionality features. Finally, the testbed implementation of UAKM-SH is given to observe its behaviour in the real time scenario.
