Fortifying IoT Against Quantum Threats: Strategies for Securing Connected Devices in the Quantum Era

All data sent to and from IOT devices, (as well as any data held), must be encrypted in order to enhance the security of IOT devices. At the moment, elliptic curve cryptosystems (ECCs) are used as fundamental building blocks to secure communication in the Internet of Things. Yet, forthcoming quantum computers can quickly compromise public key systems like ECC. We should take action right away to get the IOT ready for the quantum future due to recent developments in quantum computing. This paper at first will give a brief overview on Crystal - Kyber, SIKE and BIKE algorithm which are among the NIST's third round candidate. Then the comparison of these three on the basis of key size, computational power and memory requirement. Finally a recommendation on the most suitable algorithm for making IoT secure in quantum world.
