Cyberattacks on the power grid serve as a reminder that while the smart
Internet of Things (IoT) can help us control our lightbulbs, it also runs the risk of
putting us in the dark if attacked. Many works of literature have recently attempted to
address the issues surrounding IoT security, but few of them tackle the serious dangers
that the development of quantum computing poses to IoT. Lattice-based encryption, a
likely contender for the next post-quantum cryptography standard, benefits from strong
security guarantees and great efficiency, making it well-suited for IoT applications. In
this article, we list the benefits of lattice-based cryptography and the most recent
developments in IoT device implementations.
The Internet of Things (IOT) is a new technology that is anticipated to improve human
lives. According to Cisco research, by 2020, there will be a vast array of IOT devices
that will span every industry, including transportation, healthcare, and smart gadgets
for every aspect of daily life. IOTs are improving user experience by making smart
devices smarter and their services of high quality. The devices' unfettered access to the
whole network makes the IOT's security issues more susceptible. The research paper
will contribute to the presentation of a compiled report on the security issues with IOTs
and the cryptographic techniques utilised to address them.
