Postquantum Cryptography

Lucie Popelová

In the last decades there has been such a fundamental development in the technologies including postquantum technologies. It is necessary to focus on postquantum cryptography which is able to resist quantum attacks and secure our systems. This work deals with postquantum protocols that are analysed and measured on the IoT device. Our experimental results are used to find the most effective postquantum protocol for key exchange suitable for IoT.

Because of public-key cryptography’s relevance and quantum computers’ increasingly realistic threat to this technology, it’s necessary to come up with practical and secure postquantum cryptography. This special issue aims to present the state of the art and the grand challenges in postquantum cryptography and to discuss the transition of real-world systems to the new technology.

This is part 2 of IEEE Security & Privacy magazine’s special issue on Postquantum Cryptography. As explained in the introduction to part 1, public-key cryptography is indispensable for the security of open computer networks, particularly the Internet. Because of public-key cryptography’s relevance and quantum computers’ increasingly realistic threat to this technology, it’s necessary to come up with practical and secure postquantum cryptography—that is, public-key cryptography that can be expected to resist quantum computer attacks.
