||New Paradigm to Construct Public Key Cryptographic Schemes for Lightweight Devices with Provable Security against Quantum Attackers
||Public Key Cryptographic (PKC) schemes are an essential technology to build secure communication in networks. However, it has been proven that quantum computers can break all current standard PKC schemes, and moreover, the research on developing practical quantum computers has been gaining momentum in recent years. The main goal of this proposed research is to develop a new paradigm based on (1) computational problems in the binary field which
are hard even for quantum computers, and (2) a new framework for proving security against quantum computers, to overcome those flaws and then use it to construct new PKC schemes which require small costs for implementation and are equipped with concrete security proof against quantum computers. As application target, we expect that the results of this project can be applied to secure communication between lightweight devices against quantum computers in networks comprising a large variety of devices such as the Internet of Things (IoT).
