Title: Lattice-based Post-Quantum Cryptography: From Algorithm to Architecture Design

Speaker:  Prof. Hanho Lee

Affiliation: Inha University, South Korea


The existing public key cryptosystems such as RSA and elliptic curve cryptography play a crucial role in ensuring the confidential and authenticity of communications on the internet and other networks. However, with the rapid development of quantum computers in recent years, the security of these public-key cryptosystems would be completely broken. Due to this concern, post quantum cryptography (PQC) has attracted increasing interest for securing data privacy against potential quantum attacks. Many researchers have begun to investigate PQC to develop cryptographic algorithms that would be secure against quantum computers. The National Institute of Standards and Technology (NIST) third round submissions showed that lattice-based cryptography (LBC) schemes have become promising candidates for future standardization. In this talk, we will introduce the latticed-based PQC algorithm and discuss the design of efficient lattice-based PQC hardware architectures. We will also highlight important algorithm, software implementation, architecture design principles, and methodology that can facilitate an effective design process.
