Summary of project:

Most current public-key cryptosystems are designed on the assumption that problems related to integer factorization and discrete logarithm are computationally hard. This assumption would immediately collapse with the advent of quantum computers. Lattice-based cryptography has emerged as the most promising solution to address this threat. Our approach is to bring together interdisciplinary expertise in lattices and quantum computing. The broad goal is to understand the quantum resilience of lattice-based cryptography.
