Abstract: The impending realization of scalable quantum computers has led to active research in quantum-resistant cryptography. Amongst various classes of quantum-resistant cryptography schemes, lattice-based cryptography is emerging as one of the most viable, almost half of the 'survivors' of second round of the NIST PQC are lattice based in construction! This work discusses the next natural step on the road to their practical deployment, i.e., addressing the physical security of lattice-based cryptographic implementations on various platforms. This talk surveys the state-of-the-art in terms of side channel attacks (SCA), both invasive and passive attacks, and proposed countermeasures. Although the weaknesses exposed have led to countermeasures for these schemes, the cost, practicality and effectiveness of these on multiple implementation platforms, however, remains under-studied.
