Side Channel Analysis and Lattice Attacks

Abstract: Lattice attacks are a typical endgame for side channel attacks targeting digital signature schemes. During the procurement phase, the attacker queries digital signatures, messages, and corresponding side channel traces, then tries to extract secret information from these traces and apply lattice methods to recover the private key. But in practice, these traces are often incomplete and/or noisy, complicating theoretical models for applying lattices. In this talk, I discuss some of the lattice attack techniques developed over the years, and outline a few interesting open problems that highlight the gap between theory and practice for applied side channel attacks powered by lattice methods.
