  Cool+Cruel = Dual
  Recently Wenger et al. (IEEE S&P 2025) claimed that the `Cool and Cruel' (C+C) approach to solving LWE with sparse secrets (Nolte et al., AFRICACRYPT 2024) outperforms other approaches, in particular the well established primal attack. In this talk I’ll show that 1) C+C is an instantiation of a known dual attack (Albrecht, EUROCRYPT 2017), 2) experimental evidence that the primal attack can outperform C+C in similar regimes to those studied by Wenger et al.
