A note on the analysis of Herrmann–May lattices for small exponent RSA

Abstract At PKC 2010, Herrmann and May introduced a lattice-based method using unravelled linearization to achieve the theoretical bound $$d < N^{1- \frac{1}{\sqrt{2}}}$$ d < N 1 - 1 2 for small RSA exponents. In this paper, we identify an error in their asymptotic analysis, revising the bound...
