Title:
Some Lattices Attacks on DSA and ECDSA

Authors: Dimitrios Poulakis

Abstract:

In this paper, using the LLL reduction method and computing the integral points of two classes of conics, we develop attacks on DSA and ECDSA in case where the secret and the ephemeral key and their modular inverse are quite small or quite large.
