Abstract : Since the introduction of the LLL algorithm in 1982, lattice reduction has proved to be one of the most powerful and versatile tools of public key cryptanalysis. In particular, it has sometimes been combined with fault injection to break physical implementations of public key cryptosystems. We present several examples of lattice-based fault attacks against DSA and RSA signatures, together with the necessary mathematical background.
