This work introduces XMSS-T, a new stateful hash-based signature scheme with tight security. Previous hash-based signatures are facing a loss of security, linear in performance parameters such as the total tree height. Our new scheme can achieve the

This paper shows that it is feasible to implement the stateless hash-based signature scheme SPHINCS-256 on an embedded microprocessor with memory even smaller than a signature and limited computing power. We demonstrate that it is possible to generat

Rounded Gaussians : fast and secure constant-time sampling for lattice-based crypto

Autor: Hülsing, A.T., Lange, T., Smeets, K.

This paper suggests to use rounded Gaussians in place of dis- crete Gaussians in rejection-sampling-based lattice signature schemes like BLISS. We show that this distribution can efficiently be sampled from while additionally making it easy to sample

At CRYPTO 2013, Boneh and Zhandry initiated the study of quantum-secure encryption. They proposed first indistinguishability definitions for the quantum world where the actual indistinguishability only holds for classical messages, and they provide a

Bad directions in cryptographic hash functions

Autor: Bernstein, D.J., Hülsing, A.T., Lange, T., Niederhagen, R.F.

A 25-gigabyte "point obfuscation" challenge "using security parameter 60" was announced at the Crypto 2015 rump session; "point obfuscation" is another name for password hashing. This paper shows that the particular matrix-multiplication hash functio

Several lattice-based cryptosystems require to sample from a discrete Gaussian distribution over the integers. Existing methods to sample from such a distribution either need large amounts of memory or they are very slow. In this paper we explore a d
