B. D. Gonska,A. Schaumann,S. Purrersymmetric-key primitives so far and it remains an open problem how to build such ciphers..In this work, we propose the MALICIOUS framework, a new method to build tweakable block ciphers that have backdoors hidden which allows to retrieve the secret key. Our backdoor is differential in nature: a spec

In this paper, we present practical distinguishers of the full 6-step version of the underlying permutations of ., namely . and ., solving challenges proposed by the designers on the permutation. We also propose practical forgeri

鞏固

B. D. Gonska,A. Schaumann,S. PurrerWe present several improvements to the framework of differential-linear attacks with a special focus on ARX ciphers. As a demonstration of their impact, we apply them to Chaskey and ChaCha and we are able to significantly improve upon the best attacks published so far.
