We show that many symmetric cryptography primitives would not be less safe with
significantly fewer rounds. To support this claim, we review the cryptanalysis progress in the …

Biclique attack is currently the only key-recovery attack on the full AES with a single key.
Bogdanov et al. applied it to all the three versions of AES by constructing bicliques with size …

In recent years, several MILP models were introduced to search automatically for
boomerang distinguishers and boomerang attacks on block ciphers. However, they can only …

The multi-key, or multi-user, setting challenges cryptographic algorithms to maintain high
levels of security when used with many different keys, by many different users. Its …

The field of cryptography continues to advance at a very rapid pace, leading to new insights
that may impact the security properties of cryptographic algorithms. The Crypto Publication …

Cryptographic algorithms are composed of many complex mathematical functions. When
analyzing the complexity of these algorithms, one fixes priory the overall complexity of the …

Kiasu-BC is a tweakable block cipher proposed by Jean et al. at ASIACRYPT 2014
alongside their TWEAKEY framework. The cipher is almost identical to the AES-128 except …

Meet in the middle (MITM) attack is one of the most important and applicable methods for
cryptanalysis of block ciphers. In this paper, a more generalized method for MITM attack is …

Quantitative analyses of the costs of cryptographic attack algorithms play a central role in
comparing cryptosystems, guiding the search for improved attacks, and deciding which …
