Chaos is known as a natural candidate for cryptography applications owing to its properties
such as unpredictability and initial state sensitivity. However, certain chaos-based …

Chaos-based cryptosystems have been an active area of research in recent years. Although
these algorithms are not standardized like AES, DES, RSA, etc., chaos-based cryptosystems …

Since Rijndael was chosen as the Advanced Encryption Standard (AES), improving upon 7-
round attacks on the 128-bit key variant (out of 10 rounds) or upon 8-round attacks on the …

In this paper, we revisit meet-in-the-middle attacks on AES in the single-key model and
improve on Dunkelman, Keller and Shamir attacks at Asiacrypt 2010. We present the best …

Linear cryptanalysis, along with differential cryptanalysis, is an important tool to evaluate the
security of block ciphers. This work introduces a novel extension of linear cryptanalysis: zero …

AES is the most widely used block cipher today, and its security is one of the most important
issues in cryptanalysis. After 13 years of analysis, related-key attacks were recently found …

Abstract Impossible differential (ID), zero-correlation (ZC), and integral attacks are a family of
important attacks on block ciphers. For example, the impossible differential attack was the …

While differential behavior of modern ciphers in a single secret key scenario is relatively well
understood, and simple techniques for computation of security lower bounds are readily …

Using a new 4-round impossible differential in AES that allows us to exploit the redundancy
in the key schedule of AES-128 in a way more effective than previous work, we present a …

Zero correlation linear cryptanalysis is a novel key recovery technique for block ciphers
proposed in [5]. It is based on linear approximations with probability of exactly 1/2 (which …
