Abstract Information security has become an important issue in the modern world due to its
increasing popularity in Internet commerce and communication technologies such as the …

Cryptographic algorithms play an important role in the security architecture of wireless
sensor networks (WSNs). Choosing the most storage-and energy-efficient block cipher is …

We present a 5-round distinguisher for AES. We exploit this distinguisher to develop a meet-
in-the-middle attack on 7 rounds of AES-192 and 8 rounds of AES-256. We also give a time …

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 …

In this paper we apply impossible differential attacks to reduced round AES. Using various
techniques, including the early abort approach and key schedule considerations, we …

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 …

Abstract Impossible Differential Cryptanalysis (IDC)[4] uses impossible differential
characteristics to retrieve a subkey material for the first or the last several rounds of block …

In 2000, Biham and Keller [Cryptanalysis of reduced variants of Rijndael, 3rd AES
Conference, in press] presented an impossible differential cryptanalysis of the Advanced …

In this note we study security of 128-bit key 10-round AES against the boomerang attack. We
show attacks on AES reduced to 5 and 6 rounds, much faster than the exhaustive key search …

In this paper, we present some new results on impossible differential cryptanalysis of
reduced AES, which update the best known impossible differential attacks on reduced AES …
