Deep Learning Side-Channel Collision Attack
Transactions on Cryptographic Hardware and Embedded Systems, 2023 With the breakthrough of Deep Neural Networks, many fields benefited from its enormously increasing performance. Although there is an increasing trend to utilize Deep Learning (DL) for Side-Channel Analysis (SCA) attacks, previous works made specific ...

Revisit two memoryless state‐recovery cryptanalysis methods on A5/1
IET Information Security, 2023 At ASIACRYPT 2019, Zhang proposed a near collision attack on A5/1 claiming to recover the 64‐bit A5/1 state with a time complexity around 232 cipher ticks with negligible memory requirements.

New hash function based on C-MD structure and chaotic neural network
网络与信息安全学报, 2023 In recent years, widely used hash algorithms such as MD5 and SHA-1 have been found to have varying degrees of security risks.The iterative structure of the SHA-2 algorithm is similar to that of SHA-1, making it vulnerable to attacks as well.Meanwhile ...

Finding Collisions against 4-Round SHA-3-384 in Practical Time
IACR Transactions on Symmetric Cryptology, 2022 The Keccak sponge function family, designed by Bertoni et al. in 2007, was selected by the U.S. National Institute of Standards and Technology (NIST) in 2012 as the next generation of Secure Hash Algorithm (SHA-3).

Collision Based Attacks in Practice [PDF]
2015 Euromicro Conference on Digital System Design, 2015 Chosen-Message Simple Power Analysis, also called Collision Based Attacks (CBA), have been proposed by Fouque, Yen and Homma. These attacks aim at inducing and detecting collisions during modular operations. However, detecting collisions is a challenging task in real environments. Doing it in an automated manner is even more challenging. In this paper,

IACR Transactions on Symmetric Cryptology, 2020 Fast Near collision attacks on the stream ciphers Grain v1 and A5/1 were presented at Eurocrypt 2018 and Asiacrypt 2019 respectively. They use the fact that the entire internal state can be split into two parts so that the second part can be recovered from the first one which can be found using the keystream prefix and some guesses of the key materials.

Collision attack on reduced-round Camellia [PDF]
Science in China Series F, 2005 Camellia is the final winner of 128-bit block cipher in NESSIE. In this paper, we construct some efficient distinguishers between 4-round Camellia and a random permutation of the blocks space. By using collision-searching techniques, the distinguishers are used to attack on 6, 7, 8 and 9 rounds of Camellia with 128-bit key and 8, 9 and 10 rounds of ...

Enhancing Collision Attacks [PDF]
, 2004 Side Channel Attacks (SCA) have received a huge interest in the last 5 years. These new methods consider non-cryptographic sources of information (like timing or power consumption) in addition to traditional techniques. Consequently block ciphers must now resist a variety of SCAs, among which figures the class of “collision attacks”.
