Improved Rectangle Attacks on SKINNY and CRAFT [PDF]
The boomerang and rectangle attacks are adaptions of differential cryptanalysis that regard the target cipher $E$ as a composition of two sub-ciphers, i.e., $E = E_{1}\circ E_{0}$, to construct a distinguisher for $E$ with probability $p^{2}q^{2}$ by ...

Impossible Differential Attack on SAND-64 [PDF]
SAND is an AND-RX-based lightweight block cipher proposed by Chen et al. There are two variants of SAND, namely SAND-64 and SAND-128, due to structural differences.

Fast Parallelizable Misuse-Resistant Authenticated Encryption: Low Latency (Decryption-Fast) SIV [PDF]
MRAE security is an important goal for many AEAD applications where the nonce uniqueness cannot be maintained and security risks are significant. However, MRAE schemes can be quite expensive. Two of the SoTA MRAE-secure schemes; Deoxys-II and AES-GCM-SIV

Impossible Differential Attack on SAND-128 [PDF]
Impossible differential attack is one of the major cryptanalytical methods for symmetric-key block ciphers. In this paper, we evaluate the security of SAND-128 against impossible differential attack.

Electromagnetic Side-Channel Resilience against Lightweight Cryptography [PDF]
Side-channel attacks are an unpredictable risk factor in cryptography. Therefore, observations of leakages through physical parameters, i.e., power and electromagnetic (EM) radiation, etc., of digital devices are essential to minimise vulnerabilities ...

Optimizing Key Recovery in Impossible Cryptanalysis and Its Automated Tool [PDF]
Impossible differential (ID) cryptanalysis and impossible boomerang (IB) cryptanalysis are two methods of impossible cryptanalysis against block ciphers. Since the seminal work introduced by Boura et al.

Impossible Differential Automation: Model Generation and New Techniques [PDF]
In this paper, we aim to enhance and automate advanced techniques for impossible differential attacks. To demonstrate these advancements, we present improved attacks on the LBlock and HIGHT block ciphers. More precisely, we (a) introduce a methodology to

Trail-Estimator: An Automated Verifier for Differential Trails in Block Ciphers [PDF]
Differential cryptanalysis is a powerful technique for attacking block ciphers, wherein the Markov cipher assumption and stochastic hypothesis are commonly employed to simplify the search and probability estimation of differential trails.

A Holistic Framework for Impossible Boomerang Attacks [PDF]
In 2011, Lu introduced the impossible boomerang attack at DCC. This powerful cryptanalysis technique combines the strengths of the impossible differential and boomerang attacks, thereby inheriting the advantages of both cryptographic techniques.

A generic algorithm for efficient key recovery in differential attacks – and its associated tool [PDF]
Differential cryptanalysis is an old and powerful attack against block ciphers. While different techniques have been introduced throughout the years to improve the complexity of this attack, the key recovery phase remains a tedious and error-prone ...
