Sequential Attack with Intensity Modulation on the Differential-Phase-Shift Quantum Key Distribution Protocol [PDF]
, 2006 In this paper, we discuss the security of the differential-phase-shift quantum key distribution (DPSQKD) protocol by introducing an improved version of the so-called sequential attack, which was originally discussed by Waks et al. Our attack differs from

Security Analysis of SKINNY under Related-Tweakey Settings
IACR Transactions on Symmetric Cryptology, 2017 In CRYPTO’16, a new family of tweakable lightweight block ciphers - SKINNY was introduced. Denoting the variants of SKINNY as SKINNY-n-t, where n represents the block size and t represents the tweakey length, the design specifies t ∈ {n, 2n, 3n}. In this

Related-Key Impossible Differential Attacks on Crypton
International Journal of Intelligent Computing Research, 2011 Crypton is a 12-round block cipher proposed as an AES candidate and Crtpton v1.0 is the revised version. In this paper, we present two related-key impossible differential attacks to reduced-round Crypton and Crypton v1.0. By carefully choosing the relations of keys, constructing some 6round related-key differential trials and using some observations on

Cryptanalysis of Reduced-Round SPECK
IEEE Access, 2019 SPECK, a family of lightweight block ciphers proposed by the National Security Agency (NSA), is widely used under resource constrained environment. There are many cryptanalytic results on SPECK concentrated on differential and linear attacks.

Improved Impossible Differential Attacks on Large-Block Rijndael [PDF]
, 2013 In this paper, we present more powerful 6-round impossible differentials for large-block Rijndael-224 and Rijndael-256 than the ones used by Zhang et al. in ISC 2008. Using those, we can improve the previous impossible differential cryptanalysis of both 9-round Rijndael-224 and Rijndael-256.

Cryptanalysis of LowMC instances using single plaintext/ciphertext pair
IACR Transactions on Symmetric Cryptology, 2020 Arguably one of the main applications of the LowMC family ciphers is in the post-quantum signature scheme PICNIC. Although LowMC family ciphers have been studied from a cryptanalytic point of view before, none of these studies were directly concerned ...
