We show that a future adversary with access to a quantum computer, historic network traffic protected by WireGuard, and knowledge of a WireGuard user's long-term static public key can likely decrypt m...
Elastic-Tweak: A Framework for Short Tweak Tweakable Block Cipher
tweakable block cipher GIFT AES
2019/5/5
Tweakable block cipher (TBC), a stronger notion than standard block ciphers, has wide-scale applications in symmetric-key schemes. At a high level, it provides flexibility in design and (possibly) bet...
Related-Tweak Statistical Saturation Cryptanalysis and Its Application on QARMA
Related-Tweak Statistical Saturation KDIB Conditional Equivalence
2019/3/1
Statistical saturation attack takes advantage of a set of plaintext with some bits fixed while the others vary randomly, and then track the evolution of a non-uniform plaintext distribution through th...
MILP-Aided Related-Tweak/Key Impossible Differential Attack and Its applications to QARMA, Joltik-BC
Tweakable block cipher Impossible differential attack Related-Tweakey
2018/2/9
In this paper, we study the relation of single-key impossible differentials with the related-tweakey/key ones and propose an interesting algorithm that can efficiently derive longer related-tweakey/ke...
Clustering Related-Tweak Characteristics: Application to MANTIS-6
Truncated Differential Cryptanalysis TWEAKEY MANTIS
2017/11/28
The TWEAKEY/STK construction is an increasingly popular approach for designing tweakable block ciphers that notably uses a linear tweakey schedule. Several recent attacks have analyzed the implication...
A Tweak for a PRF Mode of a Compression Function and Its Applications
compression function MAC pseudorandom function
2016/6/22
We discuss a tweak for the domain extension called Merkle-Damg錼d with Permutation (MDP), which was presented at ASIACRYPT 2007. We first show that MDP may produce multiple independent pseudorandom fun...
Trick or Tweak: On the (In)security of OTR’s Tweaks
cryptanalysis authenticated encryption CAESAR competition
2016/3/4
Tweakable blockcipher (TBC) is a powerful tool to design authenticated encryption
schemes as illustrated by Minematsu’s OTR construction. It considers an additional input, called
tweak, to a standar...
Beyond-Birthday-Bound Security for Tweakable Even-Mansour Ciphers with Linear Tweak and Key Mixing
tweakable block cipher iterated Even-Mansour cipher key-alternating cipher
2015/12/23
The iterated Even-Mansour construction defines a block cipher from a tuple of public $n$-bit permutations $(P_1,\ldots,P_r)$ by alternatively xoring some $n$-bit round key $k_i$, $i=0,\ldots,r$, and a...
Tweak-Length Extension for Tweakable Blockciphers
Tweakable blockcipher Tweak extension Mode of operation
2015/12/23
Tweakable blockcipher (TBC) is an extension of standard
blockcipher introduced by Liskov, Rivest and Wagner in 2002. TBC is a
versatile building block for efficient symmetric-key cryptographic funct...
Counter-in-Tweak: Authenticated Encryption Modes for Tweakable Block Ciphers
authenticated encryption tweakable block cipher nonce-misuse resistance
2015/12/21
We propose the Synthetic Counter-in-Tweak (SCT) mode,
which turns a tweakable block cipher into a nonce-based authenticated
encryption scheme (with associated data). The SCT mode combines in
a SIV-...
