Breaking Tweakable Enciphering Schemes using Simon's Algorithm
TES Simon's algorithm Quantum period finding algorithm
<
2019/6/19
The threat of the possible advent of quantum computers has motivated the cryptographic community to search for quantum safe solutions. There have been some works in past few years showing the vulnerab...
ZOCB and ZOTR: Tweakable Blockcipher Modes for Authenticated Encryption with Full Absorption
ZOCB ZOTR Authenticated encryption Associated data
<
2019/6/3
We define ZOCB and ZOTR for nonce-based authenticated encryption with associated data, and analyze their provable security. These schemes use a tweakable blockcipher (TBC) as the underlying primitive,...
Reducing the Cost of Authenticity with Leakages: a CIML2-Secure AE Scheme with One Call to a Strongly Protected Tweakable Block Cipher
Leakage-resilience authenticated encryption leveled implementation

2019/5/9
This paper presents CONCRETE (Commit-Encrypt-Send-the-Key) a new Authenticated Encryption mode that offers CIML2 security, that is, ciphertext integrity in the presence of nonce misuse and side-channe...
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...
Lightweight Authenticated Encryption Mode of Operation for Tweakable Block Ciphers
Authenticated encryption beyond-birthday-bound security tweakable block- cipher
<
2019/4/3
Using a small block length is a common strategy in designing lightweight block cipher. So far, many 64-bit primitives have been proposed. However, if we use such a 64-bit primitive for an authenticate...

2019/3/1
The design and analysis of dedicated tweakable block ciphers is a quite recent and very active research field that provides an ongoing stream of new insights. For instance, results of Kranz, Leander, ...
CRAFT: Lightweight Tweakable Block Cipher with Efficient Protection Against DFA Attacks
CRAFT block cipher tweakable

2019/2/28
Traditionally, countermeasures against physical attacks are integrated into the implementation of cryptographic primitives after the algorithms have been designed for achieving a certain level of cryp...
ZCZ - Achieving n-bit SPRP Security with a Minimal Number of Tweakable-block-cipher Calls
n-bit security beyond birthday bound tweakable blockcipher
<
2018/11/19
Strong Pseudo-random Permutations (SPRPs) are important for various applications. In general, it is desirable to base an SPRP on a single-keyed primitive for minimizing the implementation costs. For c...
Wide Tweakable Block Ciphers Based on Substitution-Permutation Networks: Security Beyond the Birthday Bound

<
2018/5/28
Substitution-Permutation Networks (SPNs) refer to a family of constructions which build a wnwn-bit (tweakable) block cipher from nn-bit public permutations. Many widely deployed block ciphers are part...

2017/9/7
We present a length doubler, LDT, that turns an n-bit tweakable block cipher into an efficient and secure cipher that can encrypt any bit string of length [n..2n-1]. The LDT mode is simple, uses only ...
