Lightweight Leakage-Resilient PRNG from TBCs using Superposition [PDF]
In this paper, we propose a leakage-resilient pseudo-random number generator (PRNG) design that leverages the rekeying techniques of the PSV-Enc encryption scheme and the superposition property of the Superposition-Tweak-Key (STK) framework.

Impossible Boomerang Attacks Revisited: Applications to Deoxys-BC, Joltik-BC and SKINNY [PDF]
The impossible boomerang (IB) attack was first introduced by Lu in his doctoral thesis and subsequently published at DCC in 2011. The IB attack is a variant of the impossible differential (ID) attack by incorporating the idea of the boomerang attack.

Tortoise: An Authenticated Encryption Scheme
Given the open nature of the Internet, there is a need for authentication schemes to address inherent trust issues. We present Tortoise, an experimental nonce-based authenticated encryption scheme modeled on the Synthetic Counter-in-Tweak.

Exploiting Redundant Designs with Side-Channel Attacks [PDF]
Sidekanalsangrep (SKA) er en bred angrepsklasse der en angriper utnytter en uforventet informasjonslekkasje til å omgå et sikkerhetstiltak. Hvorfor skulle man orke å knekke en kryptert telefonsamtale når man kan stå i naborommet og lytte gjennom veggen ...

A Long Tweak Goes a Long Way: High Multi-user Security Authenticated Encryption from Tweakable Block Ciphers [PDF]
We analyze the multi-user (mu) security of a family of nonce-based authentication encryption (nAE) schemes based on a tweakable block cipher (TBC). The starting point of our work is an analysis of the mu security of the SCT-II mode which underlies the ...

Quantum impossible differential attack. Applications to CLEFIA, AES and SKINNY [PDF]
, 2019 International audienceThe general context Cryptography is a computer discipline that aims to protect messages through encryption systems. In symmetric cryptography, a secret parameter, called a key, is used both to encrypt and to decrypt messages.

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.
