Cogliati et al. introduced the tweakable Even-Mansour cipher constructed from a single permutation and an almost-XOR-universal (AXU) family of hash functions with tweak and key schedule. Most of previ...
In the ordinary security model for signature schemes, we consider an adversary that may forge a signature on a new message using only his knowledge of other valid message and signature pairs. To tak...
In a basic related-key attack against a block cipher, the adversary has access to encryptions under keys that differ from the target key by bit-flips. In this short note we show that for a quantum adv...
Message Authentication Code (MAC) is one of most basic primitives in cryptography. After Biham (EUROCRYPT 1993) and Knudsen (AUSCRYPT 1992) proposed related-key attacks (RKAs), RKAs have damaged MAC's...
We present attacks on full Hummingbird-2 which are able to recover the 128-bit secret keys of two black box cipher instances that have a certain type of low-weight XOR difference in their keys. We cal...
The hardware-attractive block cipher family KTANTAN was studied by Bogdanov and Rechberger who identified flaws in the key schedule and gave a meet-in-the-middle attack. We revisit their result before...
We show how to leverage the RKA (Related-Key Attack) security of blockciphers to provide RKA security for a suite of high-level primitives. This motivates a more general theoretical question, namely, ...
Bellare and Kohno introduced a formal framework for the study of related-key attacks against blockciphers. They established sufficient conditions (output-unpredictability and collision-resistance) on ...
In a related-key attack (RKA) an adversary attempts to break a cryptographic primitive by invoking the primitive with several secret keys which satisfy some known, or even chosen, relation. We initiat...
Differential and linear attacks are the most widely used cryptanalytic tools to evaluate the security of symmetric-key cryptography. Since the introduction of differential and linear attacks in the ...
