A Security Analysis of IoT Encryption: Side-channel Cube Attack on Simeck32/64 [PDF]
, 2018 Simeck, a lightweight block cipher has been proposed to be one of the encryption that can be employed in the Internet of Things (IoT) applications. Therefore, this paper presents the security of the Simeck32/64 block cipher against side-channel cube ...

Boomerang Connectivity Table:A New Cryptanalysis Tool [PDF]
, 2018 A boomerang attack is a cryptanalysis framework that regards a block cipher $E$ as the composition of two sub-ciphers $E_1\circ E_0$ and builds a particular characteristic for $E$ with probability $p^2q^2$ by combining differential characteristics for ...

Forking Tweakable Even-Mansour Ciphers
IACR Transactions on Symmetric Cryptology, 2020 A forkcipher is a keyed, tweakable function mapping an n-bit input to a 2nbit output, which is equivalent to concatenating two outputs from two permutations.

Improved Rectangle Attacks on SKINNY and CRAFT
IACR Transactions on Symmetric Cryptology, 2021 The boomerang and rectangle attacks are adaptions of differential cryptanalysis that regard the target cipher E as a composition of two sub-ciphers, i.e., E = E1 ∘ E0, to construct a distinguisher for E with probability p2q2 by concatenating two short ...

Re-Keying Scheme Revisited: Security Model and Instantiations
Applied Sciences, 2019 The re-keying scheme is a variant of the symmetric encryption scheme where a sender (respectively, receiver) encrypts (respectively, decrypts) plaintext with a temporal session key derived from a master secret key and publicly-shared randomness.

Improved Meet-in-the-Middle Preimage Attacks against AES Hashing Modes
IACR Transactions on Symmetric Cryptology, 2020 Hashing modes are ways to convert a block cipher into a hash function, and those with AES as the underlying block cipher are referred to as AES hashing modes.

Compact Hardware Implementations of ChaCha, BLAKE, Threefish, and Skein on FPGA [PDF]
, 2014 The cryptographic hash functions BLAKE and Skein are built from the ChaCha stream cipher and the tweakable Threefish block cipher, respectively. Interestingly enough, they are based on the same arithmetic operations, and the same design philosophy allows
