Forking Tweakable Even-Mansour Ciphers [PDF]
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.

Cryptanalysis of Forkciphers [PDF]
IACR Transactions on Symmetric Cryptology, 2020 The forkcipher framework was designed in 2018 by Andreeva et al. for authenticated encryption of short messages. Two dedicated ciphers were proposed in this framework: ForkAES based on the AES (and its tweakable variant Kiasu-BC), and ForkSkinny based on

1, 2, 3, Fork: Counter Mode Variants based on a Generalized Forkcipher [PDF]
IACR Transactions on Symmetric Cryptology, 2021 A multi-forkcipher (MFC) is a generalization of the forkcipher (FC) primitive introduced by Andreeva et al. at ASIACRYPT’19. An MFC is a tweakable cipher that computes s output blocks for a single input block, with s arbitrary but fixed.

Authenticity in the Presence of Leakage using a Forkcipher [PDF]
IACR Communications in CryptologyRobust message authentication codes (MACs) and authenticated encryption (AE) schemes that provide authenticity in the presence of side-channel leakage are essential primitives. These constructions often rely on primitives designed for strong leakage protection, among others including the use of strong-unpredictable (tweakable) block-ciphers.

Tweakable ForkCipher from Ideal Block Cipher [PDF]
IACR Communications in CryptologyIn ASIACRYPT 2019, Andreeva et al. introduced a new symmetric key primitive called the forkcipher, designed for lightweight applications handling short messages. A forkcipher is a keyed function with a public tweak, featuring fixed-length input and fixed-length (expanding) output.

On the Key-Commitment Properties of Forkcipher-based AEADs [PDF]
IACR Communications in CryptologyForkcipher-based AEADs have emerged as lightweight and efficient cryptographic modes, making them suitable for resource-constrained environments such as IoT devices and distributed decryption through MPC. These schemes, including prominent examples like Eevee (Jolteon, Espeon, and Umbreon), PAEF, RPAEF, and SAEF, leverage the properties of forkciphers ...

What the Fork: Implementation Aspects of a Forkcipher [PDF]
, 2019 Lightweight cryptography refers to cryptographic designs that are heavily optimized to minimize resources, such as computational complexity, latency, energy/power consumption, hardware area, code size, and RAM, or to be very efficient in a particular application scenario, where the “conventional” cryptography would not suffice.

FEDT: Forkcipher-based Leakage-resilient Beyond-birthday-secure AE [PDF]
IACR Communications in CryptologyThere has been a notable surge of research on leakage-resilient authenticated encryption (AE) schemes, in the bounded as well as the unbounded leakage model. The latter has garnered significant attention due to its detailed and practical orientation. Designers have commonly utilized (tweakable) block ciphers, exemplified by the TEDT scheme, achieving
