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

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.

Tweakable ForkCipher from Ideal Block Cipher [PDF]

IACR Communications in Cryptology
In 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-

Authenticity in the Presence of Leakage using a Forkcipher [PDF]

IACR Communications in Cryptology
Robust message authentication codes (MACs) and authenticated encryption (AE) schemes that provide authenticity in the presence of side-channel leakage are essential primitives.

On the Key-Commitment Properties of Forkcipher-based AEADs [PDF]

IACR Communications in Cryptology
Forkcipher-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.

FEDT: Forkcipher-based Leakage-resilient Beyond-birthday-secure AE [PDF]

IACR Communications in Cryptology
There has been a notable surge of research on leakage-resilient authenticated encryption (AE) schemes, in the bounded as well as the unbounded leakage model.

1, 2, 3, Fork: Counter Mode Variants based on a Generalized Forkcipher

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.

Forkcipher: a New Primitive for Authenticated Encryption of Very Short Messages [PDF]

IACR Cryptology ePrint Archive, 2019
Highly efficient encryption and authentication of short messages is an essential requirement for enabling security in constrained scenarios such as the CAN FD in automotive systems (max. message size 64 bytes), massive IoT, critical communication domains

Multiple Impossible Differential Attacks for ForkAES

Security and Communication Networks, 2022
To yield a highly efficient authentication encryption design for very short messages, the tweakable forkcipher is proposed, which is a tweakable block cipher that uses forking construction to produce two output blocks.
