On the Security of Sponge-type Authenticated Encryption Modes
IACR Transactions on Symmetric Cryptology, 2020 The sponge duplex is a popular mode of operation for constructing authenticated encryption schemes. In fact, one can assess the popularity of this mode from the fact that around 25 out of the 56 round 1 submissions to the ongoing NIST lightweight ...

New Differential‐Based Distinguishers for Ascon via Constraint Programming
IET Information Security, Volume 2024, Issue 1, 2024.As the winner of the NIST lightweight cryptography project, Ascon has undergone extensive self‐evaluation and third‐party cryptanalysis. In this paper, we use constraint programming (CP) as a tool to analyze the Ascon permutation and propose several differential‐based distinguishers.

On the Key-Commitment Properties of Forkcipher-based AEADs
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 ...

CCA Security with Short AEAD Tags
IACR Communications in CryptologyThe size of the authentication tag represents a significant overhead for applications that are limited by bandwidth or memory. Hence, some authenticated encryption designs have a smaller tag than the required privacy level, which was also suggested by the NIST lightweight cryptography standardization project.

Improved Conditional Cube Attacks on Ascon AEADs in Nonce-Respecting Settings
IACR Transactions on Symmetric CryptologyThe best-known distinguisher on 7-round Ascon-128 and Ascon-128a AEAD uses a 60-dimensional cube where the nonce bits are set to be equal in the third and fourth rows of the Ascon state during initialization (Rohit et al. ToSC 2021/1).

Cryptanalysis of IAR-CTR and IAR-CFB and a fixing method
CybersecurityWe present practical attacks on IAR-CTR and IAR-CFB, AE modes proposed by Hwang and Gope to offer both privacy and authenticity in a single pass. Then we use the idea of iCOFB, which is originally defined with a tweakable random function, to fix the IAR ...
