Practical Key-Recovery Attack on MANTIS5
IACR Transactions on Symmetric Cryptology, 2017 MANTIS is a lightweight tweakable block cipher published at CRYPTO 2016. In addition to the full 14-round version, MANTIS7, the designers also propose an aggressive 10-round version, MANTIS5.

Spook: Sponge-Based Leakage-Resistant Authenticated Encryption with a Masked Tweakable Block Cipher
IACR Transactions on Symmetric Cryptology, 2020 This paper defines Spook: a sponge-based authenticated encryption with associated data algorithm. It is primarily designed to provide security against side-channel attacks at a low energy cost. For this purpose, Spook is mixing a leakageresistant mode of

Mini-ciphers: a reliable testbed for cryptanalysis? [PDF]
, 2009 This paper reports on higher-order square analysis of the AES cipher. We present experimental results of attack simulations on mini-AES versions with word sizes of 3, 4, 5, 6 and 7 bits and describe the propagation of higher-order Lambda-sets inside some

Stream ciphers: A Practical Solution for Efficient Homomorphic-Ciphertext Compression [PDF]
, 2015 International audienceIn typical applications of homomorphic encryption, the first step consists for Alice to encrypt some plaintext m under Bob’s public key pk and to send the ciphertext c = HEpk(m) to some third-party evaluator Charlie.

Cryptanalysis of PMACx, PMAC2x, and SIVx
IACR Transactions on Symmetric Cryptology, 2017 At CT-RSA 2017, List and Nandi proposed two variable input length pseudorandom functions (VI-PRFs) called PMACx and PMAC2x, and a deterministic authenticated encryption scheme called SIVx.

ESTATE: A Lightweight and Low Energy Authenticated Encryption Mode
IACR Transactions on Symmetric Cryptology, 2020 NIST has recently initiated a standardization project for efficient lightweight authenticated encryption schemes. SUNDAE, a candidate in this project, achieves optimal state size which results in low circuit overhead on top of the underlying block cipher.

MMM: Authenticated Encryption with Minimum Secret State for Masking
Transactions on Cryptographic Hardware and Embedded Systems, 2023 We propose a new authenticated encryption (AE) mode MMM that achieves the minimum memory size with masking. Minimizing the secret state is the crucial challenge in the low-memory AE suitable for masking.

Counter-in-Tweak: Authenticated Encryption Modes for Tweakable Block Ciphers [PDF]
, 2016 We propose the Synthetic Counter-in-Tweak $$\mathsf {SCT}$$ mode, which turns a tweakable block cipher into a nonce-based authenticated encryption scheme with associated data. The $$\mathsf {SCT}$$ mode combines in a SIV-like manner a Wegman-Carter MAC inspired from $$\mathsf {PMAC}$$ for the authentication part and a new counter-like mode for the ...
