Cryptanalysis of Rocca and Feasibility of Its Security Claim
IACR Transactions on Symmetric Cryptology, 2022 Rocca is an authenticated encryption with associated data scheme for beyond 5G/6G systems. It was proposed at FSE 2022/ToSC 2021(2), and the designers make a security claim of achieving 256-bit security against key-recovery and distinguishing attacks ...

Speed Optimizations in Bitcoin Key Recovery Attacks [PDF]
Tatra Mountains Mathematical Publications, 2016 Abstract In this paper, we study and give the first detailed benchmarks on existing implementations of the secp256k1 elliptic curve used by at least hundreds of thousands of users in Bitcoin and other cryptocurrencies. Our implementation improves the state of the art by a factor of 2.5 with a focus on the cases, where side channel ...

Resistance of Ascon Family Against Conditional Cube Attacks in Nonce-Misuse Setting
IEEE Access, 2023 Ascon family is one of the finalists of the National Institute of Standards and Technology (NIST) lightweight cryptography standardization process. The family includes three Authenticated Encryption with Associated Data (AEAD) schemes: Ascon-128 (primary)

Key-Recovery Attacks on Full Kravatte
IACR Transactions on Symmetric Cryptology, 2018 This paper presents a cryptanalysis of full Kravatte, an instantiation of the Farfalle construction of a pseudorandom function (PRF) with variable input and output length. This new construction, proposed by Bertoni et al., introduces an efficiently parallelizable and extremely versatile building block for the design of symmetric mechanisms, e.g ...

Fault Template Attack Based on Fault Probability
IEEE Access, 2023 Template attack uses leaked information from various side channels and may break out the countermeasures embedded in the algorithm, which is considered a powerful side-channel attack method.

A Comprehensive Study of the Key Enumeration Problem
Entropy, 2019 In this paper, we will study the key enumeration problem, which is connected to the key recovery problem posed in the cold boot attack setting. In this setting, an attacker with physical access to a computer may obtain noisy data of a cryptographic ...

Meet-in-the-Middle Attacks on Classes of Contracting and Expanding Feistel Constructions
IACR Transactions on Symmetric Cryptology, 2017 We show generic attacks on unbalanced Feistel ciphers based on the meet-in-the-middle technique. We analyze two general classes of unbalanced Feistel structures, namely contracting Feistels and expanding Feistels.

A Key-Recovery Attack on SOBER-128
, 2007 In this talk we consider linear approximations of layered cipher constructions with secret key-dependent constants that are inserted between layers, and where the layers have strong interdependency. Then clearly, averaging over the constant would clearly be wrong as it will break the interdependencies, and the Piling Up-lemma cannot be used.

The Role of Hematopoietic Cell Transplantation in Ataxia‐Telangiectasia
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Ataxia‐telangiectasia (A‐T) is a DNA repair disorder characterized by neurodegeneration, immunodeficiency, and cancer predisposition. Hematopoietic cell transplantation (HCT) is an established therapy in related disorders such as Fanconi anemia (FA) and Nijmegen breakage syndrome (NBS), but its role in A‐T is unclear.

Security Analysis of Reusing Vinegar Values in UOV Signature Scheme
IEEE AccessMultivariate quadratic equation-based cryptographic algorithms are one of the promising post-quantum alternatives to current public-key cryptographic algorithms based on the discrete logarithm problem and the integer factorization problem. In this paper,
