Grover on Korean Block Ciphers
Applied Sciences, 2020 The Grover search algorithm reduces the security level of symmetric key cryptography with n-bit security level to O(2n/2). In order to evaluate the Grover search algorithm, the target block cipher should be efficiently implemented in quantum circuits ...

Survey and Benchmark of Block Ciphers for Wireless Sensor Networks [PDF]
ACM Transactions on Sensor Networks, 2006 Cryptographic algorithms play an important role in the security architecture of wireless sensor networks (WSNs). Choosing the most storage- and energy-efficient block cipher is essential, due to the facts that these networks are meant to operate without ...

Probability distributions of correlation and differentials in block ciphers
Journal of Mathematical Cryptology, 2007 We study the probability distributions of difference propagation probabilities and input-output correlations for functions and block ciphers of given dimensions, for several of them for the first time.

Optimally Secure Tweakable Block Ciphers with a Large Tweak from n-bit Block Ciphers
IACR Transactions on Symmetric Cryptology, 2023 We consider the design of a tweakable block cipher from a block cipher whose inputs and outputs are of size n bits. The main goal is to achieve 2n security with a large tweak (i.e., more than n bits). Previously, Mennink at FSE’15 and Wang et al.

Probabilistic Block Cipher [PDF]
Annals of Computer Science and Information Systems, 2018 This paper is devoted to the description of a new block cipher that will be applicable in the post-quantum era and will not need a lot of resources. The main advantages: probabilistic encryption, the cipher block chaining mode, the ability to transfer to distributed systems. All this combined with the use of PRNG, working on the Cremona transformations,

RAFA: Redundancies-assisted Algebraic Fault Analysis and its implementation on SPN block ciphers
Transactions on Cryptographic Hardware and Embedded Systems, 2023 Algebraic Fault Analysis (AFA) is a cryptanalysis for block ciphers proposed by Courtois et al., which incorporates algebraic cryptanalysis to overcome the complexity of manual analysis within the context of Differential Fault Analysis (DFA).
