Proposal of New Block Cipher Algorithm [PDF]
Engineering and Technology Journal, 2010 Speed and complexity are two important properties in the block cipher.The block length of the block cipher controls these two aspects. The speedlimitation enforces the designer to build block cipher system as hardwareprototype.

Journal of Cryptology, 2002 A common trend in applications of block ciphers over the past decades has been to employ block ciphers as one piece of a “mode of operation”—possibly, a way to make a secure symmetric-key cryptosystem, but more generally, any cryptographic application.

Matrix Power Function Based Block Cipher Operating in CBC Mode
Mathematics, 2022 In our previous study, we proposed a perfectly secure Shannon cipher based on the so-called matrix power function. There we also introduced a concept of single round symmetric encryption, i.e., we used the matrix power function together with some rather ...

Efficient Implementation of PRESENT and GIFT on Quantum Computers
Applied Sciences, 2021 Grover search algorithm is the most representative quantum attack method that threatens the security of symmetric key cryptography. If the Grover search algorithm is applied to symmetric key cryptography, the security level of target symmetric key ...

Short Non-Malleable Codes from Related-Key Secure Block Ciphers, Revisited
IACR Transactions on Symmetric Cryptology, 2022 We construct non-malleable codes in the split-state model with codeword length m + 3λ or m + 5λ, where m is the message size and λ is the security parameter, depending on how conservative one is. Our scheme is very simple and involves a single call to a

SLIM: A Lightweight Block Cipher for Internet of Health Things
IEEE Access, 2020 Nowadays, there is a strong demand for increasing the protection of resource-constrained devices such as Radio frequency identification (RFID) systems. Current cryptographic algorithms are sufficient for high-resource desktop computers.

IACR Cryptology ePrint Archive, 2021 We introduce SPEEDY, a family of ultra low-latency block ciphers. We mix engineering expertise into each step of the cipher’s design process in order to create a secure encryption primitive with an extremely low latency in CMOS hardware.

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,

Parallel Implementations of ARIA on ARM Processors and Graphics Processing Unit
Applied Sciences, 2022 The ARIA block cipher algorithm is Korean standard, IETF standard (RFC 5794), and part of the TLS/SSL protocol. In this paper, we present the parallel implementation of ARIA block cipher on ARMv8 processors and GPU.

Designing pair of nonlinear components of a block cipher over quaternion integers
AIMS Mathematics, 2023 In the field of cryptography, block ciphers are widely used to provide confidentiality and integrity of data. One of the key components of a block cipher is its nonlinear substitution function.
