Summary of Topological Study of Chaotic CBC Mode of Operation [PDF]
, 2016 International audience—In cryptography, block ciphers are the most fundamental elements in many symmetric-key encryp-tion systems. The Cipher Block Chaining, denoted CBC, presents one of the most famous mode of operation that uses a block cipher to ...

CRAFT: Lightweight Tweakable Block Cipher with Efficient Protection Against DFA Attacks
IACR Cryptology ePrint Archive, 2019 Traditionally, countermeasures against physical attacks are integrated into the implementation of cryptographic primitives after the algorithms have been designed for achieving a certain level of cryptanalytic security.

IACR Cryptology ePrint Archive, 2004 We introduce a new concept of elastic block ciphers, symmetric-key encryption algorithms that for a variable size input do not expand the plaintext, (i.e., do not require plaintext padding), while maintaining the diffusion property of traditional block ciphers and adjusting their computational load proportionally to the size increase.

Grover on Korean Block Ciphers [PDF]
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. Recently, many research works evaluated required quantum resources of AES block ciphers by optimizing ...

Survey and Benchmark of Block Ciphers for Wireless Sensor Networks [PDF]
, 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 ...

, 2002 In this paper, we propose a new symmetric key block cipher SC2000 with 128-bit block length and 128-,192-,256- bit key lengths. The block cipher is constructed by piling two layers: one is a Feistel structure layer and the other is an SPN structure layer. Each operation used in two layers is S-box or logical operation, which has been well studied about

, 2011 We present a new block cipher LED. While dedicated to compact hardware implementation, and offering the smallest silicon footprint among comparable block ciphers, the cipher has been designed to simultaneously tackle three additional goals. First, we explore the role of an ultra-light (in fact non-existent) key schedule.

Enhancing Embedded Data Security By Turns Cipher Block Chaining Mode Into Stream Cipher [PDF]
Engineering and Technology Journal, 2009 In this paper, a secure data hiding method is introduced. It increases the security of embedded data through combining between the steganography and cryptography. First, the secrete message is divided into blocks with same size according to length of key
