A General Analysis of the Security of Elastic Block Ciphers [PDF]
, 2005 We analyze the security of elastic block ciphers in general to show that an attack on an elastic version of block cipher implies a polynomial time related attack on the fixed-length version of the block cipher.

On Elastic Block Ciphers and Their Differential and Linear Cryptanalyses [PDF]
, 2005 Motivated by applications such as databases with nonuniform field lengths, we introduce the concept of an elastic block cipher, a new approach to variable length block ciphers which incorporates fixed sized cipher components into a new network structure.

Quantitative Evaluation of Chaotic CBC Mode of Operation [PDF]
, 2016 The cipher block chaining (CBC) block cipher mode of operation presents a very popular way of encrypting which is used in various applications. In previous research work, we have mathematically proven that, under some conditions, this mode of operation ...

Elastic Block Ciphers: Method, Security and Instantiations [PDF]
, 2009 We introduce the concept of an elastic block cipher which refers to stretching the supported block size of a block cipher to any length up to twice the original block size while incurring a computational workload that is proportional to the block size ...

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 ...

Proceedings of the 2nd ACM symposium on Information, computer and communications security, 2007 We introduce the concept of an elastic block cipher, which refers to stretching the supported block size of a block cipher to any length up to twice the original block size while incurring a computational workload that is proportional to the block size. We define a method for converting any existing block cipher into an elastic block cipher and mention

Parallel Implementation of PIPO and Its Application for Format Preserving Encryption
IEEE Access, 2022 The PIPO block cipher, a domestic lightweight block cipher, was announced at ICISC’20. In particular, the bitslicing technique is implemented in the S-Layer for the PIPO block cipher.

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

Counter Mode of the Shannon Block Cipher Based on MPF Defined over a Non-Commuting Group
Mathematics, 2022 In this paper, we present a counter mode of a Shannon block cipher based on the matrix power function. We make use of the matrix power function to define a single round symmetric cipher.
