Algebraic Properties of the Block Cipher DESL
Symmetry, 2019 The Data Encryption Standard Lightweight extension (DESL) is a lightweight block cipher which is very similar to DES, but unlike DES uses only a single S-box.

Several DES replacement block ciphers have been published. In this paper a report will be given on the development of a package for analysis and comparison of block ciphers. Experimental results are presented on applying this package to DES, FEAL-N, and Madryga ciphers.

Linear Frameworks for Block Ciphers
Designs, Codes and Cryptography, 2001In the paper linear components in (block) cipher structures are investigated, especially with respect to their role in providing resistance against differential and linear cryptanalysis. The cipher structures studied are similar to the classical Substitution-Permutation networks, however instead of permutations more general linear transformations are ...

Threshold cryptosystems use algebraic properties such as homomorphisms in order to allow several parties to jointly evaluate a cryptographic primitive. Several cryptographic primitives, however, avoid -by definition- the use of algebraic properties, or otherwise their security is compromised; this is the case, for instance, of block ciphers, pseudo ...

In this paper we present a new 96-bit block cipher called BKSQ. The cipher can be implemented efficiently on a wide range of processors (including smartcards) and in hardware.

Algebraic Differential Fault Analysis on SIMON Block Cipher
IEEE transactions on computers, 2019Algebraic differential fault attack (ADFA) is an attack in which an attacker combines a differential fault attack and an algebraic technique to break a targeted cipher.

This paper proposes a nested (hierarchical) SPN structure and the symmetric block cipher "Hierocrypt". In the nested SPN structure, lower-level SPN structures are recursively embedded into S-box positions in SPN of the higher level. This structure recursively assures the lower bound of active S-box number, and high security level is efficiently ...

HEVC Selective Encryption Using RC6 Block Cipher Technique
IEEE transactions on multimedia, 2018The high efficiency video coding (HEVC) partial encryption (PE) technique depends on encrypting the highly sensitive data on the video bit stream. The HEVC PE technique should keep the video format compliance, should be of the same bit rate, and ensure ...

This paper describes the MESH block ciphers, whose designs are based on the same group operations as the IDEA cipher, but with a number of novel features: flexible block sizes in steps of 32 bits (the block size of IDEA is fixed at 64 bits); larger MA-boxes; distinct key-mixing layers for odd and even rounds; and new key schedule algorithms that ...
