Bit‐level evaluation of piccolo block cipher by satisfiability problem solver

IET Information Security, Volume 17, Issue 4, Page 616-625, July 2023., 2023
The authors conducted bit‐level evaluations of the Piccolo block cipher against differential, integral, and impossible differential attacks using SAT‐based approaches. Authors’ work successfully identified the optimal differential distinguisher against differential and related‐key differential attacks.

Agonistic behavior of captive saltwater crocodile, crocodylus porosus in Kota Tinggi, Johor [PDF]

, 2021
Agonistic behavior in Crocodylus porosus is well known in the wild, but the available data regarding this behavior among the captive individuals especially in a farm setting is rather limited. Studying the aggressive behavior of C.

Design and cryptanalysis of a new iterative structure

IET Information Security, Volume 17, Issue 3, Page 335-346, May 2023., 2023
We propose a new iterative structure called the L‐Feistel structure, which has a similar encryption with decryption. The L‐Feistel structure not only provides a unified view of the Feistel structure and the Lai–Massey structure but also enlarges the choices of structures for block cipher designs.

Dynamic Selection of Symmetric Key Cryptographic Algorithms for Securing Data Based on Various Parameters [PDF]

, 2014
Most of the information is in the form of electronic data. A lot of electronic data exchanged takes place through computer applications. Therefore information exchange through these applications needs to be secure.

On Generalized Feistel Networks [PDF]

, 2010
We prove beyond-birthday-bound security for most of the well-known types of generalized Feistel networks: (1) unbalanced Feistel networks, where the n-bit to m-bit round functions may have n ≠ m; (2) alternating Feistel networks, where the round functions alternate between contracting and expanding; (3) type-1, type-2, and type-3 Feistel networks ...

Developments in generalised Feistel networks

Electronics Letters, 1999
Nyberg (1996) obtained an upper bound on the maximum average of differential probability for a generalised Feistel network. A counter-example to this result is given.

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 ...
