In this paper previous algorithm based on DNA cryptography is enhanced in terms of its security parameter by incurring feistel inspired structure in it. This adds some sort of confusion and diffusion, which makes it complex enough that it restricts the adversary to perform any kind of brute ...
Cryptography series: feistel cipher Introduction Feistel cipher is also called Luby-Rackoff block cipher, which is used to construct a symmetric structure of block encryption algorithm. It was invented by the German cryptographer Horst Feistel while working at IBM. Feistel cipher is also called Feiste...
It can be applied to the Feistel structure effectively. Then, we introduce CLEFIA, a representative cipher of Feistel families, and present a 11-round attack on it with differential-linear cryptanalysis. The data complexity is 2116.52 ,and we recover 96-bit keys in total. After that, the ...
Symmetric ciphers are an essential branch of cryptography, pivotal in ensuring information security. Dominant symmetric ciphers are currently built upon various frameworks, including Substitution–Permutation-Network, Lai–Massey scheme, and the Feistel structure. The Feistel structure, initially introduced in...
