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...
An important step for realizing a chaotic cryptography, that is, mapping real numbers in continuum into integers in a finite set is researched. On the base of conventional Feistel-structure, a 128 bits key cipher block algorithm based on chaos is proposed. Confusion and diffusion are necessary ...

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...
41、049Abstract The structure of a block cipher is one of the most important factors in its security. A good'' structure is able to protect the block cipher, while a bad'' one may induce some secret information leak out. Based on the former study of Balanced Feistel Networks, we study ...
