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 Feistel network. Many block encryption algorithms are...
Generation of Round Key Using Random Number Generator approach and Use of unique round function for each round .Thus the existing Feistel structure has been modified to create a new block-cipher structure which incorporates effective key generation and round function approaches to provide effective data...
This paper focuses on how to build a secure tweakable block cipher from the Key-Alternating Feistel (KAF) structure, a dedicated Feistel structure with round functions of the form \\(F_i(k_i\\oplus x_i)\\), where \\(k_i\\) is the secret round key and \\(F_i\\) is a ...

The Feistel structure is a very commonly used structure to build block ciphers. Here, we present a 5-round quantum key-recovery attack on Feistel structures. As depicted in Figure 3, FiFi is the iith round function that absorbs the independent round key kiki. Suppose the state size is nn,...

In this paper, a low-energy lightweight block cipher named as GFLE is presented. The core cipher of GFLE uses a variant of the Generalized Feistel Structure (GFS) with 4-branch, which combines the Type-II GFS with the simplified Lai-Massey. The DRmax of GFLE has a one-round ...
