In this context, we propose a new ultralightweight RFID mutual authentication protocol based on the Feistel cipher structure. This structure is based on substitutions and random permutations which create confusion and diffusion in the transmitted messages. The main contribution of this work is the ...
Feistel Cipher structure is the reference structure for designing block- ciphers. In this paper we have proposed three variants to feistel structure to enhance the security of the data. The three constructive variants includes new design structure (The features of the derived structure includes 256 ...

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...
Block cipherKey-alternating cipherFeistel cipherCouplingProvable securityWe study the security of key-alternating Feistelciphers, a class of key-alternating ciphers with a Feistel structure. Alternatively, this may be viewed as the study of Feistel ciphers where the......

Hence, using Grover's algorithm to perform a brute-force search on all the subkeys, kiki, of an rr-round Feistel cipher will require 20.25nr20.25nr quantum queries. We combine Grover's and Simon's algorithms to generate a series of quantum key-recovery attacks on different rounds of ...

We call this the FL-structure (Feistel-like structure). If the round function of the FL structure is chosen in the same way as the round function of the Feistel-based block cipher, then the new construction, when using more than two rounds, inherits many of the properties of the ...
