Feistal-type block cipher
WebCompared with other existing lightweight block ciphers, the ALLPC cipher can achieve compact hardware and low-cost software (e.g., low memory) while having low execution … WebTweakable block cipher (TBC) of 64-bit block size, such as SKINNY, is another promising way to prevent the birthday attacks of O(232) complexity. It still requires a change of outer modes (though BBB secure modes for TBCs are typically simpler than those for block ciphers) and hence, it generally does not realize a direct replacement of AES.

WebCamellia is a Feistel-type block cipher jointly developed by NTT (Nippon Telegraph and Telephone Corp.) and Mitsubishi Electric [3]. As with AES, Camellia supports 128-, 192-, and 256-bit keys. An advantage of the Feistel cipher is that the same datapath can be used for encryption and decryption. Fig. 3 shows our Camellia WebEncryption Process The input block to each round is divided into two halves that can be denoted as L and R for the left half and the right... In each round, the right half of the …
WebThe encryption key for the ideal block cipher is the codebook itself, meaning the table that shows the relationship between the input blocks and the output blocks. Figure 1 depicts … In cryptography, a Feistel cipher (also known as Luby–Rackoff block cipher) is a symmetric structure used in the construction of block ciphers, named after the German-born physicist and cryptographer Horst Feistel, who did pioneering research while working for IBM; it is also commonly known as a Feistel … See more Many modern symmetric block ciphers are based on Feistel networks. Feistel networks were first seen commercially in IBM's Lucifer cipher, designed by Horst Feistel and Don Coppersmith in 1973. Feistel networks … See more A Feistel network uses a round function, a function which takes two inputs – a data block and a subkey – and returns one output of the same size as the data block. In each round, the round function is run on half of the data to be encrypted, and its output is XORed … See more Let $${\displaystyle \mathrm {F} }$$ be the round function and let $${\displaystyle K_{0},K_{1},\ldots ,K_{n}}$$ be the sub-keys for the rounds $${\displaystyle 0,1,\ldots ,n}$$ See more • Cryptography • Stream cipher • Substitution–permutation network See more The structure and properties of Feistel ciphers have been extensively analyzed by cryptographers.

WebApr 12, 2024 · Lightweight block ciphers, a subfield of lightweight cryptography, include the substitution–permutation network (SPN) and Feistel-based networks. Feistel networks are further divided into two types: classical Feistel networks and generalized Feistel networks (GFN). While classical Feistel ciphers divide a message into two sub-blocks, GFN ... WebIn this paper, we propose related-key differential distinguishers based on the complementation property of Feistel ciphers. We show that with relaxed requirements on the complementation, i.e. the property does not have to hold for all keys and the complementation does not have to be on all bits, one can obtain a variety of …

We propose new generic key recovery attacks on Feistel-type block ciphers. The proposed attack is based on the all subkeys recovery approach presented in SAC 2012, which determines all subkeys instead of the master key.
