Quantum Chosen-Ciphertext Attacks Against Feistel Ciphers

2019
Seminal results by Luby and Rackoff show that the 3-round Feistel cipher is secure against chosen-plaintext attacks (CPAs), and the 4-round version is secure against chosen-ciphertext attacks (CCAs). However, the security significantly changes when we consider attacks in the quantum setting, where the adversary can make superposition queries.

A chaos-based block cipher with Feistel structure

2014 IEEE 13th International Conference on Cognitive Informatics and Cognitive Computing, 2014
In this paper, based on chaotic systems and balanced Feistel network structure, a symmetric block cipher with 256-bit secret key is proposed. The cipher operates on 64-bit plaintext blocks through 16 rounds computing. Within the kernel component of the cipher, i.e., round function F, a hyperchaotic system with four-wing attractors is used to improve ...

The Security of Feistel Ciphers with Six Rounds or Less

Journal of Cryptology, 2002
\textit{M. Luby} and \textit{C. Rackoff} [SIAM J. Comput. 17, 373-386 (1988; Zbl 0644.94018)] showed a method for constructing pseudorandom permutations from pseudorandom functions by using three or four rounds of Feistel networks. The security of their construction as well as others suggested later is measured in terms of the complexity of ...
