A New Method for Format Preserving Encryption in High-Data Rate Communications
IEEE Access, 2020 In some encryption systems it is necessary to preserve the format and length of the encrypted data. This kind of encryption is called FPE (Format Preserving Encryption).

Cryptanalysis of an MPEG-Video Encryption Scheme Based on Secret Huffman Tables [PDF]
, 2007 This paper studies the security of a recently-proposed MPEG-video encryption scheme based on secret Huffman tables. Our cryptanalysis shows that: 1) the key space of the encryption scheme is not sufficiently large against divide-and-conquer (DAC) attack ...

A Novel Hybrid Elementary Cellular Automata and Its Application in a Stream Cipher
Applied SciencesThe elementary cellular automata (ECAs) under the chaotic rule possess long periodicity and are widely used in pseudo-random number generators. However, their period is limited, related to the rule and the number of cells.

On the Key-Uncertainty of Quantum Ciphers and the Computational Security of One-way Quantum Transmission [PDF]
, 2004 We consider the scenario where Alice wants to send a secret (classical) $n$-bit message to Bob using a classical key, and where only one-way transmission from Alice to Bob is possible.
