On Compression of Data Encrypted with Block Ciphers [PDF]
2009 Data Compression Conference, 2009 This paper investigates compression of data encrypted with block ciphers, such as the Advanced Encryption Standard (AES). It is shown that such data can be feasibly compressed without knowledge of the secret key. Block ciphers operating in various chaining modes are considered and it is shown how compression can be achieved without compromising ...

New Methodology of Block Cipher Analysis using Chaos Game [PDF]
ITB Journal of Information and Communication Technology, 2011 Block cipher analysis covers randomness analysis and cryptanalysis. This paper proposes a new method potentially used for randomness analysis and cryptanalysis. The method uses true random sequence concept as a reference for measuring randomness level of

On some block ciphers and imprimitive groups [PDF]
Applicable Algebra in Engineering, Communication and Computing, 2008 The group generated by the round functions of a block ciphers is a widely investigated problem. We identify a large class of block ciphers for which such group is easily guaranteed to be primitive. Our class includes the AES and the SERPENT.

Importance of S-Blocks in Modern Block Ciphers [PDF]
International Journal of Computer Network and Information Security, 2012 There is a new approach to determine the degree of cryptographic S-boxes suitability. This approach is based on estimating the number of transformation cycles required for a cipher to achieve differential and linear nature of the state typical for random substitution of the appropriate degree.

Optimally Secure Tweakable Block Ciphers with a Large Tweak from n-bit Block Ciphers
IACR Transactions on Symmetric Cryptology, 2023 We consider the design of a tweakable block cipher from a block cipher whose inputs and outputs are of size n bits. The main goal is to achieve 2n security with a large tweak (i.e., more than n bits). Previously, Mennink at FSE’15 and Wang et al.

BipBip: A Low-Latency Tweakable Block Cipher with Small Dimensions
IACR Trans. Cryptogr. Hardw. Embed. Syst., 2022 Recently, a memory safety concept called Cryptographic Capability Computing (C3) has been proposed. C3 is the first memory safety mechanism that works without requiring extra storage for metadata and hence, has the potential to significantly enhance the ...
