Cryptography Using Quasi Group and Chaotic Maps [PDF]
, 2018 In this paper a symmetric key (stream cipher mode/block cipher mode) cryptosystem is proposed, involving chaotic maps and quasi group. The proposed cryptosystem destroys any existing patterns in the input, and also, it maximizes entropy.

SOSEMANUK: a fast software-oriented stream cipher [PDF]
New Stream Cipher Designs - The eSTREAM finalists (2008) 98-118, 2008 Sosemanuk is a new synchronous software-oriented stream cipher, corresponding to Profile 1 of the ECRYPT call for stream cipher primitives. Its key length is variable between 128 and 256 bits. It ac- commodates a 128-bit initial value. Any key length is claimed to achieve 128-bit security.

Molecular Oncology, EarlyView.Large multidimensional digital images of cancer tissue are becoming prolific, but many challenges exist to automatically extract relevant information from them using computational tools. We describe publicly available resources that have been developed jointly by expert and non‐expert computational biologists working together during a virtual hackathon

FPE scheme based on k-splits Feistel network
Tongxin xuebao, 2012 The construction features and discipline of Feistel network-based FPE(format-preserving encryption)schemes were analyzed.Considering on the problem that 2-splits Feistel networks-based FPE cipher’s block size was in narrow range,a type-2 Feistel network ...

A note on some algebraic trapdoors for block ciphers
, 2018 We provide sufficient conditions to guarantee that a translation based cipher is not vulnerable with respect to the partition-based trapdoor. This trapdoor has been introduced, recently, by Bannier et al.

Imprimitive permutations groups generated by the round functions of key-alternating block ciphers and truncated differential cryptanalysis [PDF]
arXiv, 2006 We answer a question of Paterson, showing that all block systems for the group generated by the round functions of a key-alternating block cipher are the translates of a linear subspace. Following up remarks of Paterson and Shamir, we exhibit a connection to truncated differential cryptanalysis. We also give a condition that guarantees that the group

Molecular Oncology, EarlyView.The authors conducted a retrospective study of 94 patients with advanced cancer who underwent next‐generation sequencing (NGS) gene panel analysis and received targeted treatments when applicable. Results further support evidence indicating that molecular profiling provides clinical benefit.
