The SPEEDY Family of Block Ciphers - Engineering an Ultra Low-Latency Cipher from Gate Level for Secure Processor Architectures

IACR Cryptology ePrint Archive, 2021
We introduce SPEEDY, a family of ultra low-latency block ciphers. We mix engineering expertise into each step of the cipher’s design process in order to create a secure encryption primitive with an extremely low latency in CMOS hardware.

Exon skipping caused by a complex structural variation in SH2D1A resulted in X‐linked lymphoproliferative syndrome type 1

Molecular Genetics & Genomic Medicine, 2022
Background X‐linked lymphoproliferative syndrome type 1 (XLP1) is a rare primary immunodeficiency disorder characterized by severe immune dysregulation often after viral infection. It is caused by hemizygous mutations in the X‐linked SH2D1A gene.

Reflection ciphers [PDF]

Designs, Codes and Cryptography, 2015
This paper investigates ciphers where the set of encryption functions is identical to the set of decryption functions, which we call reflection ciphers. Equivalently, there exists a permutation P, named the coupling permutation, such that decryption under k corresponds to encryption under P(k).

A Novel Grayscale Image Encryption Scheme Based on the Block-Level Swapping of Pixels and the Chaotic System

Sensors, 2022
Hundreds of image encryption schemes have been conducted (as the literature review indicates). The majority of these schemes use pixels as building blocks for confusion and diffusion operations.

A New Random Keys Generator Depend on Multi Techniques [PDF]

Engineering and Technology Journal, 2015
A stream cipher is a symmetric cipher which operates with a time-varying transformation onIndividual plaintext digits. By contrast, block ciphers operate with a fixed transformation on large blocks of plaintext digits.
