Abstract: The block cipher is a main-stream means to provide confidentiality for data transmitted in insecure communication environments, and the S-box is an essential part in most of modern block ...

Sony announced late last week that they have invented a new encryption mechanism known as "CLEFIA," a block cipher algorithm designed to help content producers deliver "advanced copy protection" with ...

Block ciphers, a branch of modern cryptography, are playing a more prominent role in protecting information security as 5G technology develops. Although encryption algorithms of the traditional ...

A proprietary algorithm developed by RSA Data Security, Inc., RC2 is an alternative to DES. The algorithm expands a single message by up to 8 bytes. RC2 is a block cipher that encrypts data in blocks ...

This repository implements an example attack against single blocks of AES-CBC encrypted ciphertext using a padding oracle to determine the plaintext. This is by no means an attack tool, it merely ...
