Yet Another Algebraic Cryptanalysis of Small Scale Variants of AES

WebAug 3, 2024 · AES-128 encrypts blocks of a 128-bit size. AES-192 encrypts blocks of a 192-bit size. AES-256 encrypts blocks of a 256-bit size. In addition to having different block sizes, each encryption method has a different number of rounds. These rounds are the processes of changing a plaintext piece of data into encrypted data or ciphered text. WebJun 1, 2024 · The small scale variations made in the AES algorithm is bound to enhance the security by hardening the cryptosystem against attacks. From the results, the modified AES key schedule algorithm with active key added sub-function has shown an increase in the confusion and diffusion characteristics gradually showing a Declaration of Competing … WebJun 1, 2024 · Abstract This work presents new advances in algebraic cryptanalysis of small scale derivatives of AES. We model the cipher as a system of polynomial equations over GF (2), which involves only the variables of the initial key, and we subsequently attempt to solve this system using Gröbner bases. chrome pdf 转 图片
