Cryptanalysis of S-DES.
K. S. Ooi, Brain Chin Vito · 2002
This paper describes an effort to attack S-DES using differential cryptanalysis and linear cryptanalysis. S-DES is a reduced version of the Data Encryption Standard (DES). It also includes a discussion on the subject of cryptology and a literature survey of useful papers regarding cryptography and cryptanalysis. This paper is meant as a tutorial on the fundamentals of differential cryptanalysis and linear cryptanalysis of a Feistel cipher.
