Differential Cryptanalysis of the Data Encryption Standard

Description

DES, the Data Encryption Standard, is the best known and most widely used civilian cryptosystem. It was developed by IBM and adopted as a US national standard in the mid 1970`s, and had resisted all attacks in the last 15 years. This book presents the first successful attack which can break the full 16 round DES faster than via exhaustive search. It describes in full detail, the novel technique of Differential Cryptanalysis, and demonstrates its applicability to a wide variety of cryptosystems and hash functions, including FEAL, Khafre, REDOC-II, LOKI, Lucifer, Snefru, N-Hash, and many modified versions of DES. The methodology used offers valuable insights to anyone interested in data security and cryptography, and points out the intricacies of developing, evaluating, testing, and implementing such schemes. This book was written by two of the field`s leading researchers, and describes state-of-the-art research in a clear and completely contained manner Front Matter....Pages i-ix Introduction....Pages 1-6 Results....Pages 7-10 Introduction to Differential Cryptanalysis....Pages 11-32 Differential Cryptanalysis of DES Variants....Pages 33-77 Differential Cryptanalysis of the Full 16-Round DES....Pages 79-88 Differential Cryptanalysis of FEAL....Pages 89-107 Differential Cryptanalysis of Other Cryptosystems....Pages 109-131 Differential Cryptanalysis of Hash Functions....Pages 133-148 Non-Differential Cryptanalysis of DES with a Small Number of Rounds....Pages 149-154 Back Matter....Pages 155-188
