The Block Cipher Companion


Book Description

Block ciphers encrypt blocks of plaintext, messages, into blocks of ciphertext under the action of a secret key, and the process of encryption is reversed by decryption which uses the same user-supplied key. Block ciphers are fundamental to modern cryptography, in fact they are the most widely used cryptographic primitive – useful in their own right, and in the construction of other cryptographic mechanisms. In this book the authors provide a technically detailed, yet readable, account of the state of the art of block cipher analysis, design, and deployment. The authors first describe the most prominent block ciphers and give insights into their design. They then consider the role of the cryptanalyst, the adversary, and provide an overview of some of the most important cryptanalytic methods. The book will be of value to graduate and senior undergraduate students of cryptography and to professionals engaged in cryptographic design. An important feature of the presentation is the authors' exhaustive bibliography of the field, each chapter closing with comprehensive supporting notes.




Smart Card. Research and Applications


Book Description

Smart cards have been driven by the need for a secure, portable, computing platform. Hence it is no surprise that security considerations dominated their research. The CARDIS conferences were created to provide a forum for this research. CARDIS 1998 is the third international conference on Smart Card Research and Advanced Applications, held in Louvain-la-Neuve, Belgium, 14-16 Sept- ber 1998. The ?rst CARDIS was held in Lille, France in November 1994, and the second was held in Amsterdam, The Netherlands in September 1996. The fourth CARDIS is scheduled to take place in Bristol, UK in September 2000 (http://www.cardis.org). This volume contains the refereed papers presented at CARDIS 1998. These 35 papers were ?rst published in a pre-proceedings and distributed to the - tendees at the conference; they have subsequently been revised and updated for this volume. The papers discuss all aspects of smart-card research: Java cards, elect- nic commerce applications, e?ciency, security (including cryptographic al- rithms, cryptographic protocols, and authentication), and architecture. Subm- sions from Europe, the U.S., Asia, and Australia show that this is indeed an international area of research, and one that is becoming more popular as pr- tical demand for smart cards increase. We wish to thank the Program Committee members who did an excellent job in reviewing papers and providing feedback to the authors.




Lai-Massey Cipher Designs


Book Description

This book provides the first extensive survey of block ciphers following the Lai-Massey design paradigm. After the introduction, with historical remarks, the author structures the book into a chapter on the description of the PES, IDEA and other related ciphers, followed by a chapter on cryptanalysis of these ciphers, and another chapter on new cipher designs. The appendices include surveys of cryptographic substitution boxes and of MDS codes. This comprehensive treatment can serve as a reference source for researchers, students and practitioners.




Security of Block Ciphers


Book Description

A comprehensive evaluation of information security analysis spanning the intersection of cryptanalysis and side-channel analysis Written by authors known within the academic cryptography community, this book presents the latest developments in current research Unique in its combination of both algorithmic-level design and hardware-level implementation; this all-round approach - algorithm to implementation – covers security from start to completion Deals with AES (Advanced Encryption standard), one of the most used symmetric-key ciphers, which helps the reader to learn the fundamental theory of cryptanalysis and practical applications of side-channel analysis




The Design of Rijndael


Book Description

An authoritative and comprehensive guide to the Rijndael algorithm and Advanced Encryption Standard (AES). AES is expected to gradually replace the present Data Encryption Standard (DES) as the most widely applied data encryption technology. This book, written by the designers of the block cipher, presents Rijndael from scratch. The underlying mathematics and the wide trail strategy as the basic design idea are explained in detail and the basics of differential and linear cryptanalysis are reworked. Subsequent chapters review all known attacks against the Rijndael structure and deal with implementation and optimization issues. Finally, other ciphers related to Rijndael are presented.







New Stream Cipher Designs


Book Description

This state-of-the-art survey presents the outcome of the eSTREAM Project, which was launched in 2004 as part of ECRYPT, the European Network of Excellence in Cryptology (EU Framework VI). The goal of eSTREAM was to promote the design of new stream ciphers with a particular emphasis on algorithms that would be either very fast in software or very resource-efficient in hardware. Algorithm designers were invited to submit new stream cipher proposals to eSTREAM, and 34 candidates were proposed from around the world. Over the following years the submissions were assessed with regard to both security and practicality by the cryptographic community, and the results were presented at major conferences and specialized workshops dedicated to the state of the art of stream ciphers. This volume describes the most successful of the submitted designs and, over 16 chapters, provides full specifications of the ciphers that reached the final phase of the eSTREAM project. The book is rounded off by two implementation surveys covering both the software- and the hardware-oriented finalists.




Differential Cryptanalysis of the Data Encryption Standard


Book 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.




Fast Software Encryption


Book Description

This book constitutes the thoroughly refereed post-proceedings of the 8th International Workshop on Fast Software Encryption, FSE 2001, held in Yokohama, Japan in April 2001.The 27 revised full papers presented together with one invited paper were carefully reviewed and selected from 46 submissions. The papers are organized in topical sections on cryptanalysis of block ciphers, hash functions and Boolean functions, modes of operation, cryptanalysis of stream ciphers, pseudo-randomness, and design and evaluation.
