Abstract: From the Publisher:
In October 2000, the US National Institute of Standards and Technology selected the block cipher Rijndael as the 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 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.|This volume is THE authoritative guide to the Rijndael algorithm and AES. Professionals, researchers, and students active or interested in data encryption will find it a valuable source of information and reference.
TL;DR: The 'Caesar' Cypher shows how old encryption is and how simple old ciphers now are for us to break.
Abstract: Ever since humans started talking, we have been trying to work out a way of communicating information to one person, while keeping it secret from everyone else. Certainly, when you start to look at encryption methods, you are introduced to the 'Caesar' Cypher. which shows how old encryption is and how simple old ciphers now are for us to break.
TL;DR: The Advanced Encryption Standard (AES), which has been approved after an international competition by the National Institute of Standards and Technology, is described.
Abstract: In this paper, we describe the Advanced Encryption Standard (AES), which has been approved after an international competition by the National Institute of Standards and Technology.
TL;DR: A new 128-bit block cipher called Square, which concentrates on the resistance against differential and linear cryptanalysis, and the publication of the resulting cipher for public scrutiny is published.
Abstract: In this paper we present a new 128-bit block cipher called Square. The original design of Square concentrates on the resistance against differential and linear cryptanalysis. However, after the initial design a dedicated attack was mounted that forced us to augment the number of rounds. The goal of this paper is the publication of the resulting cipher for public scrutiny. A C implementation of Square is available that runs at 2.63 MByte/s on a 100 MHz Pentium. Our M68HC05 Smart Card implementation fits in 547 bytes and takes less than 2 msec. (4 MHz Clock). The high degree of parallellism allows hardware implementations in the Gbit/s range today.
