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.
The Belgian block cipher Rijndael was chosen in 2000 by the U.S. government’s National Institute of Standards and Technology (NIST) to be the successor to the Data Encryption Standard. Rijndael was subsequently standardized as the Advanced Encryption Standard (AES), which is potentially the world’s most important block cipher. In 2002, some new analytical techniques were suggested that may have a dramatic effect on the security of the AES. Existing analytical techniques for block ciphers depend heavily on a statistical approach, whereas these new techniques are algebraic in nature. Algebraic Aspects of the Advanced Encryption Standard, appearing five years after publication of the AES, presents the state of the art for the use of such algebraic techniques in analyzing the AES. The primary audience for this work includes academic and industry researchers in cryptology; the book is also suitable for advanced-level students.
P IConsumer Sourcebook /I provides a comprehensive digest of accessible resources and advisory information for the American consumer.

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.
. . . from expected death comes unexpected new life!" The Gospel of Matthew does not shy away from the realities of struggle, suffering, doubt, and death. Yet, from the first names in the genealogy to the last words spoken by Jesus, the Gospel testifies to the promise that from expected death comes unexpected new life. Through the actions of Tamar, Rahab, Ruth, and Bathsheba, we experience the expectation of death and the promise of unexpected new life. In the birth story of Jesus, Joseph suspects Mary of committing adultery. It is this dilemma that is the focus of the narrative. If he reveals her pregnancy, she could be killed. If he conceals her pregnancy, he will be going against the law of the Lord. What is a righteous man to do? In Joseph's dilemma, this experience of expected death, the Gospel of Matthew proclaims the promise of unexpected new life. The promise of unexpected new life is a theme that continues throughout Matthew's Gospel in the life and ministry of Jesus. The call of his disciples is a call from death to new life. The teaching of Jesus focuses on the experience of death and the promise of new life. In both healing and curing, Jesus brings unexpected new life to those who face death. But it is the death and resurrection of Jesus that is the climax of unexpected new life in the Gospel of Matthew. Even as Jesus experiences a most horrific and humiliating death in the crucifixion, death and the grave do not have the final say. In bearing witness to Jesus' resurrection, the Gospel of Matthew proclaims the magnificent promise of unexpected new life. Matthew J. Marohl invites you in these pages to read the Gospel of Matthew in a new way, from a fresh perspective. Integrating insights from the study of Mediterranean anthropology, Marohl makes the cultural world of the Gospel come alive, so that as you read Matthew again (or perhaps for the first time) you will certainly experience the powerful promise that from expected death comes unexpected new life!
Explore the tenderness and the tensions in the teachings of Jesus. The Gospel of Matthew portrays Jesus and his message as full of tender compassion and urgent warning. This six-part exploration of an enigmatic Gospel takes readers into the themes, topics, and tensions at the heart of Matthew's story about the life and work of Jesus. Chapters focus on blessing and comfort, judgment and retribution, the meaning of discipleship, Jesus’ vision for the Church and world, conflicts and complaints, and how the Gospel of Matthew speaks to believers today. The book can be read alone or used by small groups anytime throughout the year. Components include video teaching sessions featuring Matthew Skinner and a comprehensive Leader Guide.
