A Methodology for the Cryptanalysis of Classical Ciphers with Search Metaheuristics
Author: George Lasry
Publisher: kassel university press GmbH
ISBN: 3737604584
Category :
Languages : en
Pages : 249
Book Description
Cryptography, the art and science of creating secret codes, and cryptanalysis, the art and science of breaking secret codes, underwent a similar and parallel course during history. Both fields evolved from manual encryption methods and manual codebreaking techniques, to cipher machines and codebreaking machines in the first half of the 20th century, and finally to computerbased encryption and cryptanalysis from the second half of the 20th century. However, despite the advent of modern computing technology, some of the more challenging classical cipher systems and machines have not yet been successfully cryptanalyzed. For others, cryptanalytic methods exist, but only for special and advantageous cases, such as when large amounts of ciphertext are available. Starting from the 1990s, local search metaheuristics such as hill climbing, genetic algorithms, and simulated annealing have been employed, and in some cases, successfully, for the cryptanalysis of several classical ciphers. In most cases, however, results were mixed, and the application of such methods rather limited in their scope and performance. In this work, a robust framework and methodology for the cryptanalysis of classical ciphers using local search metaheuristics, mainly hill climbing and simulated annealing, is described. In an extensive set of case studies conducted as part of this research, this new methodology has been validated and demonstrated as highly effective for the cryptanalysis of several challenging cipher systems and machines, which could not be effectively cryptanalyzed before, and with drastic improvements compared to previously published methods. This work also led to the decipherment of original encrypted messages from WWI, and to the solution, for the first time, of several public cryptographic challenges.

Computational Cryptography
Author: Joppe Bos
Publisher:
ISBN: 1108848427
Category : Language Arts & Disciplines
Languages : en
Pages : 402
Book Description
The area of computational cryptography is dedicated to the development of effective methods in algorithmic number theory that improve implementation of cryptosystems or further their cryptanalysis. This book is a tribute to Arjen K. Lenstra, one of the key contributors to the field, on the occasion of his 65th birthday, covering his best-known scientific achievements in the field. Students and security engineers will appreciate this no-nonsense introduction to the hard mathematical problems used in cryptography and on which cybersecurity is built, as well as the overview of recent advances on how to solve these problems from both theoretical and practical applied perspectives. Beginning with polynomials, the book moves on to the celebrated Lenstra-Lenstra-Lovász lattice reduction algorithm, and then progresses to integer factorization and the impact of these methods to the selection of strong cryptographic keys for usage in widely used standards.

The Gambler and the Scholars
Author: John F. Dooley
Publisher: Springer Nature
ISBN: 303128318X
Category : Computers
Languages : en
Pages : 332
Book Description
In May 1917, William and Elizebeth Friedman were asked by the U.S. Army to begin training officers in cryptanalysis and to decrypt intercepted German diplomatic and military communications. In June 1917, Herbert Yardley convinced the new head of the Army’s Military Intelligence Division to create a code and cipher section for the Army with himself as its head. These two seminal events were the beginning of modern American cryptology, the growth of which culminated 35 years later with the creation of the National Security Agency. Each running their own cryptologic agencies in the 1920s, the Friedman-Yardley relationship was shattered after Yardley published a tell-all book about his time in military intelligence. Yet in the end, the work they all started in 1917 led directly to the modern American intelligence community. As they got older, they became increasingly irrelevant in the burgeoning American cryptologic fraternity. Topics and features: * Examines the lives of three remarkable and pioneering cryptologists * Offers fascinating insights into spies, codes and ciphers, rumrunners, poker, and military history * Sheds new light on interesting parts of the cryptologists’ careers—especially Elizebeth Friedman, whose work during World War II has just begun to be explored * Recounts several good stories, i.e., What if the Friedmans had gone to work for Herbert Yardley in his new Cipher Bureau in 1919? What if Yardley had moved back to Washington to work for William Friedman a decade later? This enjoyable book has wide appeal for: general readers interested in the evolution of American cryptology, American historians (particularly of World War I, the inter-war period, and World War II signals intelligence), and historians of—and general readers interested in—American military intelligence. It also can be used as an auxiliary text or recommended reading in introductory or survey courses in history or on the related topics.

Algebraic Cryptanalysis
Author: Gregory Bard
Publisher: Springer Science & Business Media
ISBN: 0387887571
Category : Computers
Languages : en
Pages : 372
Book Description
Algebraic Cryptanalysis bridges the gap between a course in cryptography, and being able to read the cryptanalytic literature. This book is divided into three parts: Part One covers the process of turning a cipher into a system of equations; Part Two covers finite field linear algebra; Part Three covers the solution of Polynomial Systems of Equations, with a survey of the methods used in practice, including SAT-solvers and the methods of Nicolas Courtois. Topics include: Analytic Combinatorics, and its application to cryptanalysis The equicomplexity of linear algebra operations Graph coloring Factoring integers via the quadratic sieve, with its applications to the cryptanalysis of RSA Algebraic Cryptanalysis is designed for advanced-level students in computer science and mathematics as a secondary text or reference book for self-guided study. This book is suitable for researchers in Applied Abstract Algebra or Algebraic Geometry who wish to find more applied topics or practitioners working for security and communications companies.
