Group Theoretic Cryptography


Book Description

Group theory appears to be a promising source of hard computational problems for deploying new cryptographic constructions. This reference focuses on the specifics of using groups, including in particular non-Abelian groups, in the field of cryptography. It provides an introduction to cryptography with emphasis on the group theoretic perspective, making it one of the first books to use this approach. The authors provide the needed cryptographic and group theoretic concepts, full proofs of essential theorems, and formal security evaluations of the cryptographic schemes presented. They also provide references for further reading and exercises at the end of each chapter.

Coding, Cryptography and Combinatorics


Book Description

It has long been recognized that there are fascinating connections between cod ing theory, cryptology, and combinatorics. Therefore it seemed desirable to us to organize a conference that brings together experts from these three areas for a fruitful exchange of ideas. We decided on a venue in the Huang Shan (Yellow Mountain) region, one of the most scenic areas of China, so as to provide the additional inducement of an attractive location. The conference was planned for June 2003 with the official title Workshop on Coding, Cryptography and Combi natorics (CCC 2003). Those who are familiar with events in East Asia in the first half of 2003 can guess what happened in the end, namely the conference had to be cancelled in the interest of the health of the participants. The SARS epidemic posed too serious a threat. At the time of the cancellation, the organization of the conference was at an advanced stage: all invited speakers had been selected and all abstracts of contributed talks had been screened by the program committee. Thus, it was de cided to call on all invited speakers and presenters of accepted contributed talks to submit their manuscripts for publication in the present volume. Altogether, 39 submissions were received and subjected to another round of refereeing. After care ful scrutiny, 28 papers were accepted for publication.




The Photograph


Book Description

"One of Britain's most talented and experienced writers. The closer you look the more mystery you see." --The Times (London) A seductive and hugely suspenseful novel by Booker Prize winning author Penelope Lively, about what can happen when you look too closely into the past Searching through a little-used cupboard at home, Glyn Peters chances upon a photograph he has never seen before. Taken in high summer, many years earlier, it shows his wife, Kath, holding hands with another man. Glyn's work as a historian should have prepared him for unexpected findings and reversals, but he is ill-prepared for this radical shift in perception. His mind fills with questions. Who was the man? Who took the photograph? Where was it taken? When? Had Kath planned for him to find out all along? As Glyn begins to search for answers, he, and those around him, find the certainties of the past and present slip away, and the picture of the beautiful woman they all thought they knew distort. Propelled by the author’s signature mastery of narrative and psychology, The Photograph is Lively at her very best.




Gröbner Bases, Coding, and Cryptography


Book Description

Coding theory and cryptography allow secure and reliable data transmission, which is at the heart of modern communication. Nowadays, it is hard to find an electronic device without some code inside. Gröbner bases have emerged as the main tool in computational algebra, permitting numerous applications, both in theoretical contexts and in practical situations. This book is the first book ever giving a comprehensive overview on the application of commutative algebra to coding theory and cryptography. For example, all important properties of algebraic/geometric coding systems (including encoding, construction, decoding, list decoding) are individually analysed, reporting all significant approaches appeared in the literature. Also, stream ciphers, PK cryptography, symmetric cryptography and Polly Cracker systems deserve each a separate chapter, where all the relevant literature is reported and compared. While many short notes hint at new exciting directions, the reader will find that all chapters fit nicely within a unified notation.

Airbrushing and Finishing Scale Models


Book Description

Brett Green details the prerequisites of airbrushing, including the different types of spray equipment and air sources available, offering advice on appropriate thinners, paint ratios and air pressures to ensure the most appropriate paint coverage across a range of different airbrushing applications. He then examines various airbrushing techniques across a wide range of models. Ten step-by-step, illustrated studies ranging from weathered military aircraft to pristine, high gloss motor vehicles, science fiction models, fantasy figures, groundwork and buildings will complete this in-depth guide to getting the best results on your models.




Working Girls


Book Description

Working Girls offers a cultural and literary history of telegraphists, typists, shop-girls, and barmaids. It argues that these occupations helped to shape a distinctively new identity for emancipated young women, and explores how authors used this to navigate a precarious literary landscape.
