This book traces a remarkable path of mathematical connections through seemingly disparate topics. Frustrations with a 1940's electro-mechanical computer at a premier research laboratory begin this story. Subsequent mathematical methods of encoding messages to ensure correctness when transmitted over noisy channels lead to discoveries of extremely efficient lattice packings of equal-radius balls, especially in 24-dimensional space. In turn, this highly symmetric lattice, with each point neighboring exactly 196,560 other points, suggested the possible presence of new simple groups as groups of symmetries. Indeed, new groups were found and are now part of the "Enormous Theorem"—the classification of all simple groups whose entire proof runs some 10,000+ pages—and these connections, along with the fascinating history and the proof of the simplicity of one of those "sporatic" simple groups, are presented at an undergraduate mathematical level.

Cryptographic Boolean Functions and Applications, Second Edition is designed to be a comprehensive reference for the use of Boolean functions in modern cryptography. While the vast majority of research on cryptographic Boolean functions has been achieved since the 1970s, when cryptography began to be widely used in everyday transactions, in particular banking, relevant material is scattered over hundreds of journal articles, conference proceedings, books, reports and notes, some of them only available online. This book follows the previous edition in sifting through this compendium and gathering the most significant information in one concise reference book. The work therefore encompasses over 600 citations, covering every aspect of the applications of cryptographic Boolean functions. Since 2008, the subject has seen a very large number of new results, and in response, the authors have prepared a new chapter on special functions. The new edition brings 100 completely new references and an expansion of 50 new pages, along with heavy revision throughout the text. - Presents a foundational approach, beginning with the basics of the necessary theory, then progressing to more complex content - Includes major concepts that are presented with complete proofs, with an emphasis on how they can be applied - Includes an extensive list of references, including 100 new to this edition that were chosen to highlight relevant topics - Contains a section on special functions and all-new numerical examples

Never trust a man That's what Dixie Cash learned from her mother. That and fathers don't stick around. She's pretty independent, and doesn't need help from her baby's daddy, sexy rodeo rider and ex-soldier Gavin Tucker. But he seems determined to do right by her. Just as Dixie starts to imagine that together they might be a family, tragedy strikes--and Gavin shows his true colors. She knew he wasn't honorable After what Gavin went through in Afghanistan, he was more than happy to lose himself in the rodeo circuit--and in sweet Dixie's arms. But doing the right thing can be hard sometimes, and when Dixie--Gavin's lifeline--doesn't need him anymore, he's at a loss. His heart still longs for her, though he's not sure he deserves a second chance....

She Doesn't Need His Protection! Hard working cowboy Johnny Cash has always been a protector to his little sister's best friend, sweet but tough cowgirl Shannon Douglas. It's pretty crazy for girls to ride bulls—yet it's her life to live. Then he realizes he's got some purely male instincts toward her, too. But absolutely no way can he fall for his boss's daughter—if he loses his job, there'll be hell to pay at home…. Shannon was raised to be strong and independent. She wants a national title so bad she can taste it—and she needs Johnny's help. His protectiveness drives her crazy…the same way his kisses do. But she's not about to hang up her bull rope because of him! Her heart says he's the one—but her own stubborn streak might push away the only man who might actually understand her.
