Best Computer Cryptography

Rather than merely showing how to run existing exploits, author Jon Erickson explains how arcane hacking techniques actually work. This book will teach you how to: – Program computers using C, assembly language, and shell scripts. – Corrupt system memory to run arbitrary code using buffer overflows and format strings. – Inspect processor registers and system memory with a debugger to gain a real understanding of what is happening. – Outsmart common security measures like nonexecutable stacks and intrusion detection systems. – Gain access to a remote server using port-binding or connect-back shellcode, and alter a server's logging behavior to hide your presence. – Redirect network traffic, conceal open ports, and hijack TCP connections. – Crack encrypted wireless traffic using the FMS attack, and speed up brute-force attacks using a password probability matrix. Jon Erickson has a formal education in computer science and speaks frequently at computer security conferences around the world.

From Mary, Queen of Scots, trapped by her own code, to the Navajo Code Talkers who helped the Allies win World War II, to the incredible (and incredibly simple) logisitical breakthrough that made Internet commerce secure, The Code Book tells the story of the most powerful intellectual weapon ever known: secrecy. In the information age, the fear that drives cryptographic improvements is both capitalistic and libertarian--corporations need encryption to ensure that their secrets don't fall into the hands of competitors and regulators, and ordinary people need encryption to keep their everyday communications private in a free society. Similarly, the battles for greater decryption power come from said competitors and governments wary of insurrection.

A reorganized and comprehensive major revision of a classic book, this edition provides a bridge between introductory digital communications and more advanced treatment of information theory. In 1970 the first author published a book entitled An Introduction to Error-Correcting Codes, which presented the fundamentals of the previous two decades of work covering both block and convolutional codes. Other major additions included a comprehensive treatment of the error-detecting capabilities of block codes and an emphasis on soft decoding methods for convolutional codes. Three of these new developments stand out in particular: the application of binary convolutional and block codes to expanded (nonbinary) modulation alphabets, the development of practical soft decoding methods for block codes, and the discovery of soft-input, soft-output iterative decoding techniques for block and convolutional codes. A total of seven new chapters covering these topics have been added to this edition: two chapters on trellis- and block-coded modulation techniques, three chapters on soft decoding methods for block codes, and two chapters on turbo and low-density parity-check codes and iterative decoding. Chapters 3 through 10 cover in detail the fundamentals of block codes. Chapter 8 provides detailed coverage of majority-logic decodable codes, including the important classes of Euclidean and projective geometry codes. Chapter 9 develops the theory of the trellis structure of block codes, laying the groundwork for the introduction of trellis-based soft decoding algorithms in Chapter 14. Chapter 10, written by Professor Marc Fossorier, presents comprehensive coverage of reliability-based soft decoding methods for block codes and includes an introduction to iterative decoding techniques. Convolutional codes are introduced in Chapter 11, with the encoder state diagram serving as the basis for studying code structure and distance properties. Chapter 12 covers optimum decoding methods for convolutional codes, with an emphasis on the (maximum likelihood) Viterbi decoding algorithm for both hard and soft demodulator decisions. Chapter 13 covers suboptimum decoding methods for convolutional codes, with an emphasis on sequential decoding, using both the ZJ (stack) and Fano algorithms, and majority-logic decoding. Chapter 14 extends the soft decoding methods introduced for convolutional codes in Chapter 12 to block codes. This completely new chapter makes extensive use of the block code trellis structures introduced in Chapter 9. Chapter 15 discusses the important concepts of code concatenation, multistage decoding, and code decomposition. Chapter 16 introduces the area of parallel concatenation, or turbo coding, and its related iterative decoding techniques based on the BCJR algorithm presented in Chapter 12. Both block (Chapter 20) and convolutional (Chapter 21) burst-error-correcting codes are included. As a text the book can be used as the basis for a two-semester sequence in coding theory, with Chapters 1-10 on the fundamentals of block codes covered in one semester and the remaining chapters on convolutional codes and advanced block code topics in a second semester. Another possibility is to cover Chapters 1-8 and 11-13, which include the fundamentals of both block and convolutional codes, in one semester, followed by a second semester devoted to advanced topics. A course on block codes comprise Chapters 1-7 plus selected topics from Chapters 8-10, 14-15, 17, 19-20, and 22, whereas Chapters 1, 11-13, 16, 18, and 21 provide a thorough coverage of convolutional codes.

Using dozens of examples, The Only Grammar Book You'll Ever Need provides guidelines for: Understanding the parts of speech and elements of a sentence Avoiding the most common grammar and punctuation mistakes Using correct punctuating in every sentence Writing clearly and directly Approaching writing projects, whether big or small. She edits and publishes Class Act, a national magazine that features grammar, writing, and ideas for English teachers, and has written more than fifty articles on English instruction, as well as a number of study guides. If a sentence contains a misplaced or dangling modifier or is essentially illogical, it becomes confusing at best and ludicrous at worst. This chapter will give you some pointers for looking critically at your sentence construction as well as the tools to fix any problems you find. The way the sentence is written, the ambulance driver is barely speaking—but surely that’s not what the writer meant. Witnesses reported that the woman was driving the getaway car with flowing black hair. Witnesses reported that the woman with flowing black hair was driving the getaway car. Mrs. Anderson could not stop thinking about her sick baby running in the six-mile road race. The clause running in the six-mile road race is out of place; it should be closer to the noun it modifies (Mrs. Anderson).
