商品描述

In the digital world, the need to protect communications increases every day. While traditional digital encryption methods are useful, there are many other options for hiding your information. Information Hiding in Speech Signals for Secure Communication provides a number of methods to hide secret speech information using a variety of digital speech coding standards. Professor Zhijun Wu has conducted years of research in the field of speech information hiding, and brings his state-of-the-art techniques to readers of this book, including a mathematical model for information hiding, the core concepts of secure speech communication, the ABS-based information hiding algorithm, and much more.

This book shows how to implement a secure speech communication system, including applications to various network security states. Readers will find information hiding algorithms and techniques (embedding and extracting) that are capable of withstanding the advanced forms of attack. The book presents concepts and applications for all of the most widely used speech coding standards, including G.711, G.721, G.728, G.729 and GSM, along with corresponding hiding and extraction algorithms. Readers will also learn how to use a speech covert communication system over an IP network as well as a speech secure communication system applied in PSTN.

  • Presents information hiding theory and the mathematical model used for information hiding in speech.
  • Provides a number of methods to hide secret speech information using the most common digital speech coding standards.
  • A combination of practice and theory enables programmers and system designers not only to implement tried and true encryption procedures, but also to consider probable future developments in their designs.

商品描述(中文翻譯)

在數位世界中,保護通訊的需求每天都在增加。儘管傳統的數位加密方法很有用,但還有許多其他選項可以隱藏您的信息。《在語音信號中隱藏信息以實現安全通訊》提供了多種方法,使用各種數位語音編碼標準來隱藏秘密語音信息。吳志軍教授在語音信息隱藏領域進行了多年的研究,並將他的最新技術帶給本書的讀者,包括信息隱藏的數學模型、安全語音通訊的核心概念、基於ABS的信息隱藏算法等等。

本書展示了如何實現安全的語音通訊系統,包括應用於各種網絡安全狀態的應用。讀者將找到能夠抵禦先進攻擊形式的信息隱藏算法和技術(嵌入和提取)。本書介紹了所有最常用的語音編碼標準(包括G.711、G.721、G.728、G.729和GSM),以及相應的隱藏和提取算法。讀者還將學習如何在IP網絡上使用語音隱蔽通訊系統,以及如何在PSTN中應用語音安全通訊系統。

本書介紹了信息隱藏理論和用於語音信息隱藏的數學模型。它提供了使用最常見的數位語音編碼標準來隱藏秘密語音信息的多種方法。實踐和理論的結合使得程序員和系統設計師不僅能夠實施經過驗證的加密程序,還能夠考慮到其設計中可能出現的未來發展。
