商品描述

Cryptology is the practice of hiding digital information by means of various obfuscatory and steganographic techniques. The application of said techniques facilitates message confidentiality and sender/receiver identity authentication, and helps to ensure the integrity and security of computer passwords, ATM card information, digital signatures, DVD and HDDVD content, and electronic commerce. Cryptography is also central to digital rights management (DRM), a group of techniques for technologically controlling the use of copyrighted material that is being widely implemented and deployed at the behest of corporations that own and create revenue from the hundreds of thousands of mini-transactions that take place daily on programs like iTunes.

This new edition of our best-selling book on cryptography and information hiding delineates a number of different methods to hide information in all types of digital media files. These methods include encryption, compression, data embedding and watermarking, data mimicry, and scrambling. During the last 5 years, the continued advancement and exponential increase of computer processing power have enhanced the efficacy and scope of electronic espionage and content appropriation. Therefore, this edition has amended and expanded outdated sections in accordance with new dangers, and includes 5 completely new chapters that introduce newer more sophisticated and refined cryptographic algorithms and techniques (such as fingerprinting, synchronization, and quantization) capable of withstanding the evolved forms of attack.

Each chapter is divided into sections, first providing an introduction and high-level summary for those who wish to understand the concepts without wading through technical explanations, and then presenting concrete examples and greater detail for those who want to write their own programs. This combination of practicality and theory allows programmers and system designers to not only implement tried and true encryption procedures, but also consider probable future developments in their designs, thus fulfilling the need for preemptive caution that is becoming ever more explicit as the transference of digital media escalates.



  • Includes 5 completely new chapters that delineate the most current and sophisticated cryptographic algorithms, allowing readers to protect their information against even the most evolved electronic attacks.

  • Conceptual tutelage in conjunction with detailed mathematical directives allows the reader to not only understand encryption procedures, but also to write programs which anticipate future security developments in their design.

  • Grants the reader access to online source code which can be used to directly implement proven cryptographic procedures such as data mimicry and reversible grammar generation into their own work.

商品描述(中文翻譯)

密碼學是通過各種混淆和隱藏技術來隱藏數字信息的實踐。應用這些技術可以實現消息的保密性和發送者/接收者身份驗證,並有助於確保計算機密碼、ATM卡信息、數字簽名、DVD和HDDVD內容以及電子商務的完整性和安全性。密碼學也是數字版權管理(DRM)的核心,DRM是一組用於技術上控制版權材料使用的技術,目前在像iTunes這樣的程序上廣泛實施和部署,以滿足擁有和從每天數十萬次小型交易中獲利的公司的要求。

我們暢銷書籍《密碼學與信息隱藏》的新版詳細介紹了在各種類型的數字媒體文件中隱藏信息的多種方法。這些方法包括加密、壓縮、數據嵌入和水印、數據模仿和混淆。在過去的5年中,計算機處理能力的持續提升和指數級增長增強了電子間諜活動和內容盗用的效力和範圍。因此,本版根據新的危險修訂和擴展了過時的部分,並包括5個全新章節,介紹了更先進、更精細的密碼算法和技術(如指紋識別、同步和量化),能夠抵禦進化的攻擊形式。

每個章節分為幾個部分,首先提供簡介和高層次摘要,以便那些希望理解概念而不想深入技術解釋的讀者,然後為那些希望編寫自己程序的讀者提供具體示例和更多細節。這種實用性和理論結合的方式使程序員和系統設計師不僅能夠實施經過驗證的加密程序,還能夠考慮其設計中可能出現的未來發展,從而滿足隨著數字媒體轉移的需求的預防性謹慎。

本書包含5個全新章節,詳細介紹了最新和最複雜的密碼算法,讓讀者能夠保護自己的信息免受最先進的電子攻擊。概念教學結合詳細的數學指導,使讀者不僅能夠理解加密程序,還能夠在設計中預見未來安全發展。讀者還可以獲得在線源代碼的訪問權限,可以直接將已證明的加密程序(如數據模仿和可逆語法生成)應用於自己的工作中。
