Computer Security and Cryptography by Alan G. Konheim Pdf

Gain the skills and knowledge needed to create effective data security systems This book updates readers with all the tools, techniques, and concepts needed to understand and implement data security systems. It presents a wide range of topics for a thorough understanding of the factors that affect the efficiency of secrecy, authentication, and digital signature schema. Most importantly, readers gain hands-on experience in cryptanalysis and learn how to create effective cryptographic systems. The author contributed to the design and analysis of the Data Encryption Standard (DES), a widely used symmetric-key encryption algorithm. His recommendations are based on firsthand experience of what does and does not work. Thorough in its coverage, the book starts with a discussion of the history of cryptography, including a description of the basic encryption systems and many of the cipher systems used in the twentieth century. The author then discusses the theory of symmetric- and public-key cryptography. Readers not only discover what cryptography can do to protect sensitive data, but also learn the practical limitations of the technology. The book ends with two chapters that explore a wide range of cryptography applications. Three basic types of chapters are featured to facilitate learning: Chapters that develop technical skills Chapters that describe a cryptosystem and present a method of analysis Chapters that describe a cryptosystem, present a method of analysis, and provide problems to test your grasp of the material and your ability to implement practical solutions With consumers becoming increasingly wary of identity theft and companies struggling to develop safe, secure systems, this book is essential reading for professionals in e-commerce and information technology. Written by a professor who teaches cryptography, it is also ideal for students.

Applications of Encryption and Watermarking for Information Security by Mohamed, Boussif Pdf

In recent years, media digitalization has been booming. It has, however, led to a phenomenon of private data hacking, which was stimulated by the expansion of the data exchange system. These hackers are being countered by using new techniques, including cryptography and watermarking. Therefore, in the fields of information security, data encryption, and watermarking, there exists a need for a collection of original research in this area. Applications of Encryption and Watermarking for Information Security provides relevant theoretical frameworks and the latest empirical research findings in the domains of security and privacy. It is written for professionals who want to improve their understanding of the strategic role of trust at different levels of information security, that is, trust at the level of cryptography and watermarking and at the level of securing multimedia data. Covering topics such as background subtraction, moving object detection, and visual watermark identification, this premier reference source is an excellent resource for security and privacy professionals, IT managers, practitioners, students and educators of higher education, librarians, researchers, and academicians.

Cryptography and Steganography. A multilayer Data Security Approach by Jagdish Chandra Patni,Hitesh Kumar Sharma Pdf

Document from the year 2021 in the subject Computer Science - IT-Security, grade: 2, , language: English, abstract: This book focuses on the implementation of Image steganography and modifying the existing technique to add more security to a normal steganography technique. The Book emphasizes various techniques used in steganography with methodology, algorithm, MAT LAB implementation and implementation in Java. There is data everywhere, in the form of images, text and audio/video files. Some data is very crucial or personal and needs to be kept confidential. For that reason, we have cryptography. Cryptography is the science of encrypting a message such that an unauthorized party cannot comprehend what that message means. Only those who possess the key can decrypt the message. There might be cases where just encrypting the information is not enough, since an encrypted message can raise suspicion. Steganography is the science of hiding a message completely inside another form of data so that the existence of the actual message is not revealed during communication. It is possible to hide the image in any of the digital formats whether it is images, videos or even audio files. Images are popular because they are really frequent on the internet and hence do not arouse suspicion. This book intends to give an overview cryptography with image steganography.

This book provides state-of-the-art coverage of the principles, techniques, and management of issues in cyber security, including threat attacks, privacy, signature and encryption schemes. One of the most important topics addressed concerns lightweight solutions for public key encryption in resource-constrained environments; the book highlights the latest developments in this area. Authentication is another central issue in cyber security. In this book, we address this aspect and sub-aspects ranging from cryptographic approaches to practical design issues, such as CAPTCHA. Privacy is another main topic that is discussed in detail, from techniques for enhancing privacy to pseudonymous schemes. Addressing key issues in the emerging field of cyber security, this book effectively bridges the gap between computer security and threat attacks, and showcases promising applications involving cryptography and security.
