Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: A How-to Guide for Implementing Algorithms and Protocols Addressing real-world implementation issues, Understanding and Applying Cryptography and Data Security emphasizes cryptographic algorithm and protocol implementation in hardware, software, and embedded systems. Derived from the author’s teaching notes and research publications, the text is designed for electrical engineering and computer science courses. Provides the Foundation for Constructing Cryptographic Protocols The first several chapters present various types of symmetric-key cryptographic algorithms. These chapters examine basic substitution ciphers, cryptanalysis, the Data Encryption Standard (DES), and the Advanced Encryption Standard (AES). Subsequent chapters on public-key cryptographic algorithms cover the underlying mathematics behind the computation of inverses, the use of fast exponentiation techniques, tradeoffs between public- and symmetric-key algorithms, and the minimum key lengths necessary to maintain acceptable levels of security. The final chapters present the components needed for the creation of cryptographic protocols and investigate different security services and their impact on the construction of cryptographic protocols. Offers Implementation Comparisons By examining tradeoffs between code size, hardware logic resource requirements, memory usage, speed and throughput, power consumption, and more, this textbook provides students with a feel for what they may encounter in actual job situations. A solutions manual is available to qualified instructors with course adoptions.

The purpose of steganography is to hide the presence of a message from the intruder by using state-of-the-art methods, algorithms, architectures, models, and methodologies in the domains of cloud, internet of things (IoT), and the Android platform. Though security controls in cloud computing, IoT, and Android platforms are not much different than security controls in an IT environment, they might still present different types of risks to an organization than the classic IT solutions. Therefore, a detailed discussion is needed in case there is a breach in security. It is important to review the security aspects of cloud, IoT, and Android platforms related to steganography to determine how this new technology is being utilized and improved continuously to protect information digitally. The benefits and challenges, along with the current and potential developments for the future, are important keystones in this critical area of security research. Multidisciplinary Approach to Modern Digital Steganography reviews the security aspects of cloud, IoT, and Android platforms related to steganography and addresses emerging security concerns, new algorithms, and case studies in the field. Furthermore, the book presents a new approach to secure data storage on cloud infrastructure and IoT along with including discussions on optimization models and security controls that could be implemented. Other important topics include data transmission, deep learning techniques, machine learning, and both image and text stenography. This book is essential for forensic engineers, forensic analysts, cybersecurity analysts, cyber forensic examiners, security engineers, cybersecurity network analysts, cyber network defense analysts, and digital forensic examiners along with practitioners, researchers, academicians, and students interested in the latest techniques and state-of-the-art methods in digital steganography.
