描述.Covering classical cryptography, modern cryptography, and steganography, this volume details how data can be kept secure and private. Each topic is presented and explained by describing various methods, techniques, and algorithms. Moreover, there are numerous helpful examples to reinforce the reader‘s understanding and expertise with these techniques and methodologies....Features & Benefits:..* Incorporates both data encryption and data hiding ..* Supplies a wealth of exercises and solutions to help readers readily understand the material..* Presents information in an accessible, nonmathematical style..* Concentrates on specific methodologies that readers can choose from and pursue, for their data-security needs and goals..* Describes new topics, such as the advanced encryption standard (Rijndael), quantum cryptography, and elliptic-curve cryptography....The book, with its accessible style, is an essential companion for all security practitioners and professionals who need to understand and effectively use both information hiding and encryption to protect digital data and communications. It is also suitable for self-study in the areas of programming, software engineering, and secu

Random Numbers used, the Vigenère method (and also other polyalphabetic ciphers) produces ciphertext with a uniform distribution of letters. The only way to decipher such ciphertext, even if the encryption method is known, is to try all possible keys. This, however, is impractical even with the help of a fast com

This chapter concentrates on the most famous of those machines, namely the German Enigma, used during the Second World War. Following a short discussion of simple rotor encryption machines (Sectio

Stream Ciphersital computer which uses binary numbers, secure codes had to be based on bits. If the plaintext is text, then it is represented internally either in ASCII, with eight bits per character (seven code bits and one parity bit) or in Unicode, with 16 bits per character.

Block Ciphersrning each block of plain-text (plainblock) into a block of ciphertext (cipherblock) that has the same size. The same algorithm is used to encrypt all the blocks, and this algorithm should preferably be reversible. A reversible algorithm simplifies any implementations (software or hardware) because

Quantum Cryptographyk RSA-encrypted messages. In the future, however, this situation may change. After hundreds of years of effort, no efficient factoring algorithm has been found, so the chance that such an algorithm exists seems slim. However, until it is proved that such an algorithm does not exist, the possibility

Data Hiding in Images.. This approach has two disadvantages: the information hiding capacity of a cover file is small, so a large cover file is needed to hide a substantial amount of data; and once data are hidden in an image or audio file, any lossy compression destroys the embedded data. It seems that such an image sh
