Stealth Ciphers

About the Book

The book discusses the encryption process that modifies information in a way that makes original data unreadable until the exact same process is reversed.

The book takes into account the historical uses of ciphers from the ancient to the modern times. It guides the reader through the fundamental concepts of algorithms, running time, efficiency and most of the important encryption techniques and standards as well as the concept of the use of keys in cryptography.

The book leads the reader gradually to the most significant open mathematical questions, which up to this date have not been answered and to the alternatives as in quantum computing to solve such problems. The answers for these unsolved problems would give us a distinct advantage in the current digital warfare of the 21st Century and for future generations.

This is an excellent, up-to-date and easy-to-use text on classical and modern ciphers that is intended for undergraduates in computer science and information science. The book contains many examples and diagrams. Whenever appropriate, program codes are included to facilitate learning.
