Beginning with one of the oldest and simplest mathematical systems used by Julius Caesar, this book goes on building more complicated schemes ultimately ending with the RSA cipher which was developed by the MIT computer scientists. It is one of the ciphers that is used to provide security for the Internet. Also, for each system developed in the book, the author has described both the enciphering and deciphering processes. The study of integers and their properties has been presented in an exciting manner relevant to the modern context of cryptology. Most of the books on cipher begin with a mathematical topic whereas the beauty of this book is that it begins with a cipher and mathematics has been developed as and when needed; the applications motivate the mathematics. For all the ciphers introduced in the book, JavaScript programs are available from the webpage for this book which run on the user's computer. (Zentralblatt)
