The Mathematics Of Secrets (eBook)
Cryptography From Caesar Ciphers To Digital Encryption
de Joshua Holden
Sobre o livro
The Mathematics of Secrets takes readers on a fascinating tour of the mathematics behind cryptographythe science of sending secret messages. Using a wide range of historical anecdotes and real-world examples, Joshua Holden shows how mathematical principles underpin the ways that different codes and ciphers work. He focuses on both code making and code breaking and discusses most of the ancient and modern ciphers that are currently known. He begins by looking at substitution ciphers, and then discusses how to introduce flexibility and additional notation. Holden goes on to explore polyalphabetic substitution ciphers, transposition ciphers, connections between ciphers and computer encryption, stream ciphers, public-key ciphers, and ciphers involving exponentiation. He concludes by looking at the future of ciphers and where cryptography might be headed.The Mathematics of Secretsreveals the mathematics working stealthily in the science of coded messages.
