Most of us associate cryptography with the military, war, and secret agents. And, indeed, those areas have seen extensive use of cryptography. In World War II, for example, a great deal of effort was expended to create systems so that the high command could communicate with generals in the field over

Codes operated by substituting according to a large codebook which linked a random string of characters or numbers to a word or phrase. For example, "UQJHSE" could be the code for "Proceed to the following coordinates." When using a cipher the original information is known as plaintext, and the encrypted form as ciphertext. The ciphertext ...

To implement a book cipher, each word in the secret message would be replaced with a number which represents the same word in the book. For example, if the word "attack" appeared in the book as word number 713, then "attack" would be replaced with this number. The result would be an encoded message that looked something like this.

BOOK CIPHER, RUNNING KEY CIPHER, VIC CIPHER AND SECOM CIPHER A book cipher is a cipher in which the key is some aspect of a book or other piece of text; books being common and widely available in modern times, users of book ciphers take the position that the details of the key is sufficiently well hidden from attackers in practice.
