The use of secret communications by means of coded messages has been
a practice throughout ancient and modern history. In recent wars,
messages were sent in alphabet cipher to ensure that the messages would
not be read if they fell into enemy hands. This type of cipher is still
used today. Codes and ciphers were used by generals, kings and even
presidents to plan battles and to transmit important information. George
Washington established a spy system to report on the British forces and
their movements. To send such important information, each spy had a code
book that contained code numbers, each number representing a specific word.
A written coded message consisting of a series of numbers would be used to
transmit the secret intelligence gathered.For many, the ideas of cryptography and cryptoanalysis have been fascinating areas for study and recreation. The whole point of cryptography is to solve problems. The type of problems that cryptography solves revolve around secrecy, security and privacy. The Advanced Military Crytography Book presents various basic cryptographic principles and the fundamentals of secret communication by describing and illustrating the traditional cryptographic techniques designed before the computer age. Computer programmers will enjoy these algorithms and methods.
