In the transposition stage, plaintext would be written into a “cage” or “box” (a shape on a piece of paper) by the cipher clerk. The bigram tables then were used to substitute the pairs of letters [23]. The structure of a codebook has a code, its brief description, its full ...
and to transform a plain-language signal into a cipher text, all the operator had to do was consult the book of keys, select the key for the time of the day, the day of the month, and the month of the quarter, plug in accordingly, and type the signal out on the left-hand typewri...

The field of modern cryptography, which is essential for securing digital communications today, has roots in the non-tech codes of the past. Many of the principles used in ancient codes, such as substitution and transposition, are still relevant in modern cryptographic algorithms. The evolution of...
