A cipher machine is a mechanical device for encoding and decoding messages.
The cipher "0" is commonly known as the "null cipher" and the "zero cipher." A null cipher encodes a message by hiding it within a larger body of text, often using specific letters or words to reveal the intended message, while the zero cipher is a more general term that can refer to any encoding that represents information with no visible changes in a certain context.

unconditional security no matter how much computer power or time is available, the cipher cannot be broken since the ciphertext provides insufficient information to uniquely determine the corresponding plaintext computational security given limited computing resources (eg time needed for calculations is greater than age of universe), the cipher cannot be broken

The BAUDOT code is made from a cipher. The cipher that does this is also known as a Bacon cipher.

A transposition cipher involves scrambling the letters in a message. The strengths of this are that there is less correspondence between characters, as there is in a substitution cipher, and that it tends to reduce redundancy.
