# False Bottom: A deniable encryption scheme
|
|
False Bottom is a [deniable encryption](https://en.wikipedia.org/wiki/Deniable_encryption) scheme.
|
|
The name “False-Bottom” alludes to well-known equipment of stage magicians, who have boxes that can be opened to appear empty or with something inside, hidden under a false bottom. This scheme is designed for the same effect, hence the name.
|
|
As such, unlike traditional encryption algorithms, False Bottom allows for the encryption and decryption of multiple messages to and from a single ciphertext.
|
|
Each addition returns a message specific key which can only be used to decrypt the correspoding message added.
