Editing Running key cipher (section)

=== Ciphertext appearing to be plaintext ===

Traditional ciphertext appears to be quite different from plaintext. To address this problem, one variant outputs "plaintext" words instead of "plaintext" letters as the ciphertext output.  This is done by creating an "alphabet" of words (in practice multiple words can correspond to each ciphertext output character).  The result is a ciphertext output which looks like a long sequence of plaintext words (the process can be nested).  Theoretically, this is no different from using standard ciphertext characters as output.  However, plaintext-looking ciphertext may result in a "human in the loop" to try to mistakenly interpret it as decoded plaintext.

An example would be BDA (Berkhoff deflater algorithm){{Citation needed|reason=Can't find any explanation about this out there|date=October 2019}}, each ciphertext output character has at least one noun, verb, adjective and adverb associated with it. (E.g. (at least) one of each for every [[ASCII]] character).  Grammatically plausible sentences are generated as ciphertext output.  Decryption requires mapping the words back to ASCII, and then decrypting the characters to the real plaintext using the running key. Nested-BDA will run the output through the reencryption process several times, producing several layers of "plaintext-looking" ciphertext - each one potentially requiring "human-in-the-loop" to try to interpret its non-existent [[semantic]] meaning.
