I don’t think* so but this is an interesting cipher.
You begin by transcribing the message into Morse Code.
And then… (from G. Worley)
When written on paper, letters are separated by a divider (often written `x') and words by two dividers. For example, if Alice wanted to send Bob the message "I love you." she would tap over the telegraph: Pt: I love you. Et: ..xx.-..x---x...-x.xx-.--x---x..-xx.-.-.- Each digit from 0 to 9 represents a dit, dah, or divider. The digits are permuted over a sequence of dits, dahs, and dividers specified by the protocol.
3 4 7 0 2 6 8 1 5 9
. . . . - - - x x x
So, to encode Alice's message from earlier using this key:
The specific digit used should be picked at random to make it harder for the pen
and paper cryptanalyst, especially since it doesn't matter to Alice and Bob
which specific digit is used so long as it maps to the right Morse Code.
The easiest way to start cracking Pollux is by trying to find dividers: they
must occur every 2nd, 3rd, 4th, or 5th digit (every 6th or 7th if there's
punctuation). Once you find the dividers you'll soon be able to find the dits
and dahs and, from there, decode the text. Thus, you should only use this for
messages between 155 and 385 characters.
The keyspace of this cipher is:
------ = 4,200
Which, as you might know, is small enough to crack in a few minutes or less. A
variation would be to expand the keyspace by mapping dits, dahs, and dividers to
more characters, like letters of the alphabet. In English that would be:
------ = 75,957,810,500
Which is still crackable in a very short amount of time, so don't go encrypting
your most precious secrets with it.
You might also change this by using digraphs. There are nine Morse Code
.. .- .x -. -- -x x. x- xx
Cipher Clerk offers a handy program to apply Pollux decryption.
Using the standard setup described by Worley I didn’t retrieve any plaintext. I fiddled with the assignations and still couldn’t get anything.
*This is because Pollux works by encrypting to numbers and decryption would need numbers as input.
GIGO is the reason it didn’t work.
