arnezami,

I have a few problems with this method. Although at first I thought that this would be the way to do it and finally crack the puzzle, I am beginning to wonder if we're walking down a false path.

My reasoning is that we knwo that Professor Sente Kiteway was involved, based on the reply from Garnet. So, we must assume that at least one of those three words woud appear in the coded text, or at least something linking to him. So far, testing on all the methods, none of them have given anything other than garbled rubbish.

I am at a loss where to proceed, but still, won't give up as I'm sure the solution is around the corner!

I think a bigger problem is everything on this card that in my opinion isn't being addressed satisfactorily by this method. I still don't think the two sets of disappearing texts are there only to go away and be ignored. They reappear in the cold, after all. Furthermore, I think the whispered statement is more than a direction to ignore the coldtext. Much more, in fact.

I think this method may be used in solving the card, but in way that would better incorporate the coldtext and the whispered hint.

But while you're trying words, ACADEMY might be worthwhile, if it hasn't been tried already. It might implicate SENTE without directly mentioning him.

There are still quite a lot of possibilies I believe. And technically we really don't know what is in the messages. But yeah this could of course be the wrong path enterily. No way to be sure. Wink

I think I will add some more possible ciphertext arrangements like beginning at the outer edges and going inwards (or the other way around). And some others.

What do you mean by "testing on all the methods"? Which ones are you referring to?

Unfortunately i don't have the puzzlecard yet, so i can't see a full close up of the puzzle, only the posted scans/pictures which aren't high enough resolution.

There are numerous ways the key could be hidden, but the main options would be:

in the whispered phrase "If entropy wins, outward looks should leave you cold."
within the 10 disappearing letters
in the order of the cards
or built into the code itself

the only other method without being supplied the key is the A-B route.

We must assume that Garnet knew no other information than we have been supplied (so this would ignore the suited cards on other puzzle cards). We must also assume that the cards were in the standard pack order as he said they were untouched.

the joker with the star undoubtedly points to the solitaire cipher as marking one of the jokers is needed to distinguish between the two.

The cryptic clue given with the whispered message, in my opinion, indicates that the disappearing letters should be ignored. This gives us just the one option of trying different words in a 54/54 split (or other - although this seems more likely with the 54 cards per deck and two messages being needed).

Anyway, i digress... and now i've forgotten my point Sad

****
arne, by testing all methods, i mean using all the relevant words (SENTE, KITEWAY, PROFESSOR, etc) in all the ciphertext styles you implemented in your program.

Added 4 more ciphertext arrangements. inwards/outwards per 1 or 5.

There are probably more to think of. you can also put the ciphertexts in manually btw.

Don't know if already been mensioned but couldn't it be some variation of a keyphrase cipher, we have been given a phrase that we can use.

If that is the case we may need to break the phrase like so

I F E N T
R O P Y W
I N S O U
T W A R D
L O O K S
S H O U L
D L E A V
E Y O U C
O L D

(like the playfair cipher) http://en.wikipedia.org/wiki/Playfair_cipher

Just an idea

Or like this,

I F E N T
R O P Y W
S U A D L
K H V C B
G J M X Z

but I'm sure we've covered it before. I don't know if I've seen it since page two of the first Shuffled thread. No harm in trying again I suppose.

I like arnezami's idea of trying to identify words in the ciphertext. Actually, while trying certain likely words, I came across this anomoly...

Code:

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXSENTEKITEWAYCREATEDTHEWORM
BUHVFWPDBERKQFNSSPVHXWUWFAMTPJTPSDKWESFCPQYVNREFCMFYYACPQEFJHHTPIAXBWNPNGQRDMUXDGLPSGTFHQNLKHBMXJNCLCEBPYFNTYHZKBIOGJXALDJGADVZ
                                                                                                             HZKBIOGJ
                                                                                                           YNGYJBIOGI

Encode line 1 with the SolitaireCipher (using the standard bridge order), which yeilds line 2. Look at the eight letters starting at position 110, given again on line 3. These nearly match most of the ciphertext "YNGYJBIOGI" (letters 51-60 on the card), with only the leftmost three and rightmost one shifted up one letter (rot-1).

It may be possible to work backwards to find out what the deck order should be when we reach this point in the message. Alternately, we could consider that the groups of five (or maybe groups of four) ciphertext letters have themselves been shuffled. (Note that line 1 is 127 letters).

I emailed Mr.Schneier about how to do a (A+K)-B+K thing.

My explanation is on the back pages of Cryptonomicon.

I guess who ever has Cryptomoicon will check it out???

just a thought (actually quite a frightening one as it means me reworking a load of stuff by hand Wink)

the applets on the site uses the deck as always being 1-54 at the start

If the deck order in the pack is relevant - then we will need to have a starting deck of 53 54 14-26 1-13 27-52 before using and pass phrase on the deck

can anyone amend the code (its on the site) to change the starting deck accordingly?

This may be worth doing to help automate the process more

[EDIT] I could host it on the 13th site [/EDIT]

[EDIT 2] am sorting something [/EDIT 2]

PS i so cant beleive i only thought of this

I modified the perl script to accept an parameter after the passphrase in the form of JAJBDICLHESP and have been trying it with many passphrases and attempts.

So for every passphrase I try, I am running the perl script with the standard deck order, the motor deck order, joker a first, motor deck order joker b first and many permutations of the 128 characters on the card, as well as both encrypts and decrypts.

If you are interested, download the modified perl script here. I don't write a lot of code, so my changes are probably a kludge, and perl is too slow for any kind of sustained decrypts.

So this is how you can run it in a UNIX-like environment:
Code:

echo "EODMF XRUTH FHURG IFULP"|./sol-suit-manual.pl -d 'opensesame' JAJBDICLHESP


It sets the deck order (in the case above to motor deck order, joker a first) prior to the phrase keying the deck.

arnezami if I understand your program, submit a word or phrase pick your options and see if a word or part of a word is out putted.

Yes. The program uses the formula (A+K)-(B+K) = A-B (or A-B exploit for short) to let you guess part of one message so it can decrypt part of the other message. In other words: you give it a word then the program first assumes its part of message A and will then calculate B. And it tries your word at every position in message A. Then it assumes your word is in B and calculates A. And it does so on every position in B. If it results in any word or partial word anywhere at all (of say 4-5 characters long) it could be interesting.

Read here for a better explanation.

The biggest problem is we don't know where message A ends and where message B begins. Or how they are arranged on the card. While this is crucial for this technique to work. In fact we don't even know if the are two messages (A and B) on it that are encrypted with the same key. But that is the assumption when using this A-B technique. Wink
