Hail Cipher

48 posts in this topic

lol I for one would appreciate a hint... or maybe not.. as that would probably just mock my knowledge even more. :cry: I am going to read some cryptography books.

Maybe ALAS BABYLON, is the key that was used to encypher the second part. A Polyalphabetic substitution cypher perhaps?

it looks abit like a shortwave number station transmission.

it could be using ALAS BABYLON as a key for a vigenere ciper too. but, i don't know (lol, i just read the post above mine :roll: ) i think you need to look for words/letters which are encrypted with the same part of the key to decrypt vigenere cipers. just any repartition, in the encrypted text <_<

lol

Alas, November has 30 days. To keep things consistent, I guess we should just pretend tomorrow (Dec. 1) is the 31st and end the challenge at 23:59 EST.

i can't find the book! and i'm in a really bad mood now because of others things :angry: lol

anyway, i think the key is the first 19 letters on page 420 using a vigenere cipher :unsure:

the whole nov. 31st thing kinda threw me off. making me believe more that it was impossible because the date in which it ended did not exist :P . im really late but im going to still give this a try

so has anyone got the first line of page 420?

It doesn't have that many pages...

Iceni was right about the inspiration being from shortwave numbers stations. I wanted to try to come up with a foolproof use of the number stations methods (as I figure one use of them to be), and ideas like the ones put forth by Project Evil with Mein Fraulein. Like some others, I think many of those shortwave transmissions rely on books as the key given on a one time pad. I wanted to try implementing a cipher that had no reliance on computers and could be passed with ease. So I figured I would try this out. It seems to work well. Even when given the nook title, no one thought of the use. In a real situation, the books title would be a complete mystery known only to the intended recipient who was notified on a prior date orally or via one time pad. That would make it practically unbreakable, if not completely so, as long as the key (the chosen book) was unknown.

The Caesar Cipher of the title was intended to be easy. So that was obviously "Alas, Babylon".

The format I had is known, even though it's not the most common.

420 420 420 sounds like a possible recipients identifying number followed by either random, or 1-10 linear readings. This goes on for a long time sometimes, sometimes as short as 20 seconds or so. Grupo 019 Grupo 019 traslates into "group 19" or group of 19. The 19 groups that follow are:

249 12 | 066 29 | 263 19 | 124 07 | 159 05 | 043 05 | 256 16 | 127 36 | 285 21 | 130 12 | 044 132 | 104 03 | 272 04 | 047 127 | 130 12 | 130 11 | 249 12 | 259 57 | 108 38 |

Those are in a page:word format, so the first is page 249 word 12, the second page 66 word 29, etc,. The text was:

To survive be prepared to have radio communications salt and cans in the cupboard and guns to keep defense.

Plan a book to be used in advance, and give the title to your partners/brothers/confidants . After that you can pass a code over radio, in classifieds, on Craigslist or other social sites (ala Mein Fraulein), through postal mail, disposable email, on a billboard or any other public method, with confidence it is supremely secure.

If anyone wants to hazard an educated guess on the chances of this being broken without the books title, I would be interested in that.

I was on the right track kinda. I didn't have access to the book but had read a web page about it and how they used the words Alas Babylon as code words for emergency. I had figured there was more to this puzzle than just the book it self and looked a little to far into things and figured the cipher was really based on the bible. So I spent a few hours trying to match the numbers up in different combinations of letters and words from the bible Revelations chapter 18 verse 10 and the following. So in the end I came up with nothing. I think this is a pretty good method as long as you the book you're using as a key is kept secret , you change them at random, and never use the same one twice. Good challenge and keep up the good work!

BTW Like the sig. our countrymen do need to wake up and realize freedom is more important than anything material!

Well, there are several editions of the book

0060931396.01._BO2,204,203,200_PIsitb-dp-500-arrow,TopRight,45,-64_AA240_SH20_OU01_SCLZZZZZZZ_.jpg0060741872.01._BO2,204,203,200_PIsitb-dp-500-arrow,TopRight,45,-64_AA240_SH20_OU01_SCLZZZZZZZ_.jpgB000E1DCGE.01-A1KTD478YXKD7V._AA240_SCLZZZZZZZ_V41605518_.jpg0553115022.01-A1QG3W3TZ7ACUQ._AA240_SCLZZZZZZZ_.jpg

And i guess there are several different formats of the book, which means that even if someone figured it out, he'd have to to search through all of the books variations to make a senseful sentance ... that is ofcource if he doesnt know the right book edition :)

The best thing about this method is it doesn't even have to be books it could be anything with words or letters on it which would make it almost impossible to figure out without having the information from someone within the circle intended recipients.

Where The Action Is, good point on the multiple editions. I don't know if different printings would be laid out differently. The one reason I chose that book was that the title itself "Alas, Babylon" was a codephrase. I thought maybe if anyone had read that particular book, they may put two and two together. I knew some assistance would be needed, but didn't want to give to much.

Having a consistent key would be crucial. I hadn't even thought of it, so thank you. I'll have to revise the plan.

You should point out the year of the printing you used, nothing more.

Despite the different printing problem, your idea is great :)

Awesome idea, but what does the "had to break protocol into a 3/3 twice" mean?

It was just another minor assist/hint. You'll see the page:word part is in a xxx xx format for all but 2, when I had to use xxx xxx since the word I wanted was on a page < 100 and was word 100 or greater on that page. I just added a zero there to pad the front.

Numbers stations would use a strict 3/2 or 5 number block throughout or something, most times.

pretty cool, i suppose the only weakness is keeping the key a secret. what you can do is tell the person the key will be the first 9 letters of the 10th page of a certain publication sometime in the future, that way you don't need to send it. but, there's can be confusion that way if you pick a newspaper with different editions throughout the day lol

does that make sense? that will keep you from sending the key, but you still have to send the message, but the message is nothing without the key :huh:

You could maybe create a cipher for the ISBN number of the book in use.

Most intriguing... I still think about this thread as one of the most inspirational. I love codes, I love mind games and I love a challenge... everything that makes me a hacker is within these posts.

Thank jebus for binrev and all hail the almighty cipher :borg:

I think I am going to read this book <_<
