Hello,

The following text has been encrypted using a numerical technique. A student did it so it is not highly sophisticated. The text is:

434548466365686672635857000000007375787663646866535458565274897772637957000000001213878622237776323367664243575600000000434548465355394755566866434548465355394755566866636459686465686700000000434548465355585763653947737468667263496700000000121387862223777632336766424357560000000033353836434548475355585663645957726339586372583700000000434548465354585763656866000000003335383653555856625348474233595752423958425258370000000535558575254000000001213878622237776323367664243575600000000636568665355585673747877725459576272696872624958000000006365686753554846434558577263394700000000737478776364686653545857747549676465796854500000000333538373536484653555857555646456365787773754938757600000000333578765355585663653837434537367375



The only available hint is: "eight(8)".

If any of you can provide any help or actually decipher it please let me know ! Besides it is a nice challenge and am currently also working on it.

Thank you,

Baroudeh.

I don´t know... could be anything... I followed the hint separating in sets of 8 elements, and everu set ends with a 2 length number becuse you posted the cyphered text with separated parts by space

In fact, it is improbable that every set of 8 elements represents a word, since there is to many words with exactly 8 letters, but we don't know if every number with 2 elements representes a letter, since the alphabet has only 26 letters and there is numbers such like 96. Could be a cypher such that more than one number represents a letter. Some sets of numbers are most common:

Hi,
are you sure this is right? Near the beginning of the 5th row, there are seven zeroes instead of eight. Also, if you insert an extra zero there, the total number of digits (whitespace excluded) is still one less of a multiple of eight, as if another digit was missing.

It might be helpful to state other assumptions that you take for granted between you and your student, such as in which language is the text.

Well the text is written in english if that can help.

I think the numbers represents syllables

That maybe true... but i don't thing he would give such a hint... i think the eight hint is a litte more complicated than that... Do you have another theory regarding the hint?

Interesting set of numbers...

My observations, don't know if they will help or not:

0
There are 119 zeros. 14 sets of 8, 1 set of 7 (someone questioned if this was a mistake?)

1
There are only 6 ones. They follow a very strange pattern, only appearing in the sequence "1213" at the end of certain sets of 0's

2
There are 37 twos. there are never just 2 consecutive twos, without a third. And this happens only three times.

3
There are 98. These seem to be very well spread out. There are never more than 3 in a row.

4
There are 70. There are never two in a row... but follow somewhat of a curious patter usually 4, number, 4 number, 4, number... like the beginning 4345484.. this same pattern happens 6 times.

5
The most common. There are 125. These seem to be very well spread out. There are never more than 3 in a row.

6
There are 110. These seem to be very well spread out. There are never more than 3 in a row -- but this happens only once.

7
There are 87 sevens. These seem to be very well spread out. There are never more than 3 in a row.

8
The clue! There are 56 of them. There are never more than one of them, like the 4s.

9
There are 18 nines. Again there are never more than 1 of them in a row.

That's all I have.

if the number representes syllabes, one of then must be "a", and other "the", and other "that", most common in english

It might be helpful to state other assumptions that you take for granted between you and your student, such as in which language is the text.

I second this. I really think there is something odd, if not wrong here. Can you double check with your student that this is correct?

separated by zeros sequences, we see some patherns, but I cannot say anything better than conjectures

Separate by zero sequences, but when you get to the sequence with only 7 zeros isolate the 5 and keep going...

Honestly, it is a gut feeling.
I think this whole thing amounts to one sentence with the sequences of zeros are the spaces between words.
 
  • #16
I think this text is a poem or lyrics of a song, and the length of the zeros string denote the numbers of words in the sentence... the strucute suggest this conjecture, sentences repeated, combination of numbers that suggest rhymes, etc

if so then
43 45 48 46 53 55 39 47 55 56 68 66 43 45 48 46 53 55 39 47 55 56 68 66 63 64 59 68 64 65 68 67

must be a word, and if this is a word and the hint is about sillables, every set of 8 numbers denote a sillable, and the owrd above has 4 sillables


43 45 48 46 53 55 39 47 55 56 68 66 43 45 48 46 53 55 39 47 55 56 68 66 63 64 59 68 64 65 68 67

but the problem is: we don't see the sillables like these ones repeated in the text, and it is a little bit strange a text without ant sillable repeated

in the other hand, there are 724 numbers, and 8 do not divides 724

I count 726 digits. My speculation is that there is a missing zero as indicated before, and another missing digit, possibly within the sequence 7374787763646866535458577475496764657968545 (end of 6th row and beginning of the 7th), which is the only sequence between zeros with an odd number of digits (43). The extra zero and the extra digit would add up to 728, which is divisible by 8.

P.S.: If (big if) the total digits were 728, then it adds evidence to the idea that every 8 digits compose (somehow) a letter, the 8 zeroes being spaces between words. Words coming out this way have a reasonable average length. My (further) speculation is that the first and 8th words are the word "THE", 43454846 standing for the letter "T", but the code is position-dependent: the combination of 8 digits *and* the letter position (1st, 2nd, 3rd, 4th... letter of the text) would combine to decode a letter.

These is the numbers used in the chypher considering:

1 - the chypher consists in 2-lenght numbers

2 - the cyphered text is not complete, and I fill the blanks as dodo and diffy suggest, but the alone 5 in the 14-th row I cannot say for sure what is the missing digit... my guess is that the missing digit is an 8, being 58 the last element in the 14-th row

So we have the table below

32 33 35 36 37 38 39

42 43 45 46 47 48 49

62 63 64 65 66 67 68

86 87 89

Something I noted (though I haven't made anything useful out of it) is that base 8 might play a role.

In what follows, consider only the 'words' - the strings of digits between zeroes (that is, exclude zeroes from this consideration, and restart your 'position counter' to 1 at the beginning of each 'word').

Now, if you take alternative digits (i.e. the digits in odd positions vs. the digits in even positions), you'll notice that they are in base 8, offset 12121212... That is, all digits in odd positions are in the range 1-8. while all digits in even positions are in the range 2-9.

Subtract 1 from digits in odd positions, and 2 from digits in even positions, and they will all be octal.

could be a nice hint, indeed, but the problem is: there is no 8 and 9 as symbols in the base 8, only 0,1,2,3,4,5,6,7... so, perhaps we should convert all numbers to the base 8, considering that those numbers are in base 10

8 becomes 10
9 becomes 11

I didin't find any material regarding the frequency of syllables, digraphs or trigraphs, so it's a little bit difficult go any further.

I was considering if the text is chiphered with another kind of chiper, like the DES kind, RAS, or something like that... I am not an expert, far away of that, but my guess is: because of the patherns is very unlike a strong chiper like those generates patherns like these, so I still think that the chiper is some kind of more simple substitution chiper concerning syllables, digraphs or trigraphs

Since this has been kicked around without it being broken, maybe (Mr) Barovdeh could give us more infro on the level of education of the student and any relevant course of study.

Just something to kick around when one is not busy. Or could this be something to worry over, like a cipher to start some event to happen around the world. It is not fair that they chose a student to write this! Egads, look at all those who are reading this cipher even now.

#V#VW#V"V"VaaLLLL#V#a8V#V#a8V"b-W#V#W#a"VaLLLL#V#W#V"ab W#V"W#V#V#VWabW#WLLLL#V#V"Wabb#W#V#Wa"W"V"W-a-b-#W8V#W8A#W#b8#V#V#W#L#

not much help but I think the cypher might interlace irrelevant data in the even positions to throw would be decoders off the track.

You know, one-time-pads and RSA are "not highly sophisticated" either.

A numerical technique for decrypting encrypted text is a method that uses mathematical operations and algorithms to convert the encrypted text back into its original form.

2. How does a numerical technique work for decrypting encrypted text?

A numerical technique works by analyzing the patterns and structure of the encrypted text and using mathematical operations to reverse the encryption process and reveal the original message.

3. Is a numerical technique the most effective way to decrypt encrypted text?

It depends on the type of encryption used. In some cases, a numerical technique may be the most effective way to decrypt encrypted text, while in other cases, other techniques such as brute force or frequency analysis may be more effective.

4. Can any type of encrypted text be decrypted using a numerical technique?

No, not all types of encrypted text can be decrypted using a numerical technique. Some encryption methods are specifically designed to be resistant to numerical techniques and require more complex decryption methods.

5. Are there any limitations or drawbacks to using a numerical technique for decrypting encrypted text?

One limitation of using a numerical technique for decrypting encrypted text is that it may require a lot of computational power and time, especially for longer and more complex messages. Additionally, if the encryption method used is strong enough, a numerical technique may not be able to decrypt the text at all.
