I have devised an uncrackable substitution cypher codeI think...no doubt others have come on here with the same message. It does not use computers by the way. But how to test it?? Would you need thousands of coded messages? I am new to this forum so all responses welcome, thanks. #2 20100124 05:33:18

Re: I have devised an uncrackable substitution cypher codeI truly believe it is uncrackable because you cannot tell which letters are the message and which are fillers, which have been selected from a list that takes into account letter frequencies. It is a 26 letter wheel on top of a 26 letter wheel. But you don't know the wheel start point, or how it rotates, or which letters in the given block are the message. Were I to send a second message, the letters forming the message would be differently located, of course. How can it be cracked? from a theoretical point of view? Since you don't even know how many letters comprise the message. The wheel start point and where the message starts, and the number of filler letters between message letters is all stated within the block so the recipient can decode it quickly and easily. Comments, please. #9 20100211 02:27:51

Re: I have devised an uncrackable substitution cypher codeHmm... I think I remember talking to a Cambridge undergrad about an uncrackable cipher, and replied that it was indeed possible to do so. Can't remember how, though. #11 20100211 14:24:14

Re: I have devised an uncrackable substitution cypher codein the enigma codes i believe every letter in the code was used in the message, and in sequence, so ANJERVSKH meant something, so A = A or B or C.......or Z and N=A thru Z and J=A thru Z you look at all permutations, eg 26 to the power 9, not hard for a computer.... #14 20100212 14:36:21
Re: I have devised an uncrackable substitution cypher codeHi bob;
Back in the days when Alan Turing cracked it there weren't any computers, he had to invent colossus. The first enigma machine was found by the Poles whose mathematicians paved the way for cracking it. In mathematics, you don't understand things. You just get used to them.

Re: I have devised an uncrackable substitution cypher codethere are 500 letters in the coded text, you do not know how many of these comprise the actual message, you do not know the direction of the text as stated in an earlier post. You therefore need to take any 499 letters, ie 500C499 = 500C1 = 500 and then put them in every possible order = factorial 500 AND for each order, any letter can equal any of 26 letters according to the coding system I have used, which gives factorial 500 multiplied by 26 to the power 99 #16 20100214 02:43:27

Re: I have devised an uncrackable substitution cypher code
Initially difficult, but I was shown how to use it. Incredibly slow encrypting a message and it felt very 'bulky'  but it was definitely a worthwhile experience. If I remember correctly, the arrangement is not the usual "QWERTY" setup, since the German language has different frequency letters; arrangement is "QWERTZUIO" (1st row), "ASDFGHJK" (2nd row), and "PYXCVBNML" (3rd row). However, though the enigma machine was difficult to crack, and initially very successful for the Germans  the British did eventually crack the code. They always ended their coded messages with "Heil Hitler", and, not only that, but they became rather careless with their alteration of the machine's three wheels; when you encrypt a code, you spin the wheels several times such that the order is completely different. Instead, the Germans decided to turn only the first wheel by 1 unit, meaning a pattern emerged in the enigma machine's code. They weren't particularly careful with the code configuration either; they published the new configurations monthly, which were accessible to the public  which the British later discovered. It was the carelessness of the Germans that led to their codes being decrypted so quickly. #18 20100214 14:15:52

Re: I have devised an uncrackable substitution cypher codeHi;
No, it is just a hypothetical. The point is this. In constructing your encoding method you have used methods that have made a diificult code to crack. Those same methods have made it mathematically difficult to verify that it is uncrackable. Therefore you have no certainty that it is uncrackable. It might fall to the first attempt someone makes on it, I can't say. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: I have devised an uncrackable substitution cypher codeit is a 26 letter alphabet wheel in random order rotating on another such one. It may sometimes advance with each new letter to code. As mentioned earlier, you do not know, in the block I have given you, which is the start letter or end letter, and you do not know how many dummy letters are between the start letter and the end letter, and I would not be daft enough to use the same number of dummy letters between each message letter. I may go left to right, right to left, up from left, up from right, down from left, down from right or a complicated diagonal pattern. Pages: 1 2
