Im trying to understand how TTH works, but have a question.
Let's take this example:
A B C D E F G H I J K L M N O P
Then we add each column mod 26 and add the result to the running total, mod 26, in this example, the running total is (24,2,6,10)
Round 2: Using the matrix from round 1, rotate the first row left by 1, second row left by 2, third row left by 3, and reverse the order of the fourth row. In our example.
B C D A G H E F L I J K P O N M
Now , add each column mod 26 and the result to the running total. The new running total is (5,7,9.11).
This running total is now the input into the first round of the compression function for the next block of text. After the final block is processed, convert the final running total to letters. For example. If the message is
ABCDEFGHIJKLMNOP, then the hash is
So, my question is how to we use the hash FHJI for the next block of data if it exist?
Assume our data was
How will I use the runing total produced by first block of data with another, following block?
