The cryptogram decoding using encoded
Answer to Problem 59E
The final message is
Explanation of Solution
Given information:
Formula used:
Matrix multiplication is used.
Calculation:
To decode the following cryptogram:
8 21 -15 -10 -13 -13 5 10 5 25 5 19 -1 6 20 40 -18 -18 1 16
Using the some unknown decoding matrix
Dividing them into
The last word of the message is _RON.
So,
The first two letters of the last word are _ & R. So,
And
Also ,
The last two letters of the last word are 0 & N. So,
Using
Thus, get
Thus, get
Now to get the uncoded row matrices,
Coded matrix Decoding matrix Uncoded Matrix
We get the following uncoded row matrices,
Splitting them we get,
13 5 5 20 0 13 5 0 20 15 14 9 7 8 20 0
When the numbers are converted to the alphabets they are assigned to we get the message
Using the last word of the message, the final message is
Conclusion:
The final message is
