Question: one failing of an encryption system occurs if a letter...
One failing of an encryption system occurs if a letter (or number) always encodes to the same value. Let’s see how we can exploit these weaknesses. Let’s assume that we know that the word SECRET is in an intercepted message. What are the encrypted values (i.e., give the mappings) of the letters S, E, R, C, T (i.e., S -> ?, E -> C, R -> ?, C -> ?, and T -> ?) for the following encrypted message: MHIL75K7MTF7LL397V
To test your detective skills, what is the exact original message?
