One failing of an encryption system occurs if we never let theencrypted value of a letter be thesame as the original, especially if a letter always encodes to thesame value. Let’s see how we canexploit these weaknesses. Let’s assume that we know that the wordWHICH is somewhere in theintercepted message. If we received the following transmission,what are the encrypted values (i.e., givethe mappings) of the letters W, H, I, C (i.e., W -> ?, H ->?, I -> ?, and C -> ?)5ITVRCD7CVR5TVPV75IO
To test your detective skills, what is the exact originalmessage that was sent (if there is are blanks in themessage, please denote with an underscore)?Hint: It’s a simple cipher ... look for a unique pattern in WHICHand because you are told that a characternever encodes to itself and that a character always encodes to thesame value, you can exploit this tofind out where WHICH appears in the message.
