Consider a modified autokey cipher which uses a keyword instead of a single key and the rest of keys stream is derived from the beginning of the plaintext as shown in the example below. You are required to perform a cryptanalysis attack, specifically a known plaintext attack, in order to find the key used to encrypt the message pair assigned to you Notes: . . . You can find the message pair assigned to you in the below tables. You should find a smart way to crack it (Brute-force attack it NOT allowed) Show your work in detail explaining the process you followed to crack the key HINT: Keyword length is 4-5 characters. Plaintext "do not attack Plaintext (P)do notata c k P in integers 3 14 13 4 190 19 190 10 Key C in integers 2 73 22 14 671923 How can I find the key??
