The ciphertext ’GOBBWZP’ was encrypted using the affine function. If the first two alphabets were fr. Find the plaintext
Homework Answers
Hey
It is easy to see how each character in the plaintext is replaced with the corresponding letter in the cipher alphabet. Decryption is just as easy, by going from the cipher alphabet back to the plain alphabet.
plain alphabet : abcdefghijklmnopqrstuvwxyz cipher alphabet: phqgiumeaylnofdxjkrcvstzwb
The Cipher text is FRBBWZP.
The plain text is NSZZYXA.
Thank You

Assume that Alice sends a message of 640 bits encrypted using DES to Bob and that the 65th bit of the ciphertext is flipped during transmission. How many blocks of the plaintext at the Bob’s side are affected if the message is encrypted under ECB, CBC, 8-bit CFB, 8-bit OFB, and CTR modes, respectively?

Using Python; Caesar part of the homework: Write c_encrypt() and c_decrypt(), both of which take two arguments, the first one a string and the second one an integer key. Both should return a string. Vigenère part of the homework: Write vig_encrypt() and vig_decrypt() functions. Each takes two strings as inputs, with the first being the plaintext/ciphertext, and the second being the key. Both should be calling functions you wrote earlier to help make the work easier. The key will be...
