This problem explores the use of a one-time pad version of the Vigenere cipher. In this scheme, the key is a stream of random numbers between 0 and 26. For example, if the key is 3195, then the first letter of plaintext is encrypted with a shift of 3 letters, the second with a shift of 19 letters, and so on. (a) Encrypt the plaintext "cryptography" with the key stream 319520812 1023611137 . (15 points) (b) Using the ciphertext produced in part a, find a key so that the ciphertext deerypts to plaintext "kennesawuniv". (15 points)
