(multiplicative one-time pad). We may also define a "multiplication mod " variation of the one-time pad. This is a cipher, defined over where, where p is a prime. Encryption and decryption are defined as follows: Here, denotes the multiplicative inverse of modulo. a) Verify the correctness property for this cipher [5 pts] b) Prove that it is perfectly secure [10pts]
