El Gamal Encryption Problem: Alice wants to let Bob know the number of widgets being shipped out by their company. This number is confidential so she must encrypt it before she sends it to Bob. They decide to use the Diffie-Hellman Key Exchange Protocol. They use the public base a=2 and modulus N=59. Bob chooses the number s=3 and computes his cryptography key Kg. Bob sends his cryptography key Ka to Alice

Question 7 El Gamal Encryption Problem: Alice wants to let Bob know the number of widgets being shipped out by their company, This number is confidential so she must encrypt it before she sends it to Bob. They decide to use the Diffie-Hellman Key Exchange Protocol. They use the public base a=2 and modulus N=59. Bob chooses the number s-3 and computes his cryptography key Kg Bob sends his cryptography key Kg to Alice. Alice chooses the number r=4 and computes her cryptography key KA Alice sends her cryptography key KA to Bob. Alice encrypts her integer message and then sends Bob the encrypted message which contains the following "28". How many widgets will be shipped? Your answers should be an integer without the mod since mod is implied. Show all of your work in your written submission.
