Question: Alice ( A ) and Bob ( B ) use ElGamal encryption system with public key parameters: q = 2 9 , g = 2

Alice(A) and Bob(B) use ElGamal encryption system with public key parameters: q=29,g=2,
Alice chooses the secret key, xA=5. Bob chooses the random integer k=8, and wants to encrypt
the message m=15. Compute C=(C1,C2). Note: 1. To be fully graded, provide a detailed
solution with all computations included. 2. Feel free to make assumptions for any necessary values
not explicitly provided in the question.
