Alice$($A$)$ and Bob$($B$)$ use ElGamal encryption system with public key parameters: $q=23,g=5,$

Alice chooses the secret key, $x_A=10.$ Bob chooses the random integer $k=6,$ and wants to

encrypt the message $m=14.$ Compute $C=(C_1,C_2).$ 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.

Note: provide a handwritten, detailed solution with all computations
