To sign the message \( M = 20 \) using the Digital Signature Algorithm (DSA), Alice will follow these steps: ### 1. Parameter Setup Alice already has the following parameters: - \( p = 83 \) (a large prime number) - \( q = 41 \) (a divisor of \( p - 1 \), used to form the group order) - \( g = 2 \) (the generator element) - \( a = 3 \) (her private key, which is secret) - \( M = 20 \) (the message to be signed) - \( k = 8 \) (a secret random value, used only once) ### 2.
