What is a primitive root in cryptography?
Excuse me, could you please clarify what a primitive root is in the context of cryptography? I'm curious to understand how it plays a role in ensuring the security and integrity of cryptographic systems. I've heard it mentioned in discussions about number theory and modular arithmetic, but I'm not entirely sure how it ties in with cryptography specifically. Could you elaborate on its significance and any practical applications it might have in the field?
