What are public key encryption schemes based on the Diffie-Hellman key exchange?
Could you elaborate on the concept of public key encryption schemes rooted in the Diffie-Hellman key exchange? The Diffie-Hellman protocol essentially establishes a secure means for two parties, let's call them Alice and Bob, to jointly agree upon a shared secret key, even in the absence of a pre-existing shared secret. This is achieved through the exchange of publicly shared parameters and individually chosen secret values. Could you elaborate on how this key exchange forms the foundation for public key encryption schemes? Specifically, how does the Diffie-Hellman key exchange enable the secure transmission of encrypted messages using public and private key pairs?
