Which mechanism would most securely facilitate the exchange of encryption keys over a public network?
Hash-Based Message Authentication Code (HMAC)
Remote Access Service (RAS)
Office of Personnel Management (OPM)
Elliptic Curve Diffie-Hellman (ECDH)
The correct answer is Elliptic Curve Diffie-Hellman (ECDH) because it is a protocol specifically designed to allow two parties to establish a shared secret over an unsecured communication channel. Unlike RSA, which is an asymmetric encryption algorithm not primarily used for key exchange, and HMAC, which stands for Hash-Based Message Authentication Code and is used for ensuring the integrity of the message, ECDH provides a secure method for key exchange that leverages the properties of elliptic curves to enhance security and efficiency.
