CompTIA Security+ SY0-701 Practice Question

The Diffie-Hellman algorithm is specifically designed for secure key exchange over insecure channels without requiring prior shared secrets. It enables two parties to independently generate a shared secret key, which can then be used for symmetric encryption. Symmetric key distribution assumes that keys are already shared or delivered securely, which doesn't address the need to establish keys without prior arrangement. RSA digital signatures provide authentication and integrity but are not primarily used for key establishment. MD5 is a hashing algorithm used for data integrity verification, not for key exchange or encryption key establishment.
