Exam 350-701 topic 1 question 455 discussion

Answer is B. Omar Santos SCOR Official Cert pg 220 The interesting thing about DH is that although the algorithm itself is asymmetric, the keys generated by the exchange are symmetric keys that can then be used with symmetric algorithms such as Triple Digital Encryption Standard (3DES) and Advanced Encryption Standard (AES).

Answer is B. RSA is not algorithm, it's cryptosystem. Meanwhile, DH is asymmetric algorithm to generate key for symmetric communication.

Diffie Hellman uses a private-public key pair to establish a shared secret, typically a symmetric key. DH is not a symmetric algorithm – it is an asymmetric algorithm used to establish a shared secret for a symmetric key algorithm. https://doubleoctopus.com/security-wiki/encryption-and-cryptography/diffie-hellman-algorithm/

D. Diffie-Hellman (DH) is a key agreement protocol that enables two parties to establish a shared secret key over an insecure communication channel. It is considered a key-establishment or key-agreement algorithm. RSA, on the other hand, is a public-key encryption algorithm that is often used to encrypt and digitally sign data. It is considered an asymmetric algorithm, as it uses two different keys, one for encryption and one for decryption. It is not intended to output symmetric keys, but it is often used to encrypt symmetric keys and then exchange them securely

RSA is Asymetric Alg.
