Asymmetric Algorithms

Question 1

What is Diffie Hellman (DH)?

Answer 1

Asymmetric

Used for the key exchange inside of creating a VPN tunnel establishment as part of IPSec

Question 2

What is RSA (Rivest, Shamir, and Adelman)?

Answer 2

Asymmetric Algorithm

Relies on the mathematical difficulty of factoring large prime numbers

Used for key exchange, encryption, and digital signatures

Question 3

What is the Elliptic Curve Cryptography (ECC)?

Answer 3

Heavily used in mobile and low computing devices and its based on the algebraic structure of elliptical curves over finite fields to define its keys

Lower key size

ECDH (Elliptic Curve Diffie-Hellman)
ECDHE (Elliptic Curve Diffie-Hellman Ephemeral)
ECDSA (Elliptic Curve Digital Signature Algorithm)
