Q

What is Diffie-Hellman best known for?

A

Conducting key exchange and secure key distribution over an unsecure network. Used for setting up VPN tunnels using IPSec.

Q

What is Rivest, Shamir, Adelman (RSA) best known for?

A

Algorithm that relies on the mathematical difficulty of factoring large prime numbers.

Key sizes 1024-bits to 4096-bits.

Widely used in organizations. Do you have an authenticator? Then you’re using RSA.

Q

What is Elliptic Curve Cryptography (ECC) best known for?

A

It’s based on elliptic curves in algebra. It’s primarily used for mobile devices.

It uses a 256-bit key. It is 6x more efficient than an RSA algorithm.

Exam Tip: ECC is most commonly used for mobile devices and low-power computing devices because it gives equivalent protection with lower key sizes.
