Cryptography Chart

Encryption turns plaintext into ciphertext

Steganography hides information within other information

Perfect Forward Secrecy Random Asymmetric keys used for each transaction

Symmetric Uses single key, can encrypt large amouts of data quickly (large amounts of data)

Asymmetric Uses 2 keys, private & public (small amounts of data)

S/MIME Secure/Multipurpose Internet Mail Exchange - Asymmetric

Diffie-Hellman Asymmetric.secure tunnel for symetic data Used by Internet Key Exchange (IKE) UDP port 500

XOR Exclusive OR , output is comparison of 2 bits

Stream cipher Applies encryption to one bit at a time

Block cipher Encrypts entire block of data such as 128 bits at a time

PRNG Pseudo-Random Number Generator

Nonce Often a random number that is used only once

3 types of data encryption. At Rest / In Flight / In Use

Encryption supports Confidentiality

Integrity

Non-Repudiation

Resiliency

Authentication
