  39. PKI Explained • Crypto Terms • Encryption • Takes input data and a secret key and outputs data that appears to bear no relation to the input data. • Hashing • Takes input data and outputs a fixed size chunk of data that uniquely represents the input data. • Symmetric Key • Same key to encrypt/decrypt data – known receiver • Asymmetric Key • Different key to encrypt/decrypt data – unknown receiver

  40. PKI Explained • Crypto Examples • Symmetric Key • Deployment: IPSec (AH, ESP), Database, Tape, DRM • Asymmetric Key • Deployment: HTTPS (HTTP & SSL/TLS), WLAN, IPSec (IKE), S-MIME, SSH, SFTP • Hash Functions • HMAC: MD5, SHA1/2 • Encryption • Symmetric Algorithms: AES, Twofish, Serpent, DES, Triple DES (TDES) • Asymmetric Algorithms: Diffie-Hellman, RSA, ECC, DSA, El Gamal

  41. PKI Explained • PKI: 50,000 Feet • Asymmetric Key & HMAC • Public & Private Key • Leverages Symmetric Algorithm for Plaintext • Architecture • Sender: Private—Public  Receiver: Public—Private • Analogy • Sender: Cipher—USPS  Receiver: USPS—Cipher
