Not started
Public key cryptography (asymmetric cryptography), invented by Diffie and Hellman in 1976, uses two mathematically related digital keys — a public key and a private key — to solve the key-exchange problem of symmetric encryption.
- Define public key cryptography and identify its inventors.
- Explain how public and private keys are used together.
- Describe one-way (irreversible) mathematical functions.
- Identify what problem public key cryptography solves.
