  • Where would I find this info? This unit explains public key.
• Understand how the RSA process works, with a simple example.
• Understand how elliptic curve cryptography works, with a simple example.
• Explain the operation of PGP.
• Understands how the private key is used to check the identity of the sender, and how public key is used to preserve the privacy of the message.
