Study Notes

Public key cryptography involves two related keys, a public key and a private key.
Public key certificates are digital documents issued by a Certification Authority that bind a subscriber's name to a public key.
Public Key Infrastructure (PKI) is used to administer certificates and public-private key pairs.
Misconceptions about public-key encryption include that it is more secure than symmetric encryption and that it has made symmetric encryption obsolete.
Public-key cryptography addresses the difficulties of key distribution and verifying the sender of a message.
A public-key encryption scheme has six ingredients: plaintext, encryption algorithm, public and private key, ciphertext, and decryption algorithm.
Encryption with public key can provide confidentiality, integrity, and authenticity.
Encryption with private key can provide authenticity but not confidentiality or integrity.
Conventional encryption requires the same algorithm and key for encryption and decryption, while public-key encryption uses a pair of keys, one for encryption and one for decryption.
Public-key cryptography can be used for confidentiality and authentication of messages.
