Quizplus · Accepted Answer

AES was approved by the NIST in late 2000 as a replacement for DES.

B) Block cipher
 A block cipher is a type of symmetric cipher that operates on fixed-length blocks of data.

C) Ciphertext
 Ciphertext is the encrypted form of plaintext, which is unreadable without decryption.

D) Data Encryption Standard (DES)
 DES is a symmetric cipher that was widely used in the past but is no longer considered secure.

E) Diffie-Hellman (DH)
 DH is a key exchange protocol that allows two parties to establish a shared secret key over an insecure channel.

F) Elliptic curve cryptography (ECC)
 ECC is a type of public key cryptography that uses elliptic curves to generate keys and perform encryption and decryption.

G) Ephemeral key
 An ephemeral key is a temporary key that is used for a single session or communication and then discarded.

H) Private key
 A private key is a secret key that is used for decryption in a public key cryptography system.

I) Public key
 A public key is a key that is used for encryption in a public key cryptography system.

J) Stream cipher
 A stream cipher is a type of symmetric cipher that operates on a stream of data, rather than fixed-length blocks.
