Quizplus · Accepted Answer

Ciphertext is data that has been encrypted.

Answer: A
 AES is a widely used block cipher encryption algorithm.

Answer: D
 DES is a symmetric-key block cipher encryption algorithm.

Answer: E
 Diffie-Hellman is a method for securely exchanging cryptographic keys over a public channel.

Answer: F
 ECC is a type of public key cryptography that uses elliptic curves.

Answer: G
 An ephemeral key is a key that is generated for a single session or communication, and then discarded.

Answer: H
 A private key is a secret key used for decrypting data that has been encrypted with a corresponding public key.

Answer: I
 A public key is a key that is published openly to allow others to encrypt data that only the holder of the corresponding private key can decrypt.

Answer: J
 A stream cipher is a type of encryption that encrypts data one bit at a time, often used for streaming data such as audio or video.
