Quizplus · Accepted Answer

DES is a symmetric block cipher that uses a 56-bit key and encrypts data in 64-bit blocks.

Answer: F
 ECC is a public-key cryptography system that uses elliptic curves instead of prime numbers, offering a higher level of security.

Answer: G
 Ephemeral keys are temporary keys used to encrypt data for a short period, usually in Diffie-Hellman key exchange.

Answer: H
 A private key is a secret key used in symmetric cryptography systems to encrypt and decrypt data.

Answer: I
 A public key is a key used in public-key cryptography systems to encrypt data and send it to the receiver, who possesses the corresponding private key.

Note: AES and stream cipher are not included as options as they do not fit the given description.
