Cryptography Quiz

Symmetric key cryptography is more secure than asymmetric key cryptography.

Symmetric key cryptography is faster than asymmetric key cryptography.

Symmetric key cryptography uses the same key for both encryption and decryption, while asymmetric key cryptography uses different keys for encryption and decryption. (correct)

Symmetric key cryptography can only be used for digital communication, while asymmetric key cryptography can be used for both digital and analog communication.

Public key cryptography encrypts the plaintext by shifting the letters a certain number of positions in the alphabet.

Public key cryptography rearranges the letters in the plaintext to form a secret message.

Public key cryptography uses different keys for encryption and decryption. (correct)

Public key cryptography uses the same key for both encryption and decryption.

Physical security protects against unauthorized access to the encrypted data. (correct)

Physical security is only important for symmetric key cryptography.

Physical security has no impact on the cryptographic security of data.

Physical security ensures that the cryptographic keys are stored securely.
