NSE4 · Question #370

Which of the following statements describe some of the differences between symmetric and asymmetric cryptography? (Choose two.)

The correct answer is C. Symmetric cryptography uses one pre-shared key. Asymmetric cryptography uses a pair or D. Asymmetric keys can be sent to the remote peer via digital certificates. Symmetric keys cannot. Symmetric cryptography uses a single pre-shared key for encryption and decryption, while asymmetric cryptography employs a key pair, allowing for secure key exchange via digital certificates.

Why each option

Symmetric cryptography uses a single pre-shared key for encryption and decryption, while asymmetric cryptography employs a key pair, allowing for secure key exchange via digital certificates.

AIn symmetric cryptography, the keys are publicly available. In asymmetric cryptography, the

In symmetric cryptography, the key is kept private and pre-shared, not publicly available; public keys are a characteristic of asymmetric cryptography.

BAsymmetric cryptography can encrypt data faster than symmetric cryptography

Symmetric cryptography is generally much faster at encrypting data than asymmetric cryptography because it involves less computational complexity.

CSymmetric cryptography uses one pre-shared key. Asymmetric cryptography uses a pair orCorrect

Symmetric cryptography relies on a single, shared secret key for both encryption and decryption, whereas asymmetric cryptography uses a pair of mathematically related keys (public and private) for these operations.

DAsymmetric keys can be sent to the remote peer via digital certificates. Symmetric keys cannotCorrect

Asymmetric keys can be securely distributed or exchanged using digital certificates, which bind a public key to an identity, whereas symmetric keys cannot be openly sent without risking compromise and typically require out-of-band exchange.
