Which of the following correctly explains the difference between 'symmetric' and 'asymmetric' encryption?

Q: Answer-Which of the following correctly explains the difference between 'symmetric' and 'asymmetric' encryp...

Symmetric AES, DES, 3DES is fast, efficient and ideal for bulk data encryption. The challenge is secure key distribution. Asymmetric RSA, ECC, Diffie-Hellman is where public key encryptsverifies private key decryptssigns. It solves key distribution but is computationally slow. In practice, both are combined asymmetric encryption securely exchanges a symmetric session key, then symmetric encryption handles bulk data TLSSSL uses this hybrid approach for internet banking.

A Symmetric encryption uses the same key for both encryption and decryption; asymmetric encryption uses a mathematically linked key pair (public and private key)

B Symmetric encryption uses one key for encryption and a different key for decryption; asymmetric uses the same key for both

C Symmetric encryption is slower and stronger; asymmetric encryption is faster and weaker

D Symmetric encryption is used only for data at rest; asymmetric is used only for data in transit

E Symmetric encryption uses hardware; asymmetric encryption uses software only
