Computer Science for IGCSE & O level - Data Transmission (Section 1 - No. 37)
Which of the following is a main difference between Symmetric and Asymmetric Encryption?
Symmetric encryption uses public and private keys while Asymmetric uses only the symmetric key.
Symmetric uses same key for encryption and decryption while Asymmetric uses two different keys.
Symmetric is easier and cheaper to implement while Asymmetric is better and more secure.
Symmetric uses a public key for data transmission while Asymmetric uses both public and private keys.
Explication
Symmetric encryption uses the same key for both encryption and decryption, while Asymmetric uses two different keys.
