True
|
|
|
False
|
|
|
Either A or B
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -As symmetric encryption employs a single key for encryption and decryption, it is quicker. Asymmetric encryption is slower than symmetric encryption because it employs two separate keys that are linked through a difficult mathematical procedure.
Detailed explanation-2: -In this type of cryptography both the parties (sender and receiver) use same key to encrypt and decrypt the message. A popular symmetric key algorithm is Data Encryption Standard (DES), there are also its modern variants such as Triple DES.
