Question

Consider the following statements about symmetric encryption :
A. Same key for encryption and decryption

B. Faster than asymmetric encryption

C. Key distribution is simpler

D. Stream ciphers encrypt one bit byte at a time

E. Block ciphers operate on groups of bits

Choose the correct answer from the options given below :

• A. A, B, C, E only
• B. B, C, D only
• C. A, C, D, E only
• D. A, B, D, E only

Hint:

Symmetric = Shared Key. Asymmetric = Public/Private pair. If you see "Simple Key Distribution," it's referring to Asymmetric/Public-key cryptography!

Answer 1

The Correct Option is D
