FUSTER, LOW LOM
Which of the following correctly describes the Output Feedback Mode (OFB) in cryptography?
A. OFB mode encrypts plaintext through a feedback mechanism that combines previous ciphertext blocks
with the plaintext
B. OFB mode generates keystream blocks, which are then XORed with the plaintext blocks to produce the
ciphertext
C. OFB mode processes plaintext blocks independently, without using any feedback from previous blocks
D. OFB mode combines plaintext blocks with a counter and an initial value to produce the ciphertext
