For stream-oriented transmission over noisy channel you would typically use _______ mode.
A) ECB
B) CTR
C) OFB
D) CBC

Question

Quizplus · Accepted Answer

Stream-oriented transmission involves sending data continuously over a channel, which means that the encryption mode should be able to handle individual bits and also have error-propagation resistance. Among the given options, OFB (Output Feedback) mode is the best choice as it involves encrypting a randomly generated key stream that is XORed with the plaintext to produce the ciphertext. This mode ensures error propagation is limited to a single bit and it does not require synchronization between the sender and receiver. Therefore, OFB is the best option for stream-oriented transmission over a noisy channel.
