WebThe four different modes of operation (CBC, CFB, OFB, and CTR) all protect data confidentiality, and are widely used in numerous security designs and cryptographic … WebCTR mode is like OFB; the difference again is the feedback. CTR mode uses a counter, so this mode shares the same advantages as OFB in that patterns are destroyed and errors do not propagate. However, there is an additional advantage: since the feedback can be as simple as an ascending number, CTR mode encryption can be executed in parallel.
