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. WebDec 17, 2024 · It says that CTR and OFB modes are safe against quantum adversaries. You have to understand the attack model that assumes. It assumes a scenario where the attacker can make quantum entangled queries to the Oracle, and get entangled responses back; what they show that, even in that scenario, the attacker does not have any … WebApr 12, 2015 · 1 Answer Sorted by: 1 No OFB_DRBG isn't directly vulnerable to attacks.
