On the quantum security of ocb
Web17 de mai. de 2024 · OCB is a bit less fragile than GCM against repeated nonces. For example, if a nonce is used twice, an attacker that sees the two ciphertexts will notice that, say, the third plaintext block of the first message is identical to the third plaintext block of the second message. With GCM, attackers can find not only duplicates but also XOR ...
