O’Brien emphasizes the need for quantum-resistant encryption methods to counter both quantum and conventional modes of attack. He points out that some candidates for quantum-resistant cryptographic algorithms have already been compromised by existing hardware, making immediate action crucial.
Highlighting the flexibility of a hybrid approach like X25519Kyber768, O’Brien underscores its capacity to deploy and test new quantum-resistant algorithms while preserving the security of connections through existing reliable algorithms.
Although O’Brien estimates it may take several years for quantum computers capable of cracking encryption to materialize—ranging from 5 to 50 years—he underscores the significance of safeguarding internet traffic now. The urgency arises from the possibility of data being intercepted now and decrypted when quantum technology becomes practical.
