Cybersecurity’s Future: Facing Post-Quantum Cryptography Peril

March 20, 2024

If bad actors get their hands on quantum computers, could the market plunge off a cliff into vulnerabilities worse than Heartbleed?

Google published a threat model recently for the coming era of post-quantum cryptography (PQC), putting into perspective potential vulnerabilities that may surface if there is not a migration from “classical cryptographic algorithms to PQC.” The risk of “store-now-decrypt-later” style attacks, where bad actors harvest data they cannot read currently with the intent of breaking the encryption in the future, intensifies with the expected advent of quantum-grade resources at their disposal.
