This is mathematically proven.Fri, 03 Jan 2025 00:00:00 GMThttps://fudorfact.com/blog/what-is-post-quantum-cryptography/https://fudorfact.com/blog/what-is-post-quantum-cryptography/A beginner's guide to understanding post-quantum cryptography, why it matters, and what's being done about it.Fri, 03 Jan 2025 00:00:00 GMThttps://fudorfact.com/hot-takes/sample-hot-take/https://fudorfact.com/hot-takes/sample-hot-take/Our reaction to @cryptopundit's takeFri, 03 Jan 2025 00:00:00 GMThttps://fudorfact.com/verdicts/quantum-break-encryption-2030/https://fudorfact.com/verdicts/quantum-break-encryption-2030/While quantum computing poses real threats to some cryptographic systems, claims of imminent total cryptographic collapse are overblown. Post-quantum cryptography standards are already being deployed.Thu, 02 Jan 2025 00:00:00 GMThttps://fudorfact.com/verdicts/harvest-now-decrypt-later/https://fudorfact.com/verdicts/harvest-now-decrypt-later/Nation-state actors are collecting encrypted data today to decrypt once quantum computers are available. Organizations with long-term secrets should migrate to post-quantum cryptography now.Wed, 01 Jan 2025 00:00:00 GMThttps://fudorfact.com/verdicts/bitcoin-quantum-collapse/https://fudorfact.com/verdicts/bitcoin-quantum-collapse/While Bitcoin's ECDSA signatures are theoretically vulnerable, the threat timeline is uncertain and migration paths exist. Panic is unwarranted, but preparation is prudent.Mon, 30 Dec 2024 00:00:00 GMThttps://fudorfact.com/verdicts/aes-256-quantum-safe/https://fudorfact.com/verdicts/aes-256-quantum-safe/Grover's algorithm reduces AES-256 security to ~128 bits against quantum attacks. This is still considered secure, but 'quantum-safe' is an oversimplification.Sat, 28 Dec 2024 00:00:00 GMThttps://fudorfact.com/verdicts/replace-cryptography-immediately/https://fudorfact.com/verdicts/replace-cryptography-immediately/A measured, risk-based transition to post-quantum cryptography is appropriate. Panic-driven wholesale replacement creates more risk than it prevents.Wed, 25 Dec 2024 00:00:00 GMT
