The Quantum Threat
Quantum computers will render classical cryptography obsolete. Post-quantum migration is urgent.
What is the Quantum Threat?
Quantum computers use qubits and algorithms like Shor's to solve problems that take thousands of years on classical computers. This allows breaking RSA, ECC, and DH in hours — compromising all current digital security infrastructure.
⚠️ The "Harvest Now, Decrypt Later" attack is already underway: encrypted data today is being captured for decryption when quantum computers become available.
Threat Timeline
The projected evolution of quantum computing and its impact on cryptography.
Preparation
Mass capture of encrypted data. NIST finalizes PQC standards. Migration must start now.
Critical Risk
First quantum computers capable of attacking RSA-2048 and ECDSA. Migration deadline.
Classical Crypto Obsolete
All classical asymmetric cryptography vulnerable. Only PQC offers protection.
Vulnerable Algorithms
Impact of quantum computers on current cryptographic algorithms.
| Algorithm | Type | Status | Quantum Time |
|---|---|---|---|
| RSA-2048 | Encryption | Broken | ~8h |
| ECDSA P-256 | Signature | Broken | ~2h |
| DH-2048 | Key Exchange | Broken | ~8h |
| AES-128 | Encryption | Weakened | Grover |
| SHA-256 | Hash | Weakened | Grover |
| AES-256 | Encryption | Safe | — |
Harvest Now, Decrypt Later
Adversaries are capturing encrypted data today to decrypt it in the future with quantum computers.
Financial Transactions
Banking and payment data with decades of value.
Health Records
Personal medical data with lifelong confidentiality requirements.
Government Secrets
Classified information and national security data.
Communications
Emails, messages, and calls that can be intercepted and stored.
The Solution: Post-Quantum Cryptography
NIST-standardized algorithms resistant to quantum attacks.
ML-KEM (Kyber)
FIPS 203Secure Key Encapsulation for quantum-safe key exchange.
ML-DSA (Dilithium)
FIPS 204Lattice-based digital signatures, efficient and secure.
SLH-DSA (SPHINCS+)
FIPS 205Stateless hash-based signatures — conservative security.
Protect Yourself Now
Don't wait for the threat. Migrate to post-quantum cryptography today.
