Financial institutions are the highest-value targets for "harvest now, decrypt later" attacks. Transaction records, account credentials, and inter-bank communications encrypted today with RSA or ECC will be vulnerable once cryptographically relevant quantum computers arrive.
Financial data has uniquely long sensitivity horizons. A mortgage originated today remains sensitive for 30 years. Trade secrets, M&A communications, and customer financial records retain their value for decades. Adversaries harvesting this encrypted data today are making a rational investment: store it now, decrypt it when quantum computers mature.
High-frequency trading and real-time payment networks demand sub-millisecond cryptographic operations. Software-only PQC implementations introduce latency penalties incompatible with these performance requirements. A signing workflow processing 100,000 signatures per day would require 4 to 5 additional servers with software PQC, or a single QUAC-100 card.
Regulatory pressure is accelerating. Financial regulators globally are issuing guidance on quantum risk assessment and cryptographic migration planning. Early movers gain competitive advantage.
| Attack Vector | Description |
|---|---|
| Inter-Bank Communication | SWIFT messages, FedWire transfers, and correspondent banking communications encrypted with classical algorithms vulnerable to future quantum decryption. |
| Transaction Signing | Digital signatures on financial transactions provide non-repudiation. Quantum attacks on ECDSA/RSA could enable transaction forgery at scale. |
| Key Management | Root CA keys, HSM master keys, and key exchange protocols are crown jewels. Compromising these enables retroactive decryption of all protected data. |
| Payment Card Networks | EMV chip authentication and payment tokenization rely on ECC. Billions of payment terminals and cards will need quantum-resistant upgrades. |
Payment processors and exchanges executing millions of transactions daily need cryptographic signing that keeps pace with business volume. The QUAC-100 delivers 67,000 ML-DSA-65 signatures per second with <15 us latency, replacing 4 to 5 additional servers with a single PCIe card. PKCS#11 integration means existing HSM workflows remain unchanged.
Targets: Payment Processing, Trade Execution, Settlement Systems
| Signing Performance | Throughput |
|---|---|
| ML-DSA-44 Sign | 100K ops/s |
| ML-DSA-65 Sign | 67K ops/s |
| ML-DSA-87 Sign | 45K ops/s |
| Latency (DSA-65) | <15 us |
Legacy Thales Luna and nCipher HSMs were designed for RSA-2048/4096 and have memory architectures insufficient for PQC key sizes (ML-DSA public keys are 1.9KB vs. RSA-2048's 256 bytes). Their serial processing model tops out at 1,000 to 10,000 operations per second. The QUAC-100 delivers 1.2M+ ML-KEM-512 operations per second with native hybrid mode support and integrated QRNG.
Targets: Key Management, PKI, Code Signing, Certificate Authority
| vs. Legacy HSM | Result |
|---|---|
| PQC Native | Yes (hardware) |
| Throughput | 20 to 200x faster |
| Hybrid Mode | Single API call |
| QRNG | Integrated (>800 Mbps) |
