Quantum Cryptography Consulting: Build $1.5M/Year Post-Quantum Practice (2025)

The post-quantum cryptography market will reach $2.9 billion by 2025 (MarketsandMarkets), as NIST's CRYSTALS-KYBER becomes standard for government systems. This 8,000+ word guide reveals how to build a premium quantum security practice at $600-$1,200/hour rates. You'll discover:
- 5 elite service packages ($150k-$750k engagements)
- Quantum migration frameworks
- Lattice-based encryption implementations
- How to close DoD contracts with 4 proven templates
Why Quantum Security Became Mandatory in 2025
New threats and regulations driving demand:
Driver | Impact | Deadline |
---|---|---|
NIST PQC Standardization | Mandatory for federal systems | Q1 2025 |
FIPS 203/204/205 | New encryption standards | 2025 Compliance |
Quantum Harvest Attacks | Data being collected now | Decryption by 2030 |

Market Data: 85% of enterprises lack quantum-resistant encryption (Ponemon Institute).
3 Post-Quantum Migration Frameworks
1. NIST Migration Framework
Government Standard
- CRYSTALS-KYBER (Key Exchange)
- CRYSTALS-Dilithium (Signatures)
- 5-phase migration path
2. CNSA 2.0
Military Standard
- NSA-approved algorithms
- High-assurance systems
- Classified data protection
3. Hybrid PKI Framework
Enterprise Transition
- RSA + lattice-based dual keys
- Gradual migration
- Backward compatibility
180-Day Migration Roadmap
Phase 1: Crypto Inventory (Days 1-30)
openssl list -public-key-algorithms | grep -E "RSA|ECDSA|DSA"
# Python PQ Crypto Detection
from cryptography.hazmat.primitives.asymmetric import rsa, ec
import sys
def check_quantum_safe(algo):
quantum_unsafe = [rsa.RSAPrivateKey, ec.EllipticCurvePrivateKey]
return not any(isinstance(algo, x) for x in quantum_unsafe)
Deliverables:
- Vulnerable algorithm inventory
- Data sensitivity mapping
- Risk scoring report
Phase 2: Prototype Deployment (Days 31-120)

Key Activities:
Phase 3: Full Migration (Days 121-180)
Algorithm | Type | Key Size | Use Case |
---|---|---|---|
CRYSTALS-KYBER | Lattice-based KEM | 2.5KB | TLS 1.3 |
FALCON | Lattice-based Signature | 1.3KB | Code Signing |
SPHINCS+ | Hash-based Signature | 8KB | Long-term Data |
