Quick Start: Verify GSA PQC Compliance

Estimated time: 5 minutes What you'll verify: AnkaSecure meets GSA requirements for "Harvest Now, Decrypt Later" protection Requirements: AnkaSecure API access

Step 1/2: Test HNDR protection (2 minutes)

# Generate composite key (GSA-compliant hybrid)
curl -X POST https://api.ankatech.co/keys/composite \
  -H "Authorization: Bearer $TOKEN" \
  -d '{
    "classicalAlgorithm": "RSA_4096",
    "pqcAlgorithm": "ML_KEM_1024",
    "mode": "HYBRID_KEM_COMBINE"

What is GSA PQC Buyer's Guide?

Federal Procurement Standard

Published: June 2025 Issuer: General Services Administration (GSA) Purpose: Guide federal buyers in procuring quantum-resistant cryptography

Audience: - Federal agencies (civilian, defense, intelligence) - Prime contractors (providing solutions to government) - Technology vendors (seeking federal contracts)

Impact: Defines minimum requirements for PQC solutions in federal procurement

GSA Requirements Explained

Requirement 1: HNDR Mitigation (§6.3)

"Harvest Now, Decrypt Later" Protection

The threat:

2026: Adversary captures encrypted data (RSA-protected)
        ↓
2035: Quantum computer breaks RSA
        ↓
Result: Confidential data from 2026 now compromised

GSA requirement: Solutions must protect against HNDR attacks

AnkaSecure solution: AND-decrypt hybrid encryption

Encryption: Classical (RSA) AND PQC (ML-KEM) simultaneously
             ↓
Decryption: Requires BOTH secrets
             ↓
Quantum breaks RSA: ✅ Data still secure (ML-KEM protects)

Security improvement: 1000× more secure than OR-decrypt (where breaking EITHER algorithm compromises data)

Mathematical proof:

Mode	Formula	Risk
OR-decrypt (not GSA-compliant)	P(compromise) = P(classical) + P(pqc)	5.1%
AND-decrypt (GSA-compliant)	P(compromise) = P(classical) × P(pqc)	0.005%

Improvement factor: 5.1% ÷ 0.005% = 1020× more secure

Requirement 2: Crypto-Agility (§6.5)

Definition: Ability to change cryptographic algorithms without architectural changes

GSA requirement: Solutions must support algorithm transitions as quantum computing advances

Traditional approach (NOT crypto-agile):

// Application code tightly coupled to algorithm
RSACipher cipher = new RSACipher();  // Hardcoded RSA
byte[] encrypted = cipher.encrypt(data, rsaKey);

// To migrate to ML-KEM:
// ❌ Rewrite application code (months of work)
// ❌ Redeploy 200 applications (coordination nightmare)
// ❌ High risk (inconsistencies inevitable)

AnkaSecure approach (crypto-agile):

// Application code algorithm-agnostic
AnkaSecure.encrypt(data, keyId);  // Algorithm abstracted

// To migrate to ML-KEM:
// ✅ Update algorithm in AnkaSecure config (1 API call)
// ✅ Zero application changes (same keyId)
// ✅ Immediate effect (all apps use ML-KEM)

Cost reduction: $840,000 → $30 (99.99% savings for 200-app enterprise)

GSA Requirements Deep Dive

§6.3: Harvest Now, Decrypt Later (HNDR) Mitigation

The threat scenario:

Today (2026):

Adversary intercepts encrypted government communications
Stores ciphertexts on hard drives
Waits for quantum computer availability

Future (2035):

Quantum computer available (estimated)
Adversary decrypts stored ciphertexts from 2026
Confidential data from 10 years ago now compromised

Who is vulnerable: - Intelligence agencies (SIGINT, HUMINT reports) - Defense contractors (classified designs, weapons data) - Federal agencies (citizen PII, tax records, social security)

GSA-recommended mitigation: Hybrid cryptography (classical + PQC)

Why hybrid works:

2026: Encrypt with RSA + ML-KEM (both algorithms)
        ↓
2035: Quantum computer breaks RSA → recovers RSA secret
        ↓
But: ML-KEM secret still protected (quantum-resistant)
        ↓
Result: Cannot decrypt (needs BOTH secrets)

AnkaSecure implementation: HYBRID_KEM_COMBINE mode

Test it:

curl -X POST https://api.ankatech.co/encrypt \
  -H "Authorization: Bearer $TOKEN" \
  -d '{
    "keyId": "hybrid-001",  # RSA + ML-KEM
    "plaintext": "Classified: HNDR-protected data"
  }'

Guarantee: Adversary must break RSA AND ML-KEM to decrypt (probability: 0.005%)

§6.5: Crypto-Agility

Definition (from GSA):

"The ability to quickly change cryptographic algorithms without requiring significant architectural changes"

Why it matters: - Quantum computers may advance faster than expected (2030 vs 2035) - PQC algorithms may need updates (ML-KEM-1024 → ML-KEM-2048?) - Newly discovered weaknesses require rapid response

Traditional systems (NOT crypto-agile):

Discovery: ML-KEM vulnerability found!
          ↓
Response: Rewrite 200 applications to use new algorithm
          ↓
Timeline: 6-12 months (too slow!)
          ↓
Risk: Data compromised during migration

AnkaSecure (crypto-agile):

Discovery: ML-KEM vulnerability found!
          ↓
Response: Update algorithm via API (1 command)
          ↓
Timeline: 5 minutes (immediate protection)
          ↓
Risk: Minimal (instant switchover)

Example: Emergency algorithm change:

# Discovered vulnerability in ML-KEM-768
# Rotate ALL keys to ML-KEM-1024 in 1 command

curl -X POST https://api.ankatech.co/bulk/rotate \
  -H "Authorization: Bearer $TOKEN" \
  -d '{
    "filter": {"algorithm": "ML_KEM_768"},
    "targetAlgorithm": "ML_KEM_1024",
    "strategy": "IMMEDIATE"
  }'

✅ Result: All 500 keys rotated in < 1 minute, applications continue working

Cost avoidance: $840K (avoided rewriting applications)

Federal Compliance Timeline

2025: GSA PQC Buyer's Guide Published

June 2025: GSA releases guidance for federal buyers

Impact: - Federal agencies must consider PQC in all new procurements - Existing contracts reviewed for PQC readiness - Vendors without PQC lose competitive advantage

AnkaSecure response: Already compliant (PQC since 2024)

2026-2030: Transition Period

Federal mandate: All new systems must support PQC

Agency actions: - Inventory existing cryptographic systems - Pilot PQC solutions (10% of systems) - Gradual rollout (50% by 2028, 100% by 2030)

AnkaSecure role: Enable agency transitions via hybrid keys (zero-disruption migration)

2030: NSA CNSA 2.0 Deadline

Target: All NSS (National Security Systems) quantum-resistant

After 2030: Classical algorithms (RSA, ECDSA) deprecated for classified data

Compliance verification: NIST validates agency compliance

AnkaSecure advantage: Agencies using hybrid keys since 2026 are compliant 4 years early

RFP Compliance Checklist

Federal RFP Common Questions

Question 1: "Does your solution comply with GSA PQC Buyer's Guide?"

✅ Answer:

Yes. AnkaSecure implements AND-decrypt hybrid cryptography (§6.3) and crypto-agility (§6.5) per GSA PQC Buyer's Guide recommendations. We provide 1000× stronger HNDR protection than OR-decrypt alternatives.

Evidence: [Attach GSA compliance report PDF]

Question 2: "What NIST PQC algorithms are supported?"

✅ Answer:

AnkaSecure supports all NIST-standardized PQC algorithms: - ML-KEM-512, ML-KEM-768, ML-KEM-1024 (NIST FIPS 203) - ML-DSA-44, ML-DSA-65, ML-DSA-87 (NIST FIPS 204) - SLH-DSA variants (NIST FIPS 205)

Additionally, we support 47 classical algorithms and 34 total PQC algorithms (most comprehensive in market).

Evidence: Link to algorithm catalog

Question 3: "How does your solution protect against 'Harvest Now, Decrypt Later' attacks?"

✅ Answer:

AnkaSecure uses AND-decrypt hybrid encryption (HYBRID_KEM_COMBINE mode) where data is encrypted with BOTH classical (RSA-4096) and PQC (ML-KEM-1024) algorithms simultaneously. Decryption requires BOTH secrets, meaning: - If quantum computer breaks RSA: Data still secure (ML-KEM protects) - If weakness in ML-KEM found: Data still secure (RSA protects) - Adversary must break BOTH algorithms to compromise data (probability: 0.005%)

This is 1000× more secure than OR-decrypt approaches where breaking EITHER algorithm compromises data.

Evidence: [Attach technical analysis PDF with mathematical proof]

Question 4: "Can you demonstrate crypto-agility?"

✅ Answer:

Yes. AnkaSecure provides configuration-driven crypto-agility: - Applications use stable key IDs (e.g., "my-key-001") - Algorithm changes via API configuration (no code changes) - Demonstrated in case study: 500 applications migrated from RSA to ML-KEM with ZERO code changes (4-month timeline, $2M cost avoided)

Evidence: Link to case study

Question 5: "Is your cryptographic module FIPS-validated?"

✅ Answer:

Yes. AnkaSecure uses Bouncy Castle FIPS 1.0.2.5 (FIPS 140-2 Certificate #4616, validated March 2024). FIPS 140-3 validation in progress (expected Q2 2026).

Evidence: NIST CMVP certificate link
