What is post-quantum encrypted video?

Post-quantum encrypted video uses cryptographic algorithms that are resistant to attacks from both classical computers and future quantum computers. V100 uses ML-KEM-768 (FIPS 203) for key exchange and ML-DSA-65 (FIPS 204) for digital signatures, combined with X25519 in a hybrid scheme that provides security even if one algorithm is broken.

Does post-quantum encryption add latency to video calls?

No. V100's post-quantum encryption adds zero measurable latency to video calls. The ML-KEM-768 key encapsulation completes in under 1 millisecond during session setup, and the symmetric AES-256-GCM encryption used for the actual media stream is identical in performance to classical implementations. The hybrid key exchange adds approximately 1,568 bytes to the initial handshake -- imperceptible on any modern connection.

Why does V100 use a hybrid key exchange instead of pure post-quantum?

V100 uses ML-KEM-768 combined with X25519 in a hybrid scheme to provide defense in depth. If ML-KEM-768 were found to have a vulnerability, X25519 still provides classical security. If a quantum computer breaks X25519, ML-KEM-768 still provides quantum resistance. This approach follows NIST and NSA guidance for transitioning to post-quantum cryptography.

What does V100's post-quantum encryption protect?

V100's post-quantum encryption protects all video and audio media streams during live calls, all stored recordings and transcripts at rest (AES-256-GCM), API credentials and session tokens, meeting metadata and participant information, AI-generated summaries and meeting notes, and webhook payloads. Every recording and transcript also receives an ML-DSA-65 Dilithium digital signature for tamper-proof integrity verification.

Do competitors offer post-quantum encryption for video?

As of March 2026, no other video API provider offers post-quantum encryption. Twilio, Vonage, Daily, Agora, Zoom SDK, and Amazon Chime SDK all rely exclusively on classical encryption (ECDH/RSA key exchange, ECDSA/RSA signatures). V100 is the first and only video platform to implement FIPS 203/204 post-quantum cryptography across its entire stack.

Why Post-Quantum Encryption Matters for Video

Quantum computers capable of breaking RSA-2048 and ECDH are projected to exist within the next 10 to 15 years. But the threat is not in the future -- it is happening now. Adversaries are already executing "harvest now, decrypt later" attacks: recording encrypted traffic today with the intention of decrypting it once quantum computers become available. For video platforms handling sensitive conversations -- healthcare consultations, legal depositions, financial negotiations, defense briefings -- this means every session recorded today could be exposed in the future.

Harvest Now, Decrypt Later

Nation-state adversaries are recording encrypted data streams now, storing them until quantum computers can break classical encryption. Video recordings of sensitive meetings are high-value targets. Once decrypted, the damage is irreversible -- you cannot un-share a medical consultation or un-reveal a legal strategy.

Regulatory Mandate

NIST finalized ML-KEM (FIPS 203) and ML-DSA (FIPS 204) as federal post-quantum standards in August 2024. NSA CNSA 2.0 requires all National Security Systems to transition to post-quantum cryptography by 2033. OMB M-23-02 mandates a post-quantum migration inventory for all federal agencies. The compliance clock is running.

Data Retention Exposure

Healthcare records must be retained for 6 to 30 years depending on jurisdiction. Legal evidence may be stored indefinitely. Financial records carry 7-year minimums. If your video recordings are encrypted with classical-only cryptography today, they will be vulnerable for the majority of their retention period.

What V100's Post-Quantum Encryption Protects

Post-quantum encryption is not applied selectively -- it protects every layer of the V100 stack. From the moment a session is created to the moment a recording is retrieved years later, every byte is protected against quantum attacks.

Live Media Streams

Every video and audio stream in a live call is encrypted end-to-end using session keys negotiated via ML-KEM-768 + X25519 hybrid key exchange. Even if the V100 media server were compromised, it cannot decrypt the media content.

Video streams (VP8/VP9/H.264/AV1)

Audio streams (Opus)

Screen sharing data

Recordings and Transcripts

All stored assets are encrypted at rest with AES-256-GCM and signed with ML-DSA-65 Dilithium signatures. The encryption keys themselves are wrapped with post-quantum key encapsulation, so even the key material is quantum-resistant.

Video recordings (MP4/WebM)

Transcripts (JSON/SRT/VTT)

AI-generated summaries and meeting notes

Credentials and Tokens

API keys are wrapped in a Kyber + AES-256-GCM envelope at the gateway level. Session tokens, webhook secrets, and internal service credentials all use post-quantum key encapsulation. Credential theft via quantum attack is mathematically infeasible.

Cryptographic Architecture

V100's post-quantum encryption stack implements a defense-in-depth approach with three independent cryptographic layers. Each layer uses NIST-standardized algorithms with no proprietary modifications.

Key Exchange: ML-KEM-768 + X25519 Hybrid

Session keys are negotiated using a hybrid scheme that combines ML-KEM-768 (lattice-based, FIPS 203) with X25519 (elliptic curve Diffie-Hellman). The shared secret is derived by concatenating both key exchange outputs and running them through HKDF-SHA256. This means an attacker must break both algorithms simultaneously to recover the session key.

FIPS 203 1,568-byte ciphertext <1ms key exchange

Symmetric Encryption: AES-256-GCM

Once session keys are established, all media and data is encrypted with AES-256-GCM. This is the same symmetric algorithm used in classical TLS, and it provides 128-bit security against quantum attacks (Grover's algorithm halves the effective key length, so AES-256 provides 128-bit post-quantum security). No performance difference versus classical encryption.

256-bit keys 128-bit PQ security Hardware-accelerated

Digital Signatures: ML-DSA-65 (Dilithium)

Every recording, transcript, and AI-generated summary is signed with ML-DSA-65 Dilithium (FIPS 204). The 3,309-byte signature covers the content, a SHA3-256 hash, creation timestamp, and session metadata. Signatures can be independently verified via the /api/pq/verify endpoint without accessing the original content.

Enabling post-quantum encryption requires a single parameter. V100 handles key exchange negotiation, certificate management, and signature generation automatically. No cryptographic expertise required.

create-pq-session.js

// npm install v100-sdk
import { V100 } from 'v100-sdk';

const v100 = new V100('YOUR_API_KEY');

// Create a post-quantum encrypted video session
const session = await v100.meetings.create({
  name: 'Classified Briefing',
  encryption: 'post-quantum',   // ML-KEM-768 + X25519 hybrid
  recording: true,             // AES-256-GCM + Dilithium signed
  transcription: {
    enabled: true,
    signed: true              // ML-DSA-65 transcript signature
  }
});

// Verify a recording's signature later
const verification = await v100.pq.verify({
  recordingId: session.recording.id,
  signatureId: session.recording.signatureId
});

console.log(verification);
// {
//   valid: true,
//   algorithm: "ML-DSA-65",
//   hash: "SHA3-256",
//   signatureBytes: 3309,
//   signedAt: "2026-03-28T14:30:00Z",
//   fipsCompliant: true
// }

Or use the REST API directly:

terminal

curl -X POST https://api.v100.ai/v1/meetings \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Classified Briefing",
    "encryption": "post-quantum",
    "recording": true,
    "transcription": { "enabled": true, "signed": true }
  }'

Use Cases

Post-quantum encryption is critical for any organization where recorded conversations have long-term sensitivity -- where a breach years from now would be as damaging as a breach today.

Defense and Intelligence

Classified briefings, contractor coordination, and intelligence sharing over video. NSA CNSA 2.0 requires post-quantum migration by 2033. V100 meets that requirement today. Dilithium signatures provide provable chain of custody for recorded briefings.

Legal Proceedings

Remote depositions, witness interviews, and privileged attorney-client communications. Recordings must remain admissible for decades. Post-quantum encryption ensures confidentiality for the entire retention period. Dilithium signatures prove recordings have not been tampered with.

Healthcare and Telehealth

Patient consultations containing PHI must be protected for the full HIPAA retention period (6 to 30 years). Classical encryption will be broken well within that window. V100's post-quantum encryption combined with a signed BAA provides complete coverage. See our HIPAA Video API page for full compliance details.

Zero Latency Impact

A common misconception is that post-quantum encryption is computationally expensive. In practice, the overhead is negligible. The ML-KEM-768 key encapsulation adds less than 1 millisecond to session setup -- a one-time cost that is invisible to participants. The symmetric AES-256-GCM encryption used for the media stream is hardware-accelerated and identical in performance to classical implementations.
