## 🔐 Post-Quantum Cryptography (PQC)
|
||||
|
||||
### Implémentation Active ✅
|
||||
|
||||
- **ML-DSA-65 (Dilithium)** - Signatures post-quantiques (FIPS 204)
|
||||
- **ML-KEM-768 (Kyber)** - Chiffrement post-quantique (FIPS 203)
|
||||
- **RSA-PSS** - Signatures classiques (défense en profondeur)
|
||||
- **ElGamal** - Chiffrement classique (défense en profondeur)
|
||||
|
||||
**Code:** `/src/crypto/pqc_hybrid.py` (275 lignes)
|
||||
|
||||
### Mode d'utilisation
|
||||
|
||||
Le code PQC est prêt mais fonctionne en mode dégradé:
|
||||
- **Sans liboqs:** Uses classical crypto only (RSA-PSS + ElGamal)
|
||||
- **Avec liboqs:** Activate hybrid (RSA + Dilithium + Kyber + ElGamal)
|
||||
|
||||
#### Activer la PQC complète:
|
||||
|
||||
```bash
|
||||
# Option 1: Installation locale
|
||||
pip install liboqs-python
|
||||
|
||||
# Option 2: Docker avec support PQC
|
||||
# Éditer Dockerfile.backend pour ajouter:
|
||||
# RUN pip install liboqs-python
|
||||
# Puis: docker-compose up -d --build
|
||||
```

# 🔐 Cryptographie Post-Quantique - Documentation
|
||||
|
||||
## Vue d'ensemble
|
||||
|
||||
Le système de vote électronique utilise maintenant une **cryptographie post-quantique hybride** basée sur les standards **NIST FIPS 203/204/205**. Cette approche combine la cryptographie classique et post-quantique pour une sécurité maximale contre les menaces quantiques futures.
|
||||
|
||||
## 🛡️ Stratégie Hybride (Defense-in-Depth)
|
||||
|
||||
Notre approche utilise deux systèmes indépendants simultanément:
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────────────────────┐
|
||||
│ SIGNATURES HYBRIDES │
|
||||
│ RSA-PSS (2048-bit) + ML-DSA-65 (Dilithium) │
|
||||
│ ✓ Si RSA est cassé, Dilithium reste sûr │
|
||||
│ ✓ Si Dilithium est cassé, RSA reste sûr │
|
||||
└─────────────────────────────────────────────────────┘
|
||||
|
||||
┌─────────────────────────────────────────────────────┐
|
||||
│ CHIFFREMENT HYBRIDE │
|
||||
│ ElGamal + ML-KEM-768 (Kyber) │
|
||||
│ ✓ Chiffrement post-quantique du secret │
|
||||
│ ✓ Dérivation de clés robuste aux quantiques │
|
||||
└─────────────────────────────────────────────────────┘
|
||||
|
||||
┌─────────────────────────────────────────────────────┐
|
||||
│ HACHAGE │
|
||||
│ SHA-256 (Quantum-resistant pour préimage) │
|
||||
│ ✓ Sûr même contre ordinateurs quantiques │
|
||||
└─────────────────────────────────────────────────────┘
|
||||
```
|
||||
|
||||
## 📋 Algorithmes NIST-Certifiés
|
||||
|
||||
### 1. Signatures: ML-DSA-65 (Dilithium)
|
||||
- **Standard**: FIPS 204 (Finalized 2024)
|
||||
- **Type**: Lattice-based signature
|
||||
- **Taille clé publique**: ~1,312 bytes
|
||||
- **Taille signature**: ~2,420 bytes
|
||||
- **Sécurité**: 192-bit post-quantique
|
||||
|
||||
### 2. Chiffrement: ML-KEM-768 (Kyber)
|
||||
- **Standard**: FIPS 203 (Finalized 2024)
|
||||
- **Type**: Lattice-based KEM (Key Encapsulation Mechanism)
|
||||
- **Taille clé publique**: 1,184 bytes
|
||||
- **Taille ciphertext**: 1,088 bytes
|
||||
- **Sécurité**: 192-bit post-quantique
|
||||
|
||||
### 3. Hachage: SHA-256
|
||||
- **Standard**: FIPS 180-4
|
||||
- **Sortie**: 256-bit
|
||||
- **Quantum-resistance**: Sûr pour preimage resistance
|
||||
- **Performance**: Optimal pour signatures et dérivation de clés
|
||||

|
||||
|
||||
```python
|
||||
message = b"Vote électronique sécurisé"
|
||||
|
||||
# 1. Signer avec RSA-PSS classique
|
||||
rsa_signature = rsa_key.sign(message, PSS(...), SHA256())
|
||||
|
||||
# 2. Signer avec Dilithium post-quantique
|
||||
dilithium_signature = dilithium_key.sign(message)
|
||||
|
||||
# 3. Envoyer les DEUX signatures
|
||||
vote = {
|
||||
"message": message,
|
||||
"rsa_signature": rsa_signature,
|
||||
"dilithium_signature": dilithium_signature
|
||||
}
|
||||
|
||||
# 4. Vérification: Les DEUX doivent être valides
|
||||
rsa_valid = rsa_key.verify(...)
|
||||
dilithium_valid = dilithium_key.verify(...)
|
||||
assert rsa_valid and dilithium_valid
|
||||
```
|
||||
|
||||
## 🔐 Processus de Chiffrement Hybride
|
||||
|
||||
```python
|
||||
# 1. Générer un secret avec Kyber (post-quantique)
|
||||
kyber_ciphertext, kyber_secret = kyber_kem.encap(kyber_public_key)
|
||||
|
||||
# 2. Chiffrer un secret avec ElGamal (classique)
|
||||
message = os.urandom(32)
|
||||
elgamal_ciphertext = elgamal.encrypt(elgamal_public_key, message)
|
||||
|
||||
# 3. Combiner les secrets via SHA-256
|
||||
combined_secret = SHA256(kyber_secret || message)
|
||||
|
||||
# 4. Déchiffrement (inverse):
|
||||
kyber_secret' = kyber_kem.decap(kyber_secret_key, kyber_ciphertext)
|
||||
message' = elgamal.decrypt(elgamal_secret_key, elgamal_ciphertext)
|
||||
combined_secret' = SHA256(kyber_secret' || message')
|
||||
```

## 🚀 Utilisation dans le Système de Vote
|
||||
|
||||
### Enregistrement du Votant
|
||||
|
||||
```python
|
||||
# 1. Générer paires de clés hybrides
|
||||
keypair = PostQuantumCryptography.generate_hybrid_keypair()
|
||||
|
||||
# 2. Enregistrer les clés publiques
|
||||
voter = {
|
||||
"email": "voter@example.com",
|
||||
"rsa_public_key": keypair["rsa_public_key"], # Classique
|
||||
"dilithium_public": keypair["dilithium_public"], # PQC
|
||||
"kyber_public": keypair["kyber_public"], # PQC
|
||||
"elgamal_public": keypair["elgamal_public"] # Classique
|
||||
}
|
||||
```
|
||||
|
||||
### Signature et Soumission du Vote
|
||||
|
||||
```python
|
||||
# 1. Créer le bulletin de vote
|
||||
ballot = {
|
||||
"election_id": 1,
|
||||
"candidate_id": 2,
|
||||
"timestamp": now()
|
||||
}
|
||||
|
||||
# 2. Signer avec signatures hybrides
|
||||
signatures = PostQuantumCryptography.hybrid_sign(
|
||||
ballot_data,
|
||||
voter_rsa_private_key,
|
||||
voter_dilithium_secret
|
||||
)
|
||||
|
||||
# 3. Envoyer le bulletin signé
|
||||
vote = {
|
||||
"ballot": ballot,
|
||||
"rsa_signature": signatures["rsa_signature"],
|
||||
"dilithium_signature": signatures["dilithium_signature"]
|
||||
}
|
||||
```
|
||||
|
||||
### Vérification de l'Intégrité
|
||||
|
||||
```python
|
||||
# Le serveur vérifie les deux signatures
|
||||
is_valid = PostQuantumCryptography.hybrid_verify(
|
||||
ballot_data,
|
||||
{
|
||||
"rsa_signature": vote["rsa_signature"],
|
||||
"dilithium_signature": vote["dilithium_signature"]
|
||||
},
|
||||
voter_rsa_public_key,
|
||||
voter_dilithium_public
|
||||
)
|
||||
|
||||
if is_valid:
|
||||
# Bulletin approuvé
|
||||
store_vote(vote)
|
||||
else:
|
||||
# Rejeté - signature invalide
|
||||
raise InvalidBallot()
|
||||
```
|
||||
|
||||
## ⚙️ Avantages de l'Approche Hybride
|
||||
|
||||

|
||||
- Compromis d'un système ne casse pas l'autre
|
||||
- Sécurité maximale contre menaces inconnues
|
||||
|
||||
2. **Résistance Quantique**
|
||||
- Prêt pour l'ère post-quantique
|
||||
- Peut être migré progressivement sans cassure
|
||||
|
||||
3. **Interopérabilité**
|
||||
- Basé sur standards NIST officiels (FIPS 203/204)
|
||||
- Compatible avec infrastructure PKI existante
|
||||
|
||||
4. **Performance Acceptable**
|
||||
- Kyber ~1.2 KB, Dilithium ~2.4 KB
|
||||
- Verrous post-quantiques rapides (~1-2ms)
|
||||
|
||||
## 🔒 Recommandations de Sécurité
|
||||
|
||||
### Stockage des Clés Secrètes
|
||||
```python
|
||||
# NE PAS stocker en clair
|
||||
# UTILISER: Hardware Security Module (HSM) ou système de clé distribuée
|
||||
|
||||
# Option 1: Encryption avec Master Key
|
||||
master_key = derive_key_from_password(password, salt)
|
||||
encrypted_secret = AES_256_GCM(secret_key, master_key)
|
||||
|
||||
# Option 2: Separation du secret
|
||||
secret1, secret2 = shamir_split(secret_key)
|
||||
# Stocker secret1 et secret2 séparément
|
||||
```
|
||||
|
||||
### Rotation des Clés
|
||||
```python
|
||||
# Rotation recommandée tous les 2 ans
|
||||
# ou après chaque élection majeure
|
||||
|
||||
new_keypair = PostQuantumCryptography.generate_hybrid_keypair()
|
||||
# Conserver anciennes clés pour vérifier votes historiques
|
||||
# Mettre en cache les nouvelles clés
|
||||
```
|
||||
|
||||
### Audit et Non-Répudiation
|
||||
```python
|
||||
# Journaliser toutes les opérations cryptographiques
|
||||
audit_log = {
|
||||
"timestamp": now(),
|
||||
"action": "vote_signed",
|
||||
"voter_id": voter_id,
|
||||
"signature_algorithm": "Hybrid(RSA-PSS + ML-DSA-65)",
|
||||
"message_hash": SHA256(ballot_data).hex(),
|
||||
"verification_status": "PASSED"
|
||||
}
|
||||
```
|
||||
|
||||
## 📚 Références Standards
|
||||
|
||||

# Getting Started with Create React App
|
||||
|
||||
This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
|
||||
|
||||
## Available Scripts
|
||||
|
||||
In the project directory, you can run:
|
||||
|
||||
### `npm start`
|
||||
|
||||
Runs the app in the development mode.\
|
||||
Open [http://localhost:3000](http://localhost:3000) to view it in your browser.
|
||||
|
||||
The page will reload when you make changes.\
|
||||
You may also see any lint errors in the console.
|
||||
|
||||
### `npm test`
|
||||
|
||||
Launches the test runner in the interactive watch mode.\
|
||||
See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
|
||||
|
||||
### `npm run build`
|
||||
|
||||
Builds the app for production to the `build` folder.\
|
||||
It correctly bundles React in production mode and optimizes the build for the best performance.
|
||||
|
||||
The build is minified and the filenames include the hashes.\
|
||||
Your app is ready to be deployed!
|
||||
|
||||
See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
|
||||
|
||||
### `npm run eject`
|
||||
|
||||
**Note: this is a one-way operation. Once you `eject`, you can't go back!**
|
||||
|
||||
If you aren't satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
|
||||
|
||||
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
|
||||
|
||||
You don't have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
|
||||
|
||||
## Learn More
|
||||
|
||||
You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started).
