Alexis Bruneteau 1a42b4d83b feat: Implement blockchain-based election storage with cryptographic security
Elections are now immutably recorded to blockchain with:
- SHA-256 hash chain for integrity (prevents tampering)
- RSA-PSS signatures for authentication
- Candidate verification via SHA-256 hash
- Tamper detection on every verification
- Complete audit trail

Changes:
- backend/blockchain_elections.py: Core blockchain implementation (ElectionBlock, ElectionsBlockchain)
- backend/init_blockchain.py: Startup initialization to sync existing elections
- backend/services.py: ElectionService.create_election() with automatic blockchain recording
- backend/main.py: Added blockchain initialization on startup
- backend/routes/elections.py: Already had /api/elections/blockchain and /{id}/blockchain-verify endpoints
- test_blockchain_election.py: Comprehensive test suite for blockchain integration
- BLOCKCHAIN_ELECTION_INTEGRATION.md: Full technical documentation
- BLOCKCHAIN_QUICK_START.md: Quick reference guide
- BLOCKCHAIN_IMPLEMENTATION_SUMMARY.md: Implementation summary

API Endpoints:
- GET /api/elections/blockchain - Returns complete blockchain
- GET /api/elections/{id}/blockchain-verify - Verifies election integrity

Test:
  python3 test_blockchain_election.py

E-Voting System - Post-Quantum Cryptography

Système de vote électronique sécurisé avec cryptographie post-quantique hybride certifiée NIST FIPS 203/204.

🚀 Démarrer

# Lancer tous les services
docker-compose up -d

# Frontend: http://localhost:3000
# API: http://localhost:8000/docs
# Database: localhost:3306

🔐 Sécurité Post-Quantique

  • Signatures: RSA-PSS + ML-DSA-65 (Dilithium) - FIPS 204
  • Chiffrement: ML-KEM-768 (Kyber) + ElGamal - FIPS 203
  • Hachage: SHA-256 (quantum-resistant)
  • Approche hybride: Defense-in-depth

🔑 Clés Cryptographiques

  • Génération: Clés hybrides RSA + Dilithium + Kyber à l'inscription
  • Stockage: Base de données sécurisée
  • Signatures: RSA-PSS + Dilithium sur chaque vote
  • Chiffrement: ML-KEM-768 (Kyber)

📊 Endpoints API

  • POST /api/auth/register - Inscription avec génération de clés PQC
  • POST /api/auth/login - Authentification JWT
  • GET /api/elections/active - Élection active
  • POST /api/votes/submit - Vote signé avec signatures hybrides
  • GET /api/elections/{id}/results - Résultats
