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
