Overview

What is QU3?

QU3 is a command-line client application that establishes quantum-safe secure communication with Multi-Compute Provider (MCP) servers. It uses NIST post‑quantum cryptography (Kyber KEM and SPHINCS+ signatures) to authenticate clients, encrypt payloads, and verify server attestations. Developers and operators who need post‑quantum security for MCP workloads can use QU3 to run inference, execute agent workflows, and update policies.

How to use QU3?

Install dependencies, configure config.yaml (optional), start the mock server (python -m scripts.mock_mcp_server), then run client commands from another terminal: generate keys with python -m src.main generate-keys, send a single inference with run-inference <model> <json_data>, chain models with run-agent "<modelA> -> <modelB>" <data>, or update a policy with update-policy --policy-file <file>. The client automatically fetches server public keys if not found locally.

Key features of QU3

Uses NIST PQC finalists Kyber-768 for key encapsulation and SPHINCS+-SHA2-128f-simple for signatures
Establishes secure sessions via a KEM handshake endpoint (/kem-handshake/initiate)
Encrypts all request/response payloads with AES-256-GCM derived via HKDF-SHA256
Provides CLI commands: generate-keys, run-inference, run-agent, update-policy
Includes a FastAPI mock server with endpoints for key exchange, inference, and policy updates
Comes with unit tests for cryptographic utilities, configuration, and client communication

Use cases of QU3

Run inference on a quantum‑safe MCP server while ensuring end‑to‑end encryption and authentication
Chain multiple models in a secure agent workflow, passing outputs as inputs with step‑by‑step reporting
Send encrypted and signed policy updates to a server to enforce access control rules
Test and develop PQC‑enabled MCP integrations using the included mock server
