Cross-Cluster Identity Federation with PQC Security

Securely authenticate microservices across Kubernetes clusters using Hybrid Post-Quantum Cryptography (PQC). Generate quantum-safe federated tokens with MicroStax.

How to Federate Identity Across Clusters

MicroStax provides a centralized Sovereignty and Identity Layer (Patent 13) designed for the post-quantum era. When an AI Agent or a microservice spanning multiple regions needs to cross-authenticate securely, you must request a Federated Token.

These tokens utilize Hybrid Post-Quantum Cryptography (PQC)—combining classic elliptic-curve signatures with quantum-resistant algorithms—to ensure your session remains secure even against future compute threats.

Generating the Token

The fastest way to generate an ad-hoc token for testing or local scripting is via the VS Code interface or the MicroStax CLI.

Option A: VS Code Command Palette

Press Cmd/Ctrl + Shift + P.
Run MicroStax: Federate Identity Token...
Select the target Environment or Cluster from the menu.
The token is instantly copied to your clipboard.

Option B: The CLI

Verify your current identity scope and generate a JWT scoped for a specific target cluster:

# Verify your current PQC identity integrity
microstax identity verify <your-current-token>

# Generate a federated token for a target cluster
microstax identity federate --service default --target stx-eu-west-cluster

Utilizing the Token

You can now inject this JWT into the Authorization: Bearer <token> header of your API requests.

[!IMPORTANT] Short-Lived by Design: Federated tokens are short-lived. For long-running service-to-service (S2S) communication, we recommend using the MicroStax Identity Controller to automate rotation within your mesh.
