An Identity, Security, and Governance Framework for autonomous agents

Secure messaging core using X25519, Ed25519, HKDF, and AEAD for encrypted communication, with versioned envelopes, replay protection, and encrypted local storage. Hybrid-ready, testable, and built as a cryptographic engine rather than a full chat app.

A cryptographically verifiable distributed time system, designed for systems that require trusted, monotonic, replay‑resistant time.

Containerisiertes Linux-Testbed für ein sicheres Satelliten-Boden-Segment mit vereinfachter Orbitmodellierung, HMAC-geschützter Telemetrie, Replay-Schutz und Security-Monitoring.

Deterministic execution boundary for AI systems enforcing signed approvals, replay protection, and cryptographic receipts.

Notes and guides for implementing x402 micropayments on APIs.

Permission kernel for AI agents: capability-based policies, call allowlists, TTL, instant revoke, modular validators — no approve(∞).

TSAPS v1.0: A Deterministic, Channel-Bound Transaction Protocol for Financial APIs. Features Stateless Pre-Verification (PVG) and Semantic Idempotency. Archived on Zenodo (DOI: 10.5281/zenodo.18821754).

PQC-sealed wire protocol for remote-control streams. ChaCha20-Poly1305 AEAD, configurable sliding replay window, Ed25519-signed consent ceremony with mandatory per-session fingerprint (HKDF-SHA-256). Pre-alpha (SPEC draft-03).

Provide secure, verifiable time synchronization using Byzantine fault tolerance and tamper-evident storage for distributed systems.
