ZTT — Temporal Zero Trust Pack
Security isn't just about "Who".
It's about "When".
It's about "When".
Standard Zero Trust verifies identity, device, and location. **ZTT** adds the missing dimension: **Temporal Context**. By binding every action to a fleeting phase window, we make stolen credentials instantly perishable.
Replay-Proof
Capturing a signed request is useless. By the time an attacker tries to re-submit it, the temporal window has closed and the nonce is already in the horizon store.
Phase-Gated Validity
Define high-precision execution windows (e.g., ±2 seconds). If an action happens at the wrong phase, the gateway rejects it, even with a valid signature.
Stale Execution Prevention
Prevent "Store now, execute later" attacks. Credentials don't just expire; they are mathematically invalid outside their specific cycle and tick context.
Instant Revocation
Need to kill a session? Instead of complex CRLs, just let the window expire. ZTT provides natural, architectural revocation.
The ZTT Pipeline
ZTT transforms your API security from static to dynamic:
1. Challenge
Server issues a fresh temporal anchor.
2. Intent
Client signs payload + window + anchor.
3. Verify
Gateway checks Ticks, Cycle, and Nonce.
Why ZTT?
- Financial Services: Prevent fraudulent transaction replays and time-sensitive market exploitation.
- Critical Infrastructure: Ensure control commands (IoT) are executed exactly when they were intended, protecting against signal interception.
- Autonomous Agents: Enforce governance on AI tool calls, ensuring they operate within authorized coordination windows.
Implementation
ZTT is implemented via the **Timeverse Gateway** and the **Security Profile** spec. It works offline for verification once keys are pinned, making it ideal for high-availability environments.
