Real-Time Ingress Verification

TAIV (Time-Aware Ingress Verification) is the deterministic freshness control that proves every accepted packet is unique, in-order, and on-time. No keys, no heuristics — just measurable physics-grade verification at line speed.

Overview

The RPF IoT Gate verifies every incoming packet deterministically before it enters a system. It checks identity, sequence and timing closure in real time, blocking spoofed, replayed or delayed traffic instantly.

TAIV (Time-Aware Ingress Verification) is the Gate’s core mechanism for temporal authenticity — proof that every valid packet is both new and structurally correct.

TAIV is the documented, reproducible control that fulfills the NIS2 and IEC 62443 requirements for ingress event freshness.

How it Works

Built on the Core-Lite Engine (CLE), the Gate computes a deterministic fingerprint for each packet as it arrives and compares it with recent event history. Packets meeting deterministic acceptance rules receive a verifiable “PASS” receipt; any replay, delay, or structural drift is rejected automatically.

TAIV defines invariants:

‖ Tᵢ – T₀ ‖ ≤ Δ — freshness within allowed drift
N ∉ cache_recent — no replay
Tᵢ > T_last(sender) — monotonic progression
Structural integrity check via Binder-compatible envelope

No encryption, tokens or probabilistic filters — only measurable, reproducible timing and sequence logic.

Technical Insight

IoT Gate operates on deterministic per-packet event analysis rather than statistical inspection. Each packet’s sequence, nonce and drift are verified as an independent deterministic event defined by TAIV. This process makes any replay or delay physically inconsistent and therefore impossible to accept.

Every PASS/FAIL decision is written to an append-only ledger that can be anchored through RPF Binder for compliance or external audit. The result is real-time, secret-free ingress verification that scales from industrial sensors to wide-area telemetry — all without changing protocols or existing encryption.
