PHYSICAL
INTEGRITY NODE
Tamper-evident edge hardware sealed at the busbar. Sensor fusion + PQC signing + secure uplink, the single physical root of trust for all Hepta-Validation data.
The PIN-SE v2 edge module.
The Physical Integrity Node is a tamper-evident, industrially sealed hardware unit installed directly at the busbar of each flex-load facility. It serves as the single physical root of trust for all Hepta-Validation sensor data.
Each PIN combines three core functions into one hardened enclosure: sensor fusion across all seven Hepta-V layers, post-quantum cryptographic signing, and secure uplink to the Hedera consensus layer.
Post-quantum security.
Every data packet signed at the PIN is protected against both classical and quantum computing attacks. The cryptographic stack is designed to remain secure for 25+ years.
CRYSTALS-Dilithium
NIST FIPS 204 standardized lattice-based digital signature scheme. Resistant to Shor's algorithm and all known quantum attacks. Selected as the primary post-quantum signature standard.
TPM 2.0+ Secure Enclave
Hardware-rooted key storage. Private keys never leave the silicon boundary. Attestation proves the module has not been tampered with since manufacture.
FIPS 140-3
U.S. federal cryptographic module validation. Ensures the entire signing pipeline meets government-grade security requirements for key management, physical security, and self-tests.
Seven steps from sensor to certificate.
Every DeliveryTag certificate passes through a rigorous 7-step pipeline, from initial detection at the PIN through to final issuance on Hedera. Each step must pass before the next can begin.
Detect
PIN sensor array fires a burst across all 7 Hepta-V layers. Raw telemetry captured at sub-second intervals from the busbar.
Curtail
If Mode B is active, PIN signals flex load to curtail. SCADA telemetry confirms the load reduction happened as instructed.
Verify
Cross-validate all 7 sensor layers against each other. Physical consistency check across electrical, thermal, magnetic, acoustic, spatial, emissions, and economic data.
Sign
CRYSTALS-Dilithium signature applied at the PIN's TPM 2.0+ secure enclave. The private key never leaves the silicon boundary. Signing latency < 10ms.
Anchor
Signed proof burst is submitted to Hedera Consensus Service (HCS) topic. aBFT consensus provides deterministic timestamp and sequence number. Finality in ~4 seconds.
Audit
Hedera Guardian policy engine validates schemas, verifies PQC signatures, pairs with EnergyTag GC (gc_ref), and runs the continuous verifier-readiness check.
Issue
DeliveryTag token minted on Hedera Token Service (HTS). 1 token = 1 MWh. Metadata anchors back to the full HCS proof chain. Transferred atomically to buyer.
Why post-quantum now?
Energy infrastructure has a 25-30 year operational lifespan. Certificates signed today must remain verifiable and non-repudiable for the lifetime of the assets they protect.
Quantum computers capable of breaking RSA and ECDSA are projected within 10-15 years. By deploying CRYSTALS-Dilithium at the hardware level today, DeliveryTag ensures that every signature ever created remains secure, even against future quantum adversaries.
