Tamper‑Proof Data & Granular Control for Connected DevicesIOT DevicesGrant each IoT device exactly the permissions it needs—verifiable, revocable, and auditable.
Why This MattersBillions of sensors, meters, and embedded controllers now make critical business decisions. When they send unauthenticated data or accept unsigned commands, a single exploit can falsify invoices, violate safety limits, or halt production lines. Organisations must know which device is talking, whether its data is genuine, and who is allowed to reconfigure it.Empeiria supplies the missing trust layer: verifiable device identities and credentials that travel with every datapoint or command, keeping interactions secure and fully traceable.

Drivers for change

Static X.509 certificates are hard to rotate and rarely scope permissions.
Message brokers and APIs seldom enforce fine‑grained device policies.
Emerging regulations (EU Data Act, NIS2, Medical Device Regulation) demand cryptographic proof of integrity and origin for operational data.

With Empeiria, devices can speak for themselves while you retain full control.

The Fix in 30 Seconds
number
Decentralised Identifier (DID)Each device receives a unique cryptographic ID.
number
Device CredentialA verifiable credential describes allowed topics, commands, and data schemas, plus expiry.
number
Continuous VerificationEvery message is checked by our Verifier microservice and rejected instantly if the credential is invalid or revoked.
Flagship Use Case – Tamper‑Proof Smart Meter
Scenario

A utility needs authenticated electricity readings but must never accept configuration commands from the meter.

Grant

Ops issues a credential: `{ "topic": "reading/energy", "rate": "15 min", "expires": "2026‑01‑01" }` via the Empeiria dashboard.

Send

The meter signs each reading and attaches the credential.

Verify

The backend validates the signature and policy in < 100 ms.

Revoke

If tampering is detected, the credential is revoked; further readings are rejected or quarantined.

Outcome

Reliable billing data and instant containment of compromised devices.

Additional Use Cases

Secure Firmware Updates

Only binaries signed by an issuer holding a Software‑Update credential are executed by the device.

Industrial Sensor Compliance

Sensors emit signed VCs for temperature, calibration, or inspection results, enabling automated quality audits and warranty proofs.

Pre‑Flight Assurance for Drones & AGVs

Each vehicle proves its software version and approved mission parameters before launch, blocking rogue payloads or routes.

Hospital Devices & Patient Safety

Infusion pumps and monitors log every dosage change or alarm under a Credentialed Clinician VC, producing an immutable treatment record.

Third‑Party Maintenance

External technicians receive time‑bound diagnostics credentials, isolated from production commands, and automatically expire when the job is done.

Cross‑Border Compliance Validation

Regulators verify device origin and conformity claims at import, using globally resolvable VCs to accelerate customs clearance.

Benefits
Business
  • Reduced Compliance RiskCryptographic evidence of origin fulfils NIS2, MDR, and sector mandates.
  • Fraud PreventionSigned meter and sensor data blocks spoofing and eliminates manual audits.
  • Device‑as‑a‑ServiceUsage‑metered credentials enable flexible billing and remote disablement.
  • Ecosystem ExpansionExternal device makers integrate safely without exposing core systems.
Technical
  • DevelopersSDK adapters for MQTT, CoAP, HTTP; reach a verified message in under 30 minutes.
  • Security & OperationsOne‑click credential revocation; hardware‑backed keys optional.
  • ArchitectureRuns beside existing TLS and OAuth setups; no downtime migration.
Get Started

1. Register the device in the dashboard to obtain its DID.

2. Issue a Device Credential with permitted topics or commands.

3. Send a signed message through the sample MQTT broker to see real‑time verification.

FAQ
Quuestion
How is this better than X.509 certificates?
Answer
Certificates prove identity but not intent. Empeiria credentials add signed policy—scoped, portable, and instantly revocable—without the overhead of a full PKI rollout.
Quuestion
What if a device goes offline?
Answer
Credentials can be cached and presented offline. Policies such as max age enforce freshness when connectivity returns.
Quuestion
Can I combine this with my current IoT platform?
Answer
Yes. Use our MQTT or REST gateways as policy enforcement points, or embed the Verifier as a sidecar in your cluster.
Quuestion
How fast is revocation?
Answer
Typically under one second, anchored on the Empe Blockchain.
Quuestion
Do I need secure hardware?
Answer
It helps, but is optional. The SDK supports TPM, HSM, or pure‑software keys, letting you phase in hardware when convenient.
