2. Secure Data Transmission

Ensuring secure and reliable data transmission is critical for Edma’s IoT-based energy tracking system. Secure transmission prevents tampering, ensures real-time updates, and safeguards sensitive energy data during its journey from smart meters to the blockchain.

Key Components of Secure Data Transmission

1. Encryption & Data Integrity

• Uses AES-256 encryption for securing transmitted energy data.

• Implements SHA-3 hashing to ensure data integrity before blockchain storage.

• Prevents man-in-the-middle (MITM) attacks and unauthorized data modifications.

2. Real-Time Communication Protocols

• MQTT (Message Queuing Telemetry Transport) for lightweight, real-time data streaming.

• TLS/SSL protocols for encrypted device-to-network communication.

• LoRaWAN & NB-IoT for long-range, low-power data transmission in remote energy sites.

3. Tamper-Resistant Data Relay

• Multi-node validation ensures that only authentic data reaches the blockchain.

• Uses edge computing to filter and preprocess data before transmission.

• Ensures redundancy through distributed ledger synchronization.

4. Integration with Blockchain Storage

• Transmitted data is hashed and recorded on-chain to guarantee immutability.

• Smart contracts validate incoming data before issuing Energy Tracking Tokens (ETT) and Clean Energy Coins (CLE).

• Decentralized storage solutions (IPFS, Arweave) are used for off-chain metadata storage.

How Secure Transmission Works in Edma

1. Smart meters encrypt and transmit energy data using TLS-secured MQTT.

2. Edge nodes validate and relay data to blockchain gateways.

3. Blockchain smart contracts verify and store hashes of recorded data.

4. Regulators and stakeholders access tamper-proof records for compliance verification.

By integrating end-to-end encryption, real-time protocols, and blockchain validation, Edma ensures secure, transparent, and tamper-proof energy data transmission within its decentralized ecosystem.
