From Hardware-Software Contracts to Industrial IoT-Cloud Block-chains for Security

In the era of smart factories, to embrace IoT devices attached to physical assets, we need to guarantee control and complete confidence in how the data they share are used. This work introduces hardware mechanisms to ensure security in terms of secure key and signature storage through RFID/NFC secure modules and an IoT infrastructure communicating over LoRaWAN in conjunction with Hyperledger Fabric for traceability and immutability. A practical implementation is presented and evaluated with an average throughput of more than 70 transactions/sec for 16 peers.
