IoT Beyond Connectivity Proof of Concept, by China Unicom – Enabling a Marketplace for Authenticated IoT Data image

China Unicom and digital-only bank WeBank have developed a way to authenticate data collected by IoT devices using eSIMs (a SIM card that can be remotely provisioned and programmed) and blockchain technologies. A blockchain service, provided by China Unicom, can store cryptographic hashes corresponding with data collected by IoT devices, while a financial blockchain is supported by WeBank can be used to support related payment services.

Designed to ensure stronger trust for IoT data, this new solution uses an eSIM in the IoT device to securely store blockchain related cryptography algorithms and cryptographic keys. When the eSIM is activated the cryptographic keys are provisioned, providing the ability to uniquely identify the source of the IoT data, secure from third party access. […]
