’Chain of trust’ security solutions for IoT device identities

Eurotech Device Identities Life Cycle

Eurotech is collaborating with Infineon Technologies, Microsoft and GlobalSign to develop a ’chain of trust’ security solution for IoT device identities. The companies are working together to deliver zero touch provisioning for IoT applications, and to simplify large scale, secure roll outs of connected devices.

A new technology collaboration has a goal to deliver assurance by extending the secured device identity chain from the edge to the cloud. Eurotech is working with Infineon, Microsoft and GlobalSign to simplify large scale, secure roll outs of connected devices.

Building on industry standards, the solution starts the chain-of-trust at Infineon’s OPTIGA TPM (Trusted Platform Module) installed in all Eurotech IoT Edge gateways. As platform manufacturer, Eurotech extends this ‘trust’ to a secure Initial Device Identifier, an IEEE 802.1AR certificate-based identity that is cryptographically bound and uniquely assigned to the device. This identity attests the integrity of the platform supply chain and provides the necessary baseline for zero touch onboarding.

As part of this collaboration, Eurotech has worked with GlobalSign and Microsoft, with its IoT Identity Service security subsystem of the Azure IoT Edge, to extend the chain-of-trust to cloud connectivity. This is achieved through enrollment of additional local certificates confirming device ownership to a customer and using these identities for automatic provisioning of Azure IoT Hub operational identities by the Azure Device Provisioning service.

The solution reduces the complexity of embedding strong certificate identities in cloud connected device architectures. It delivers a blueprint for the management of standard-based digital identities over the life-cycle of the device from manufacturing, provisioning, maintenance and decommissioning.

“We are very proud of partnering with industry leaders Infineon, GlobalSign and Microsoft to lower the barriers of adoption of best practices for hardware-anchored digital device identities,” said Marco Carrer, CTO at Eurotech. “This partnership reflects Eurotech’s commitment to cybersecurity and supporting its customers to reduce device complexity and management.”

“IoT is changing the way businesses think and operate, allowing them to optimize existing processes and opening the door for new business models and revenue streams,” said Sam George, corporate vice president, Azure IoT at Microsoft Corp. “Streamlining the process of creating a chain of trust reduces the risk of supply chain tampering and device attacks that stem from compromised device identities. By helping to mitigate these risks, we’re enabling organizations to build more durable and resilient IoT solutions—to innovate on a foundation of trust.”

“Security remains the key enabler for cloud service adoption. The necessary level of protection can only be achieved by combining software security mechanisms with robust hardware-based security capabilities based on globally accepted industrial and IT security standards. A chain of trust from the node to the cloud using hardware based security anchors allows to securely identify each IoT and Edge device, to protect sensitive data as well as the integrity of the Cloud”, said Juergen Rebel, Vice President & General Manager Embedded Security at Infineon.

“Secure, zero-touch onboarding of IoT devices to the cloud is an important solution that realizes immediate value through its security and efficiency said Lancen LaChance, VP of IoT with GlobalSign. It’s a solid blueprint that benefits the broader IoT industry by providing a proven, best practice solution to a common IoT device identity management challenge. Our collaboration with notable experts Infineon, Eurotech and Microsoft has enabled the entire IoT industry to take one secure leap forward.”
