Secure element reduces production steps in IoT device-to-cloud onboarding
The OPTIGA™ Trust M Express secure element from Infineon Technologies is designed to reduce manufacturing and onboarding complexity in IoT devices by delivering a pre-provisioned cryptographic identity that is ready for cloud authentication at first power-up.
Typical IoT device-to-cloud onboarding relies on a per-device identity provisioning process in which each secure element must be individually accessed during manufacturing to extract its certificate and register it with the product cloud. This approach introduces additional production steps, requires secure handling of identity data, and depends on accurate correlation between devices and certificates, increasing the risk of errors that may only be detected after field deployment.
OPTIGA Trust M Express addresses these limitations by shifting identity provisioning entirely upstream into Infineon’s certified and secured manufacturing facilities. Each secure element is delivered with a cryptographic identity already injected and protected throughout its lifetime. As a result, no secured ID injection, certificate readout, or per-device tracking is required during IoT device manufacturing.
Once integrated into the end product, IoT devices authenticate against certificates that are pre-registered in the cloud. The approach is complemented by Infineon’s CIRRENT™ Cloud ID platform, which manages certificate ownership and registration without exposing device credentials during manufacturing or logistics.
OPTIGA Trust M Express supports asymmetric and symmetric cryptographic operations, secure key storage, and protected communication over I2C. The secure element provides a hardware root of trust that spans manufacturing, onboarding, and field operation, while reducing production overhead compared to traditional secure-element provisioning workflows.
