Authentication Apps Ensure IoT Device Security

Intrinsic ID introduces SPARTAN, a family of authentication solutions for IoT devices. SPARTAN enables device makers to ensure authentication based on digital identities derived from the silicon fingerprint of a chip that can be created at any point in the supply chain.


The first member offering, SPARTAN CLOUD, is embedded security software for IoT devices to establish a secure Transport Layer Security (TLS)-based connection to major cloud platforms, including Amazon Web Services, Microsoft Azure IoT Hub and Google Cloud Platform. It provides seamless integration with cloud-connected applications via a library based on the MQTT messaging protocol. Use cases include cloud-based data collection and processing from trusted IoT sensor nodes; smart home devices controlled from the cloud; smart city infrastructure; and smart health monitoring services.


Boasting advantages over traditional methods applied to similar use cases, SPATAN’s strong, SRAM PUF-derived chip identity means the chip cannot be cloned by copying non-volatile memory (NVM) information from one chip to another. No sensitive data is stored in NVM so the device’s private key is reconstructed on the fly from SRAM PUF. Since standard SRAM memory is used, the solution can be widely deployed in nearly any digital chip. The reconstructed private key is used directly by the Transport Layer Security (TLS) stack for client authentication towards the cloud server. The solution integrates seamlessly with the MQTT protocol library that is offered by the cloud provider to connect to its services. For more data, visit
