Building a Secure IoT Device - Ashutosh Kumar Singh, Arm

Building a secure connected device is a complex challenge. - Provisioning of a device requires handling of secrets. While creating a ‘physically secure’ facility is an accepted way of securely provisioning a device, this doesn’t scale very well in a globally distributed supply chain model- In a multivendor (hardware and software vendors) scenario, mutual trust needs to be minimized- The integrity of the system (hardware/software) needs to be guaranteed- Devices need to be able to support secure connectivity- Cloud entity must be able to ‘attest’ the device’s current status to be able to decide the ‘quality of service’ it should offer to a device- Firmware must be updatable to mitigate newly discovered threatsThis talks elaborates on these challenges and explains the steps involved in building a secure connected device. It also covers how these challenges are addressed in the context of Platform Security Architecture(PSA) and Trusted Firmware M project.
