The Internet of Things (IoT) consists of billions of embedded devices connected to the Internet. Secure remote management of many of these devices requires them to store and use long-term cryptographic keys. In this work we propose to protect cryptographic keys in embedded IoT devices using a Trusted Execution Environment (TEE) which is supported on many embedded platforms. Our approach provides similar protection as secure co-processors, but does not actually require an additional secure hardware element.
