After a quick review of recent IOT security debacles of past years, and more recent progress toward IoT Security by organizations such as the AllSeen Alliance, Open Connectivity Foundation, and the Industrial Internet Consortia, this talk will provide a developer-oriented deep dive on a new protocol developed in collaboration between ARM and two Global 2,000 companies along with other stakeholders. This new protocol aims to make it easier for developers to leverage hardware-backed security. Hardware-backed security comes in many forms, TPM, TEE, HSM SOC, ASIC and more. The protocol is first demonstrated in a TEE context, but could relatively easily be applied to other hardware-backed security architectures.
