Abstract

Internet of Things (IoT) devices still miss in many cases an ability to prove their identity, verify configuration changes based on a solid root-of-trust or have a data confidentiality protection anchored in hardware. This paper describes how to bridge between service-level security functionalities and a deeply silicon-integrated security solution, which is part of a larger System-on-Chip (SoC) for the benefit of increased security. Such a bridging raises new demands regarding silicon manufacturing, the Secure Operating System design, and also the communication and management interfaces. This is because in comparison to a “classical” Trusted Platform Module (TPM), no dedicated security hardware is available. This article describes the Sytem-onChip security integration’s impact on increasing the security level of the IoT service layer. “Integrated” refers to a secure enclave, which is no longer located on a separate chip, because it is part of the SoC of a larger device together with many other components on the same piece of silicon e.g. application/modem-processor cores, integrated memory and high-bandwidth I/O interfaces. A further aim of this paper is to create awareness about the capabilities of SoC-integrated security functions so that they can be leveraged by software designers, who are usually not deeply familiar with hardware security.
