Abstract-We can expect the number of Internet of Things (IoT) devices to rapidly increase, in part due to the availability of low cost powerful hardware. These advances in hardware introduce a new class of computer -the commodity low-cost Single Board Computer (SBC); for example the Raspberry Pi. These devices are capable of running a full operating system and are accessible to non-technical users.In this paper we demonstrate the feasibility of using this class of computer to construct IoT devices without deep technical knowledge of embedded systems. Our IoT device is targeted at real world data collection and is the basis of a deployed device.We discover that although the existing SBC hardware on the market varies dramatically, much of it is very applicable to IoT scenarios. Generally their default out of the box configuration supports one or more Linux variants, highlevel programming languages and standard hardware libraries. They are very configurable and attractively priced -we predict a growth in using this class of computer particularly for IoT prototypes; disposable compute or low hardware volume scenarios.In the future we can expect hardware improvements and enhanced operating systems taking into account the issues surrounding IoT devices, such as SD card storage corruptions, power consumption and improved failure detection.

“…TI M-Shield [2] and ARM TrustZone [3], [4] are early examples, followed by newer architectures like the Intel SEP security co-processor [5] and Apple's "Secure Enclave" co-processor [6]. Business requirements such as the need to enforce digital rights management and subsidy locks, as well as regulatory requirements like 1 https://open-tee.github.io cloning-and theft protection have been the driving forces behind such large scale deployment [1]. Such requirements continue to appear: e.g., fingerprint scanners with hardware protection, hardware-backed keystores, and the recent "kill switch" [7] bill in California mandating that a mobile device must be capable of being rendered inoperable if it is stolen.…”

Abstract-Hardware-based Trusted Execution Environments (TEEs) are widely deployed in mobile devices. Yet their use has been limited primarily to applications developed by the device vendors. Recent standardization of TEE interfaces by GlobalPlatform (GP) promises to partially address this problem by enabling GP-compliant trusted applications to run on TEEs from different vendors. Nevertheless ordinary developers wishing to develop trusted applications face significant challenges. Access to hardware TEE interfaces are difficult to obtain without support from vendors. Tools and software needed to develop and debug trusted applications may be expensive or non-existent.In this paper, we describe Open-TEE, a virtual, hardwareindependent TEE implemented in software. Open-TEE conforms to GP specifications. It allows developers to develop and debug trusted applications with the same tools they use for developing software in general. Once a trusted application is fully debugged, it can be compiled for any actual hardware TEE. Through performance measurements and a user study we demonstrate that Open-TEE is efficient and easy to use. We have made Open-TEE freely available as open source 1 .This is the author's version of the article
