I'm planing a project where a Single Board Computer (SBC)/Embedded PC etc. will be connected over HDMI to a monitor. The SBC should display a website through a browser in Kiosk mode.
The SBC is located in a place to which non-trusted people might gain access, therefore I'm looking for full-disk encryption and secure boot/verified boot.
I'm not sure which operating system I should use. I'm thinking of Android or Windows 10 IoT.
I know that the security features of GrapheneOS are depended on the hardware. Therefore only Pixel devices are supported, because they are the only devices with supported hardware. Do you know any SBC with similar secure hardware, where it's possible to get something similar as GrapheneOS in regards of security?
Has anyone had good experience with Windows 10 IoT?
