The Seven Properties of Highly Secure Devices

I've just noticed an [interesting piece of work from Microsoft last year](https://www.microsoft.com/en-us/research/publication/seven-properties-highly-secure-devices/) which both (a) identifies a minimum useful set of security properties for Internet-connected devices and (b) develops a working prototype with MediaTek to demonstrate how little change to an existing microcontroller is required to make this work. The selected set of properties feels about right: - **Hardware-based Root of Trust**: Does the device have a unique, unforgeable identity that is inseparable from the... (more)

I have therefore been meaning for a while to start a blog on these topics. [Recent events](https://en.wikipedia.org/wiki/Facebook_and_Cambridge_Analytica_data_breach) have finally given this project impetus enough to commence. The name [Panprivicon](/panprivicon) is a play on Bentham's panopticon and concisely expresses my desire to live in a world where each of us... (more)
