Sensor Networks

The Signpost is a modular city-scale sensing platform that provides power<br>and connectivity for a diverse set of sensing modules. Signpost is built<br>around Tock, and uses multiprogramming to let researchers build<br>applications and run experiments.

Security critical devices

Security critical devices, like TPMs and USB authentication fobs, are<br>actually multiprogramming environments running applications written by<br>different people. Tock guarantees that untrusted components can’t leak<br>secrets even if they are buggy or crash.

Wearables

Tock enables consumer IoT devices, like sports watches or fitness trackers,<br>that need to run for months on small batteries and low-memory<br>microcontrollers, to support third-party apps just like PC-grade<br>operating systems.
