Tillitis Key 1

Introduction

Tillitis Key 1 is a new kind of USB security token. All of its software, FPGA logic, schematics, and PCB layout are open source, as all security software and hardware should be. This in itself makes it different, as other security tokens utilize closed source hardware for its security-critical operations.

What makes the Tillitis Key 1 security token unique is that it doesn’t verify applications, it measures them, before running them on its open hardware security processor.

Each security token contains a Unique Device Secret (UDS), which together with an application measurement, and an optional user-provided seed, is used to derive key material unique to each application. This allows users to build and load their own apps, while ensuring that each app loaded will have its own cryptographic identity. The design is similar to TCG DICE. The Tillitis Key 1 platform allows for applications up to 64 KB.

The first implementation is the Tillitis Key 1: The Tillitis Key 1 PCB
