PUFlib

Portable, modular library for manipulating and using physically-uncloneable functions (PUFs).

Motivation

Trusted computing primitives generally consist of a TPM or other chip-set extensions, making trusted computing challenging on legacy or embedded platforms. PUFlib aims to alleviate those by providing a seal() and unseal() API that relies on one or more PUFs, tying the sealed data to that exact hardware. This project aims to both provide more PUF sources for greater hardware support.

Design

PUFlib is designed to be highly modular as PUFs are quite hardware-dependent. The core PUFlib aims to provide a consistent API for usage and multi-PUF source support.

Documentation

API functions are documented in the headers under include/. To compile this documentation into HTML for easy browsing, type make docs (requires Doxygen).

Implementing modules

See IMPLEMENTING.md under docs/ for information on how to implement new puflib modules.
