Portable, modular library for manipulating and using physically-uncloneable functions (PUFs).
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.
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.
API functions are documented in the headers under
