Abstract
Presented are systems, devices, and methods for reliably authenticating asymmetric cryptography-based ICs based on Physically Unclonable Functions (PUFs) that are immune to reverse engineering. Various embodiments of the invention enhance the level of security in IC architectures without the need to connect to a remote certification authority, thereby, eliminating shortfalls associated with online authentication. Certain embodiments accomplish this by using a PUF-generated secure private key that need never be output by or exported from the PUF.
