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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for authentication based on physically unclonable functions","description":"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.
