SecureIC PUF IP is a hardware intellectual property core that generates cryptographic keys and device identifiers using Physically Unclonable Functions (PUF) technology. The solution extracts unique keys from silicon by amplifying inherent physical variations and technological dispersions in semiconductor devices into digital signals. The PUF IP generates keys that are not stored in non-volatile memory but are extracted using helper-data, providing protection against reverse engineering and cloning attacks. The technology relies on the principle that exact physical properties of semiconductor devices cannot be replicated, making each device's output unique and unclonable. The solution supports multiple use cases including unique device identity generation, anti-tamper key protection, chip authentication via challenge-response protocols, firmware authentication for integrity verification, and per-device firmware encryption to prevent attack-one-break-all scenarios. Key properties include randomness for balanced bit distribution, steadiness for consistent response generation, diffuseness for varied outputs across challenge sets, uniqueness across devices, tamper resistance, and mathematical and physical unclonability. Security metrics include 128-bit entropy for AES-128 keys and configurable reliability levels such as 1 FIT for ASIL D automotive requirements. The technology is applicable across information security, IoT devices, automotive systems, healthcare devices, banking and finance, and government and military applications. The PUF IP operates across specified environmental corners through adaptive control mechanisms.
