Together with Intrinsic-ID, NXP will demonstrate PUF technology on a SmartMX2 test chip with Intrinsic ID's SESAMES-award winning SATURNUS secure cloud application.
These then arrange themselves in a completely random order, which is mathematically so difficult to replicate it's known as PUF (physically unclonable function).
Adding PUF technology significantly improves the chip's protection from reverse engineering attacks, as it removes the permanent presence of the digital encryption key on the device.
This fingerprint (aka Physically Unclonable Function, or PUF) is a byproduct of tiny errors in the fabrication process -- something chip makers usually try to minimize.
By integrating Intrinsic ID's PUF technology into its secure microcontroller SmartMX2, NXP significantly enhances the chip's security architecture and strengthens applications such as NFC-enabled mobile payment, electronic ticketing, and eGovernment and cyber security services.
