Overview

The Flash Protection Series is a suite of enhancements available for PUFcc and PUFrt, extending the Hardware Root of Trust to protect critical assets in the commodity flash. The Flash Protection Series can widen an SoC’s secure boundary based on our highly reliable PUF technology widely available across all major foundries.

Key features

  • PUFenc is designed to protect external flash memory and its stored assets.
  • The IP provides asset encryption, such as a learning model for AI or firmware for the chip with a local key from the PUF.
  • It adds an additional layer of security by avoiding using the global key, which is a shared key among ICs after the chip leaves the manufacturing floor.

Embracing a More Secure Era with TLS 1.3

TLS 1.3 offers attractive speed and security improvement benefits that are hard to ignore. The handshake phase was sped up by removing one or more roundtrips (back and forth messaging between client and server) in TLS 1.3 – with “or more” meaning that for certain cases, roundtrips can be entirely eliminated (0-RTT).

The Challenge of Automotive Hardware Security Deployment

A complete reinvention of the automotive industry is currently underway. Autonomous driving, connected vehicles, and the electrification of the powertrain all represent a once-in-a-generation shift in the manufacturing process.

Why Hardware Root of Trust Needs Anti-Tampering Design

The hardware root of trust (HRoT) provides the trust base (root key), hardware identifier (UID), hardware unique key (HUK), and entropy required for the secure operation of the entire chip and therefore is often the focus of hacker attacks. If the design can’t effectively resist attacks, hackers can easily obtain the secrets of the entire chip. Attackers can use the secrets to crack identity authentication and data encryption and steal product design know-how, causing application security problems.

TPM 2.0-Ready: Top Security with PUFcc

The rising security threats endangering our connected world, from the chip to the cloud, are among the biggest challenges facing us today. Microsoft recently addressed some of these concerns by mandating the inclusion of TPM 2.0 (Trusted Platform Module) in all devices running its latest Windows 11 operating system. I

Solving Chip Security's Weakest Link

With the invention of Physical Unclonable Functions (PUF), we can now create a unique, inborn, unclonable key at the hardware level. The natural follow-up question to this is, “but how do we protect this key?” It is like storing your key to secrets in a drawer, a surefire way to break the secure boundary and create vulnerabilities.
