Overview

Designed to be integrated in power and space-constrained SoCs or FPGAs, the RT-131 Root of Trust (formerly VaultIP) is a FIPS 140-3 compliant hardware core that guards the most sensitive assets on chips and establishes the foundation for platform security.

Featuring a firmware-controlled architecture with dedicated secure memories, the RT-131 hardware Root of Trust provides a variety of cryptographic accelerators including AES, SHA-2, OSCCA SM2/SM3/SM4, RSA and ECC. Ideal for power and space-sensitive applications like Chinese IoT server, gateway and edge devices, the RT-131 Root of Trust offers the best balance of size and performance available on the market.

The RT-131 offers a series of key security use cases ‘out of the box’, including:

  • Secure Boot assist to host CPU(s) and protection of key material
  • Secure firmware upgrade management for Host CPU
  • Lifecycle management support
  • Secure Debug support
  • Secure device authentication and identity protection

The RT-131 provides a secure asset store:

  • Only the RT-131 can manage, use and access the assets
  • The O/S and applications cannot access key values
  • Applications request asset use by reference
  • Enforces policies for access and use of keys and cryptographic functions
  • Key generation, derivation, storage and transport

Why Anti-tamper Sensors Matter: Agile Analog and Rambus Deliver Comprehensive Security Solution

If your device processes valuable data, controls a critical function, or connects to a wider network, it’s a target. Attackers don’t just try to break software; they increasingly physically tamper with hardware; probing, fault injecting, or opening enclosures to bypass protections and extract secrets. The consequences range from IP theft and fraud to orchestrated downtime across fleets of connected devices.

Side-Channel Attacks On Post-Quantum Cryptography

Device security requires designers to secure their algorithms, not only against direct attacks on the input and output, but also against side-channel attacks. This requirement is especially notable for cryptographic algorithms, since they have a regular, well-understood structure, and the secrets they process often give access to much more information.

Cryptography Does Not Equal Security

At Rambus, we often receive RFIs, RFPs and RFQs for security silicon IP cores to be used in our customer’s next semiconductor product. Such requests often contain a long shopping list of required cryptographic algorithms, their modes of operation, their key lengths or strengths and performance and sizing requirements.

Root of Trust: A Security Essential for Cyber Defense

Imagine a datacenter powering critical cloud services, silently compromised by a tampered chip inserted during manufacturing. In most cases, the malware would be practically impossible to remove and could persist across formats/reinstalls !
