Designed to be integrated in power and space-constrained SoCs or FPGAs, the RT-121 Root of Trust (formerly VaultIP) is a FIPS 140-2 compliant hardware core that guards the most sensitive assets on chips and establishes the foundation for platform security.
Featuring a state-machine architecture with dedicated secure memories, the RT-121 hardware Root of Trust provides a variety of cryptographic accelerators including AES, SHA-2 and ECC, and region-specific SM2-, SM3, and SM4 accelerators. Ideal for power and space-sensitive applications and uses such as secure services and key management for the Chinese market, the RT-121 Root of Trust offers the best balance of size and performance available on the market.
The RT-121 offers a series of key security use cases ‘out of the box’, including:
The RT-121 provides a secure asset store:
The RT-121 Root of Trust is a silicon IP core developed to protect an SoC platform and its operation. It allows the SoC to boot securely and protects sensitive key material and assets. At its heart, its Secure Asset Store secretly generates keys and securely stores them. Fully featured, its cryptographic data plane associated to its DMA offloads the main CPU while never exposing secret data to the OS or the applications. It is designed to provide secure, energy efficient and accelerated security functions.
Readily deployable, the RT-121 Root of Trust is offered in off-the-shelf configurations, allowing a choice tailored to the needs of your application. Configurations differ by cryptographic accelerators contained and 3rd-party certification and standard compliance.
The RT-121 is part of the broad Rambus Root of Trust portfolio, which ranges from small, lightweight cores designed to protect IoT endpoints all the way to fully programmable Root of Trust cores designed to protect the most sensitive government/defense chips and automotive deployments requiring ISO-26262 certifications.
Quantum computing offers the promise of tremendous leaps in processing power over current digital computers. But for the public-key cryptography algorithms used today for e-commerce, mobile payments, media streaming, digital signatures and more, quantum computing represents an existential event. Quantum computers may be able to break the widely used RSA and ECC (Elliptic-Curve Cryptography) algorithms in as little as days.

File encryption, file system encryption and full disk encryption (FDE) are methods offered by the industry to allow users to protect their data stored on non-volatile storage devices, such as Solid State Disks (SSD). The main feature of FDE is to protect stored system and user date from unauthorized reading, writing, alteration, moving or rolling back. However, extended security features are key to securing FDE implementation.
