RT-630 Programmable Root of Trust
The Rambus RT-630 Root of Trust (formerly the CryptoManager RT-630) is a fully programmable FIPS 140-2 certified hardware security core offering security-by-design for cloud, AI/ML as well as general purpose semiconductor applications. It protects against a wide range of hardware and software attacks through state-of-the-art anti-tamper and security techniques.
As cloud and AI/ML applications evolve, device and system architects face a growing array of security threats. Across applications, one constant is the need for a hardware root of trust-based security implementation. The Rambus RT-630 is the ideal security core for these markets. It employs a custom 32-bit RISC-V siloed and layered secure co-processor, along with dedicated secure memories. The RT-630 also features a number of high-capability cryptographic accelerators such as AES (all modes), HMAC, SHA-2/-3 (all modes), RSA up to 8192 bits, ECC up to 521 bits, and a NIST-compliant Random Bit Generator. Additional algorithms such as SHA-3, Poly1305 & ChaCha and OSCCA SM2-3-4 are available as optional HW crypto accelerators. Satisfying use cases such as identity management, attestation, and secure boot, the RT-630 is ideally suited for cloud and AI/ML applications where FIPS 140-2 and 140-3 compliance is required and security is a priority.

Product Brief
Security in the ARM Ecosystem
Building security in an SoC aiming to meet the goals set by the ARM Platform Security Architecture (PSA) is a complex matter. This is compounded by the complexity of modern-day SoCs comprising multiple processors, security domains and security levels. The Rambus root of trust provides a solid foundation for the SoC security architecture ticking ‘all the boxes’ for reaching the security goals, while offering extensive support for effective integration into a complex TrustZone-based SoC infrastructure.How the Root of Trust Works
The Root of Trust is an independent hardware security co-processor design for integration into semiconductor devices, offering secure execution of user applications, tamper detection and protection, and secure storage and handling of keys and security assets. The Root of Trust offers chipmakers a siloed approach to security; while located on the same silicon as the main processor, the secure processing core is physically separated. A layered security approach enforces access to crypto modules, memory ranges, I/O pins, and other resources, and assures critical keys are available through hardware only with no access by software. The Rambus Root of Trust supports all common main processor architectures, including ARM, RISC-V, x86 and others.
The Rambus Root of Trust supports multi-tenant deployments by offering true multiple root of trust capabilities. Each individual secure application can be assigned its own unique keys, meaning permissions and access levels are set completely independent of others. Secure applications are siloed from each other, ensuring the best approach to security. OEMs can determine access levels and permissions for each and all processes operating within the secure processor.
Dedicated FPGA configuration
The RT-630 is available in a FPGA configuration, targeting to be synthesized in programmable logic. This configuration is designed to map optimally (for max utilization and max frequency) into an FPGA fabric and connect either to on-board or external CPUs. In addition, the design is expanded with an additional OTP emulation model to overcome the lack of (or limitation of) true nonvolatile one-time programmable memory in certain FPGA families. This module allows storing secure assets in external flash in a secure way.
Secure Applications
Included with the RT-630 Hardware Root of Trust are a series of standard secure applications (“containers”) to speed development, including secure boot, identity management, HSM reference, and others. A container development kit (CSDK) is also included to allow the development of custom containers for specific use cases.
The Road to Post Quantum Cryptography
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. Learn about our solutions and recommendations to ready customers for a post-quantum world.

Full Disk Encryption of Solid State Drives and Root of Trust
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.
