The Rambus Root of Trust RT-1660 is a fully programmable, FIPS 140-3 compliant root-of-security core offering security by design for U.S. Defense mission-critical applications. The RT-1660 protects against a wide range of hardware and software attacks with state-of-the-art anti-tamper security techniques. U.S. Defense hardware requires the highest security protections due to sensitive information being stored and processed. The RT-1660 is a military grade security co-processor, built on a custom-designed 32-bit RISC-V architecture, along with dedicated, cryptographically secure memories.
The RT-1660 offers superior tamper resistance through the implementation of Differential Power Analysis (DPA) countermeasures and state-of-the-art fault injection attack (FIA) protections. The RT-1660 implements DPA and FIA protected AES, RSA, and ECC cryptographic accelerator cores. The RT-1660 provides HW implementations of a NIST SP800-90a/b/c compliant TRNG (true random number generator), Public Key Engine (RSA up to 8192 bits and ECC up to 521 bits), AES (all modes), HMAC and SHA-2/-3 crypto accelerators. The RT-1660 core is FIPS 140-3 CAVP/CMVP compliant. It is the ideal choice for chip and system architects designing FPGA and ASIC solutions for applications requiring the highest level of security.
How the Root of Trust Works
While built upon a RISC-V architecture, the 32-bit CPU in the RT-1660 is a custom implementation designed specifically for security use cases. Rambus employed over 20 years of device security experience to build a security co-processor providing the highest levels of siloed and layered security. The RT-1660 is designed for integration into military and government ASICs and FPGAs, offering secure execution of authenticated user applications, tamper detection and protection, and secure storage and handling of keys and security assets.
The Root of Trust offers 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 Root of Trust RT-1660 supports all commonly deployed host SoC processor architectures, including ARM, RISC-V, x86 and others.
Deep Anti-Tamper Experience
As the inventor and pioneer of DPA and an acknowledged leader in device security, Rambus is uniquely qualified to provide anti-tamper solutions for the most stringent requirements. Rambus technologies protect more than 9 billion chips per year, and as a US-based, independent company, Rambus has the experience and pedigree to be the solution provider of choice. Rambus has for more than 20 years supplied solutions for government and defense applications, including anti-tamper cores, software libraries, and testing workstations.
