From Blueprint to Production: How Rambus Brings Commercial-Grade Caliptra Security to AI SoCs

What happened

Rambus Inc. issued a press announcement ahead of the recent AI Infra Summit and was present at the summit to spotlight its new production-ready CryptoManager Root of Trust supporting the Caliptra specification. The solution introduces hardware-level security orchestration built directly around the unmodified open-source Caliptra core; by integrating a secure RISC-V processor, protected memory, and dedicated cryptographic accelerators alongside specialized drivers, it expands security visibility across the entire System-on-Chip (SoC). The stated cause is the gap between an open-source specification and production-ready, commercially deployable silicon: an open core typically lacks platform-wide security orchestration, and chip vendors otherwise shoulder all integration and schedule risks alone. The offering covers physical attack defense (side-channel analysis and fault injection countermeasures), cryptographic agility blending classical algorithms like AES, SHA, and RSA with emerging Post-Quantum Cryptography standards such as ML-KEM and ML-DSA, and readiness for certifications including FIPS 140-3, PSA, or SESIP.
