Caliptra-enabled hardware security solution eyes AI SoCs

A production-ready root-of-trust and security orchestration solution provides dedicated hardware-level security for mission-critical data center and AI system-on-chips (SoCs). This enterprise-grade solution also accelerates design deployment with a complete hardware and software integration framework that includes dedicated drivers, APIs, and system-level security applications.
Rambus’ CryptoManager Root of Trust provides dedicated hardware-level security in an SoC design by combining a secure RISC-V processor, protected memory, secure key and data storage, cryptographic accelerators, and secure interfaces.
CryptoManager operates alongside an unmodified open-source Caliptra Project core, mediating interactions between the Caliptra Project core, the host processor, and other SoC components. This ensures security-sensitive operations remain within a protected boundary while extending trust across the wider platform.
CryptoManager’s root-of-trust and security orchestration are interoperable with Caliptra, an open-source security framework for silicon root of trust designed for integration into data center-class SoCs. Originally an Open Compute Project (OCP) initiative, it’s currently developed within the CHIPS Alliance.
Caliptra combines hardware, firmware, and specifications to provide a common foundation for device identity, measured boot, and attestation across CPUs, GPUs, AI accelerators, DPUs, networking devices, and other infrastructure components.
“As the Caliptra ecosystem gains momentum, organizations need a practical path to deploy scalable and supportable security solutions in demanding production environments,” said Simon Blake-Wilson, senior VP and GM of silicon IP at Rambus. “CryptoManager Root of Trust supporting the Caliptra specification provides the hardware, software, advanced protections and commercial support needed to accelerate deployment of differentiated enterprise-grade security that is interoperable with the Caliptra framework.”

CryptoManager supports classical, post-quantum, and regional cryptographic algorithms. It also provides advanced protections against side-channel and fault-injection attacks, as well as certification support for security standards such as FIPS 140-3 and SESIP.
Furthermore, CryptoManager employs specialized drivers and security applications to offer platform-level awareness, enabling security monitoring, policy enforcement, secure lifecycle management, and coordinated protection of critical system resources.
This platform-wide security awareness, combined with proven side-channel and fault-injection protections, facilitates cryptographic agility for a low-risk path to volume implementations of highly secure data center and AI semiconductor devices.
