Putting security first with an embedded secure core
Rambus’ security first method develops the most advanced secure compute processors. The CryptoManager Root of Trust secure processor is siloed from the main processor, supporting isolated cryptographic security processes.
The RISC-V Foundation’s executive director, Rick O’Connor, commented, “The Meltdown and Spectre flaws revealed a new class of vulnerabilities as common processors employ acceleration techniques like speculative execution to improve processing performance. With solutions like the Rambus CryptoManager Root of Trust, the extensible RISC-V ISA enables developers to build connected products with a fundamentally more robust approach to security.”
Programmable hardware-based root of trust core enables end-to-end security: chip-to-cloud-crowd
By establishing the trust chain early in the silicon manufacturing
process, a security core can enable trusted provisioning and robust
auditing of security-related activity throughout all phases of the chip
lifecycle. The CryptoManager Root of Trust offers the primary processor
a full array of security services, such as secure boot and runtime
integrity checking, remote authentication and attestation, and hardware
acceleration for symmetric and asymmetric cryptographic algorithms. The
CryptoManager Root of Trust creates a secure foundation for Rambus’
comprehensive CryptoManager suite of solutions, which also includes the CryptoManager
Provisioning Infrastructure and
Additional key benefits of the CryptoManager Root of Trust include:
Design Freedom: The open RISC-V instruction set architecture
Rambusto design a custom processor without microarchitecture constraints, enabling a security first design. The CryptoManager Root of Trust is purpose-built to be safe and independent from general processing, offering a smaller and simpler approach without sacrificing security. This provides customers the opportunity to better design and better validate their products.
- Siloed: The CryptoManager Root of Trust is a fully user-programmable processor specifically designed for security use andphysically separated from the primary processor with dedicated secure memory. Siloing allows the hardware Root of Trust to function in a known secure state, without allowing unintended access to secure functions through software backdoors.
Layered Security: The root of trust is designed with multiple
security layers. A small, ultra-secure nucleus builds outwards to less
secure sections. The less secure sections can only access higher
levels of security with hardware-based permissions. The
RambusCryptoManager Root of Trust supports multiple roots of trust and gives the ability for various parties to use the core without exposing keys.
