Mitigates security vulnerabilities like
Meltdown and Spectre
Rambus Inc. (NASDAQ: RMBS) today announced the availability
of the CryptoManager Root of Trust, a fully programmable hardware
security core built with a custom RISC-V CPU. The secure processing
core creates a siloed architecture that isolates and secures the
execution of sensitive code, processes and algorithms from the
primary processor. This mitigates the risk of critical
vulnerabilities like the recent Meltdown and Spectre security flaws
and allows designers to optimize the primary processor for high
performance, low power, or other characteristics while optimizing
security in the siloed core. The CryptoManager Root of Trust is an
embedded security core designed for applications from networking to
automotive to IoT.

Bret Sewell, SVP and general manager of the Rambus Security
Division, spoke to the key attributes of the division’s new secure
coprocessor: “The fundamental pillars of architectural design
freedom, secure processing siloed away from general processing, and
layered security with a root of trust designed for multiple
security layers, are unique to the CryptoManager Root of Trust
design and enable easy implementation with the highest levels of
protection. The CryptoManager Root of Trust also embeds features
that enable semiconductor manufacturers and device OEMs to insert
hardware keys, and enables IoT service providers to manage IoT
endpoints throughout their lifecycle in the field.”
IDC research director for IoT Security, Abhi Dugar, noted, “The
semiconductor industry faced some of its biggest security issues
this year with recent vulnerabilities, and the potential to
encounter additional security flaws will not go away any time soon
as more IoT devices enter the market. To address existing and new
threats, establishing trust at the hardware level will be critical,
and a secure siloed core can help ensure that this new generation
of devices can be protected from security flaws.”
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 CryptoManager IoT
Security Service.
Additional key benefits of the CryptoManager Root of Trust
include:
- Design Freedom: The open RISC-V
instruction set architecture (ISA) allowed Rambus to 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 and physically 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 Rambus CryptoManager Root of Trust
supports multiple roots of trust and gives the ability for various
parties to use the core without exposing keys.
