Mitigates security vulnerabilities like Meltdown and Spectre
SUNNYVALE, Calif. & SAN FRANCISCO--(BUSINESS WIRE)--
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.
