Rambus Accelerates Automotive SoC Design with ASIL-B Certified Embedded Hardware Security Module

Rambus Inc. (NASDAQ: RMBS), a premier chip and silicon IP provider making
data faster and safer, today announced that the Rambus Root of Trust RT-640
Embedded Hardware Security Module (HSM) has received Automotive Safety
Integrity Level B (ASIL-B) certification per the ISO 26262 international
standard. Certified ASIL-B compliance is a critical requirement for
automotive manufacturers and their suppliers to ensure vehicle systems meet
necessary safety levels. As Advanced Driver Assistance Systems (ADAS) become
increasingly ubiquitous, it is imperative that vehicle electronic systems
and data be protected from cyberattack and system malfunction. By
integrating the Rambus RT-640 Embedded HSM, automotive SoC makers are able
to accelerate the process of achieving functional safety requirements with
proven, certified security IP.

“Increasingly sophisticated automotive systems must be both functionally
safe and resilient to cyberattack”

“Increasingly sophisticated automotive systems must be both functionally
safe and resilient to cyberattack,” said Neeraj Paliwal, general manager of
Security IP at Rambus. “With the Rambus RT-640 Embedded HSM, automotive
manufacturers get the best of both worlds: robust cybersecurity anchored in
hardware with the assurance of ASIL-B functional safety. We have already
achieved multiple design wins for the RT-640 across the globe, and it has
tremendous traction in the new centralized automotive architecture across
ADAS and sensors such as cameras, lidar and radar.”

Rambus is the leading supplier of security IP with the industry’s broadest
portfolio of solutions. With nearly 200 design wins in the past three years,
Rambus has proven security IP solutions for every application from consumer
IoT to mission-critical defense electronics. With certified solutions such
as the RT-640 Embedded HSM, chip and device makers can implement
state-of-the-art security, meet industry-specified requirements, and reduce
time to market.

Ensuring Functional Safety with ISO 26262 ASIL-B

Specified under ISO 26262, ASIL-B is a risk classification defined for
functional safety of road vehicles. ASIL levels are assigned by performing
risk analysis of potential hazards by examining various risk parameters such
as severity, exposure and controllability of the vehicle operating scenario.
In addition to the RT-640 HSM ASIL-B certification, the Rambus hardware and
software development organizations have demonstrated to have the
qualification, knowledge, and expertise required for the automotive industry
and therefore have been certified to operate in accordance with ISO
26262:2018 standard ASIL-B for development and support processes.

While developing ADAS, automotive electronics makers are building complex
SoCs, replacing discrete secure processor elements with ISO 26262-certified
synthesizable IP and software. The Rambus RT-640 is the first programmable
automotive grade Hardware Root of Trust IP solution on the market to reach
this certified status. Customers can integrate the RT-640 as-is and focus on
their own automotive security application without affecting the RT-640
certificate.

Integrated into an automotive SoC, the ASIL-B certified RT-640 silicon IP
design provides powerful cryptographic functions, state-of-the-art safety
mechanisms and anti-tamper technologies to protect critical automotive
electronics and data. This robust cybersecurity solution has been certified
by TÜV-SGS 26262 ASIL-B functional safety. The ASIL-B certificate guarantees
that all safety mechanisms are implemented and verified correctly, meet and
exceed the required safety integrity levels and are supported with the ISO
26262 required evidence.

The certified RT-640 Embedded HSM key features include:

Fully programmable, purpose-built security processor with hardware enforced
security and privilege levels
High-performance cryptographic accelerators for RSA, ECC, AES, HMAC and
SHA-2
NIST SP 800-90 compliant random bit generator
Hardware enforced security with state-of-the-art protection from side
channel and tampering attacks
ASIL-B safety mechanisms in the HW and SW implementation
