For data at rest, a hardware root of trust anchored in silicon provides that foundation upon which all device security is built. Similarly, MACsec security anchored in hardware at the foundational communication layer provides that basis of trust for data in motion.

However, in-vehicle networks are vulnerable to a number of security threats, including eavesdropping, denial-of-service attacks, man-in-the middle attacks, and unauthorized access. This white paper explores how MACsec provides an effective solution to address the security challenges faced by automotive Ethernet networks and how Rambus MACsec IP solutions can be deployed across a range of use cases.

Once sufficiently large quantum computers exist, traditional asymmetric cryptographic methods for key exchange and digital signatures will be broken. Many initiatives have been launched throughout the world to develop and deploy new quantum-resistant cryptographic algorithms, known as Post-Quantum Cryptography (PQC).

And to many, represent a paradigm change for chip designers and chip consumers alike. Rather than a traditional single piece of monolithic silicon with many functions and features, a chiplet contains one or a very limited set of functions and features. Multiple chiplets are then assembled into a MCM (multi-chiplet module). Chiplets can offer multiple advantages over monolithic silicon. Learn the advantage and challenges, along with recommendations for the industry’s successful deployment of heterogenous chiplets.

The National Institute of Standards and Technology (NIST) announced on February 7, 2023, that it had selected the ASCON algorithm to become the standard for Lightweight Cryptography. In this whitepaper, we will explore what lightweight cryptography is and why it is worth considering for specific Internet of Things (IoT) use cases.

Nowhere is this truer than in data centers. Rambus has long recognized the need for security designs in data centers, and the Caliptra initiative discussed in this whitepaper is a welcome step towards a widespread adoption of Root of Trust designs in SoCs. The Caliptra specification, released at OCP Global Summit 2022, is defined as a Root of Trust for Measurement (RTM). In this whitepaper, we will present how the Rambus RT-660 Root of Trust (RoT) core can be deployed for Caliptra use case scenarios as well as many other Root of Trust use cases.

In the past, electronics going into vehicle systems implemented flat architectures with isolated functions controlling various components of the power train and vehicle dynamics. However, to support the realization of Level 4 and Level 5 (L4/L5) autonomous driving, a massive restructure is underway. The software-defined vehicle, the automotive Ethernet, vehicle-to-everything (V2X) connectivity, and domain controller units are just some of the new technologies required to realize L4/L5 capabilities. Ensuring all these new systems are both functionally safe and secure from cyberattacks is mission critical.
