Heterogenous Integration – Chiplets

Chiplets are a growing trend within the semiconductor industry. 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.

Lightweight Cryptography: An Introduction

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.

Going Beyond the Requirements of a Root of Trust for Measurement with the Silicon-Proven RT-660 Root of Trust

The continuously evolving technology landscape and security requirements for systems present many challenges for device and silicon manufacturers. 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.

Rambus RT-640 Road to ISO26262 Certification

Modern vehicles incorporate an increasing number of complex integrated circuits. Failures in automotive systems can lead to damage to property, injury or loss of life. Ensuring the reliability of electronic systems is crucial, and the ISO26262 standard documents the requirements for determining automotive functional safety. This whitepaper details the process for how Rambus achieved the ISO26262 ASIL-B certification of the RT-640 hardware security module.

Post Quantum Cryptography is Coming

Quantum computing has made big advances in recent years and experts agree that quantum computers capable of breaking 2048-bit RSA or 256-bit ECC will be built – it’s just a matter of time. In this white paper, we discuss the security algorithms NIST has selected for Post Quantum Cryptography (PQC) and their instantiation in Rambus security products.

Navigating the Intersection of Safety and Security

Vehicle systems and the semiconductors used within them are some of the most complex electronics seen today. 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.
