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.

Revolution in Embedded Security

The growth of computing, graphics, neural processing power, communication bandwidth, and storage capacities have enabled amazing solutions. These innovations have created great value for society, and that value must be protected from exploitation by adversaries. This whitepaper explores many of these major technology changes and how Rambus’ security offerings help in tackling the new embedded security challenges of device and silicon manufacturers.

Anti-Tamper Benefits of Encrypted Helper-Data Images for PUFs

PUFs are mixed-signal circuits which rely on variations unique to a specific chip to self-generate a digital “fingerprint.” Most PUFs require a “helper-data” image that is generated during the initial digitization process, also known as Enrollment. Leveraging the chip-unique transformation function of PUFs and encrypted helper data, an unclonable challenge-response mechanism can be implemented that can distinguish authentic chips from perfect adversarial clones.
