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.
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.
CXL emerges as memory coherent fabric leader as GenZ Consortium transfers assets
In this 451 Research analysis, the report describes Compute Express Link Consortium’s acquisition of Gen-Z Consortium, seeking “to establish cache-coherent interconnects for processors, memory expansion and accelerators.” Read how this consolidation could positively affect both memory semantic protocols that enable high-speed connectivity to processors, accelerators and memory expansion technologies and the overall market.
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.
