Rambus Introduces RT-648: Bringing Arm-Based Root of Trust into the Automotive CSS Ecosystem

As the automotive industry transitions to software-defined vehicles (SDVs), security architectures must evolve from discrete features into integrated, platform-level capabilities. The next generation of automotive SoCs requires not only stronger security, but a more standardized and extensible foundation that aligns with broader silicon ecosystems. Rambus is addressing this need with the introduction of the automotive-grade CryptoManager RT-648, which is the company’s first embedded Hardware Security Module (eHSM) built around an Arm® processor and designed for pre-integration into the Arm Compute Subsystem (CSS) ecosystem.

MACsec Explained: Everything You Need to Know

MACsec (Media Access Control Security) is an Ethernet security standard that encrypts and authenticates data in motion at Layer 2 of the OSI model, protecting traffic as it moves between directly connected devices. In this blog, we’ll explore what MACsec is, how it works, how it compares to higher-layer security approaches, and why it is essential for modern Ethernet-based systems.
