Building security in an SoC aiming to meet the goals set by the ARM Platform Security Architecture (PSA) is a complex matter. This is compounded by the complexity of modern-day SoCs comprising multiple processors, security domains and security levels. The Rambus root of trust provides a solid foundation for the SoC security architecture ticking ‘all the boxes’ for reaching the security goals, while offering extensive support for effective integration into a complex TrustZone-based SoC infrastructure.

Security Verification of Rambus’ CryptoManager Root of Trust by Tortuga Logic
The confidentiality and integrity of cryptographic key material is critical to maintaining system security. A hardware root of trust, such as the Rambus CryptoManager Root of Trust, is designed to securely generate, store, and employ cryptographic keys. Tortuga Logic has independently verified the policies surrounding access to keys stored within registers in the CryptoManager Root of Trust using its Radix™ pre-silicon security verification platform.
The Importance of Chiplet Security
Chiplets are gaining significant traction as they deliver numerous benefits beyond what can be accomplished with a monolithic SoC in a time of slowing transistor scaling. However, disaggregating SoCs into multiple chiplets increases the attack surface which adversaries can exploit to penetrate safeguards to data and hardware. With chiplets, the risks of hardware-based trojans and exploits such as man-in-the-middle attacks all rise. To realize the many benefits of chiplets, designers should use a design for security approach, and implement security safeguards anchored in hardware.
Secure Networking Basics: MACsec, IPsec, and SSL/TLS/DTLS
The MACsec, IPsec and SSL/TLS/DTLS protocols are the primary means of securing data in motion (communicated between connected devices). These protocols can be anchored in hardware or implemented in software as part of an end-to-end security architecture. This white paper provides fundamental information on each of these protocols including their interrelationships and use cases.
Hardware Security for AI Accelerators
Dedicated accelerator hardware for artificial intelligence and machine learning (AI/ML) algorithms are increasingly prevalent in data centers and endpoint devices. These accelerators handle valuable data and models, and face a growing threat landscape putting AI/ML assets at risk. Using fundamental cryptographic security techniques performed by a hardware root of trust can safeguard these assets from attack.
Protecting Safety, Revenue and Brand: Combating Counterfeit Semiconductors in the Automotive Supply Chain
The counterfeit market for semiconductors is real, sizable and growing. Industry analysts peg the current market for fake semiconductors at $75B. Counterfeit chips pose great risk to driver comfort and safety, to say nothing of the severe negative consequences they present to automaker revenues and brand. The good news is there are immediate and cost-effective measures available to secure the semiconductor supply chain and stop counterfeiters in their tracks.
