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.
The Road to Post Quantum Cryptography
Quantum computing offers the promise of tremendous leaps in processing power over current digital computers. But for the public-key cryptography algorithms used today for e-commerce, mobile payments, media streaming, digital signatures and more, quantum computing represents an existential event. Quantum computers may be able to break the widely used RSA and ECC (Elliptic-Curve Cryptography) algorithms in as little as days. Work on Post Quantum Cryptography (PQC) is well under way, but implementation will come with its own set of challenges. Rambus has solutions and recommendations to ready customers for a post-quantum world.
Data Center Evolution: From Pluggable to Co-Packaged Optics
A torrent of data traffic is growing at an exponential rate driven by applications including 5G, AI/ML, video streaming, online gaming, ADAS and more. Handling this data traffic are hyperscale data centers that have grown to over 500 in number worldwide with a third as many in the pipeline. To scale computing resources to the growing data demands, hyperscale data centers deploy fiber optics throughout to provide the needed bandwidth and manage the power. Pluggable small form-factor optical modules have scaled the optical connections from 50G to 400G over the past two decades. With the evolution to 800G Ethernet and beyond, new architectures including co-packaged optics can enable the desired performance while keeping power consumption within the desired envelope.
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.
From Data Center to End Device: AI/ML Inferencing with GDDR6
Created to support 3D gaming on consoles and PCs, GDDR packs performance that makes it an ideal solution for AI/ML inferencing. As inferencing migrates from the heart of the data center to the network edge, and ultimately to a broad range of AI-powered IoT devices, GDDR memory’s combination of high bandwidth, low latency, power efficiency and suitability for high-volume applications will be increasingly important. The latest iteration of the standard, GDDR6 memory, pushes data rates to 18 gigabits per second and device bandwidths to 72 gigabytes per second.
