Accelerating The ASIL Journey For Chipmakers
By Adiel Bahrouch - 07 Aug, 2025 - Comments: 0

In the world of automotive innovation, safety is the silent partner riding shotgun. As vehicles evolve into complex, software-defined machines, the stakes for ensuring functional safety have never been higher. This is where ISO 26262 steps in—not as a mere checklist, but as a comprehensive framework that guides engineers through the intricacies of designing systems that won’t just perform, ... » read more

10Base-T1S Ethernet And The Use Of MACsec For Link Security
By Maxim Demchenko - 08 Jul, 2025 - Comments: 0

10Base-T1S (henceforth in this blog referred to as T1S) is a relatively new standard for a 10Mbit/s single-pair Ethernet over an unshielded, single-twisted pair that was introduced with the IEEE 802.3cg-2019 specification. It brings Ethernet technology into the low-cost, edge applications space, enabling connection of “edge nodes” (remote sensors, actuators, light controls, etc.) to a “he... » read more

Side-Channel Attacks On Post-Quantum Cryptography
By Mike Hamburg - 05 May, 2025 - Comments: 0

By Mike Hamburg and Bart Stevens Device security requires designers to secure their algorithms, not only against direct attacks on the input and output, but also against side-channel attacks. This requirement is especially notable for cryptographic algorithms, since they have a regular, well-understood structure, and the secrets they process often give access to much more information. Sid... » read more

Tailoring Root Of Trust Security Capabilities To Specific Customer Needs
By Bart Stevens - 03 Apr, 2025 - Comments: 0

The cybersecurity threat landscape is dynamic and rapidly evolving. Indeed, attackers are constantly finding new ways to exploit critical vulnerabilities across a wide range of applications and devices. Protecting data and devices requires secure processes running on systems and networks. A Root of Trust is the foundation on which all secure operations of a computing system depend. It contai... » read more

Accelerating Time To Market For The Software-Defined Vehicle With An Integrated Hardware Security Module Solution

The transformative shift towards the software-defined vehicle (SDV) continues as one of the greatest megatrends shaping the automotive industry. A new era of customer-centric mobility presents data-based revenue opportunities across the automotive value chain and ecosystem. However, this transition also presents many challenges, from managing increasingly complex hardware (HW) and software (SW)... » read more

Secure Networking With MACsec, IPsec, And TLS
By Bart Stevens - 06 Feb, 2025 - Comments: 0

As digital networks grow in complexity, securing data in transit has become a top priority. Cyber threats, ranging from man-in-the-middle attacks to large-scale data breaches, make strong encryption and authentication mechanisms essential. But network security is not a one-size-fits-all solution. Instead, it operates at different layers of the OSI model, with each layer offering unique protecti... » read more

Cryptography Does Not Equal Security
By Bart Stevens - 09 Jan, 2025 - Comments: 0

At Rambus, we often receive RFIs, RFPs and RFQs for security silicon IP cores to be used in our customer’s next semiconductor product. Such requests often contain a long shopping list of required cryptographic algorithms, their modes of operation, their key lengths or strengths and performance and sizing requirements. Depending on the target segment, additional requirements such as robustness... » read more
