AI-Defined Vehicles Increase Pressure On Auto Ethernet Reliability
By Liz Allan - 04 Jun, 2026 - Comments: 0

Key Takeaways: For AI-defined vehicles and onboard agentic AI, Automotive Ethernet provides high bandwidth for sensor data fusion, TSN ensures low latency and synchronization for real-time decisions, and MACsec secures the data link. Time-sensitive networking (TSN) is an essential protocol for ensuring 10BASE-T1S delivers data to where it needs to go on time. Still, it becomes less esse... » read more

Securing Terabit Ethernet For AI: Where MACsec, IPsec, And UET TSS Each Fit (And Why You Need More Than One)
By Vincent van der Leest - 04 Jun, 2026 - Comments: 0

As AI and HPC systems scale, the network has become both a critical enabler of performance and a rapidly expanding attack surface. The shift from rack-scale compute to cluster- and data center-scale AI infrastructure means that data is no longer confined to a single chip, board, or even system. Instead, it moves continuously across hundreds, or thousands, of endpoints, often at aggregate bandwi... » read more

World First: MACsec IP Receives ISO/PAS 8800 Certification For Automotive And Physical AI Security
By Pavithra Suriyanarayanan - 02 Apr, 2026 - Comments: 0

The automotive industry is entering the age of physical AI. Vehicles are rapidly transforming into intelligent, software-defined systems that perceive their environment, make real-time decisions, and act in the physical world. As autonomy expands and AI workloads move to the edge, one reality is becoming clear: If the data cannot be trusted, the AI cannot be trusted. Following independent... » read more

Securing Terabit Ethernet Networks With 1.6T MACsec Security Modules

The modern world is increasingly a digital one that encompasses the realm of electronic devices, the internet, and online platforms. This world is constantly evolving, driven by technological advancements and shaped by how humans interact with digital technologies. The key element of a digital world is information that needs to be collected, stored and processed in vast quantities. For many ... » read more

MACsec Fundamentals Securing Data in Motion: 2025
By Rambus - 03 Sep, 2025 - Comments: 0

For end-to-end security of data, it must be secured both when at rest (stored on a connected device) and when in motion (communicated between connected devices). For data at rest, a hardware root of trust anchored in silicon provides that foundation upon which all device security is built. Similarly, MACsec (Media Access Control) security anchored in hardware at the foundational communication l... » 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

Securing The Road Ahead: MACsec Compliant For Automotive Use
By Dana Neustadter - 05 Jun, 2025 - Comments: 0

Since the rise of connected and autonomous vehicles, the automotive industry has undergone a significant transformation. Modern vehicles are now equipped with advanced systems that communicate with each other and external infrastructures, enhancing the driving experience. However, this increased connectivity also brings heightened security risks. Unauthorized access to a vehicle’s systems can... » 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

Providing Line-Rate Network Security With MACsec
By Maxim Demchenko - 07 Nov, 2024 - Comments: 0

Network security protocols are the primary means of securing data in motion; that is, data communicated between closely connected physical devices or between devices and even virtual machines connected using a complex, geographically distributed infrastructure. This blog will explore Media Access Control security (MACsec) and how it can be used to provide foundational level network security for... » read more
