Securing Automotive Ethernet Connections With MACsec

Zonal architecture in automotive design has become common in recent years in response to the increasing complexity of in-vehicle electrical systems. Automotive Ethernet is used to connect sensors and actuators to zonal gateways in ADAS (Advanced Driver Assistance Systems) enabled vehicles. With multi-gigabit links, it further connects zonal gateways to the central compute units that handle ADAS... » read more

Securing Automotive Ethernet With MACsec Silicon IP

In today’s cars, the Ethernet standard is the go-to solution for connecting zonal gateways to the central compute units that handle ADAS functionality. However, in-vehicle networks are vulnerable to a number of security threats, including eavesdropping, denial-of-service attacks, man-in-the middle attacks, and unauthorized access. This white paper explores how MACsec provides an effective sol... » read more

100G Ethernet At The Edge

The amount of data is growing, and so is the need to process it closer to the source. The edge is a middle ground between the cloud and the end point, close enough to where data is generated to reduce the time it takes to process that data, yet still powerful enough to analyze that data quickly and send it wherever it is needed. But to make this all work requires faster conduits for that data i... » read more

Protecting High-Speed Network Traffic With MACsec

By Dana Neustadter and Jerry Lotto There is an ever-increasing demand for bandwidth, driven by an exponential growth in the number of devices connected to the cloud and a broadening variety of sensors, applications, and services, resulting in an explosion of data traffic. This in turn, drives the proliferation of high bandwidth interfaces such as Ethernet, PCIe/CXL, and DDR to sustain faster... » read more

Industry Adoption Of Line-Rate Network Security Using MACsec

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 infrastructure. This article will explore Media Access Control security (MACsec) and how it can be used to provide foundational level network security for a wide range of app... » read more

800G Ethernet MACsec Integration And Verification

Ethernet is the interconnect technology of choice for a wide range of applications including (but not limited to) data centers, wireless backhaul, automotive, artificial intelligence (AI), and many other use cases. It is ubiquitous. As bandwidth requirements continue to scale to ever-dizzying heights due to the proliferation of data-intensive applications, developing, integrating, and validatin... » read more

Securing ADAS At The Chip Level

The advent of ADAS, Advanced Driver Assistance Systems, is making a dramatic impact on new vehicles. It provides many helpful functions such as automotive night vision, forward collision warnings, collision avoidance, and lane departure warnings. In order to operate, ADAS requires the computerization of most of the functions of the vehicle. This results in from 50 to over 100 electronic control... » read more

MACsec Explained: Securing Data in Motion

For end-to-end security of data, it needs to be secured when at rest (processed or stored in a device) and when in motion (communicated between connected devices). For data at rest, a hardware root of trust anchored in silicon provides the foundation upon which all data security is built. Similarly, for data in motion, security anchored in hardware at the foundational communication layer prov... » read more

Secure TSN Ethernet With MACsec Is Now Possible

For end-to-end security of data, it must be secured both when at rest (processed or stored in a 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 data security is built. Applications, OS, and boot code all depend on the root of trust as the source of confidentiality, integri... » read more

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. ... » read more
