Synopsys Automotive MACsec Security Modules for Ethernet

Data security for Ethernet-connected devices is growing due to increasing sensitive data, new regulations, and advancements in cloud, mobile/5G, and automotive technologies. Media Access Control Security (MACsec) is the key Layer 2 protocol protecting network communications from threats like DoS and eavesdropping by establishing secure links.

Synopsys MACsec Security Modules use scalable AES-GCM cryptography to provide confidentiality, integrity, authentication, and replay protection for Ethernet traffic. These modules integrate seamlessly with Synopsys Ethernet MAC & PCS IP, supporting high data rates with low latency. By incorporating Synopsys MACsec Security Modules into Ethernet IP solutions, networking SoC designers can ensure end-to-end security for data in motion between Ethernet-connected devices.

Besides traditional MACsec solutions, Synopsys also offers the first automotive-certified MACsec for both functional safety (ASIL B) and cybersecurity (ISO/SAE 21434) compliance. This IP variant protects against random and systematic faults, where reliability and fault tolerance are paramount. It meets the stringent safety process and documentation requirements of ISO 26262, with ASIL D level of compliance for systematic faults, the highest safety integrity level for automotive applications.

Synopsys Automotive MACsec IP has been fully certified by SGS-TÜV for SAE/ISO 21434 cybersecurity process and ASIL B compliance.
