1. Automotive Networks • Electronic Control Units (ECU’s) • About 100 ECU’s in Premium Vehicles • Different Strength • Different Transmission Media • Bus Technologies (CAN, LIN, FlexRay, etc.) • Point-to-Point Connections (Ethernet) • Cross-Communication for Advanced Functions • Step-by-Step to Ethernet - Securing Santa‘s Sleigh - INET XMAS Presentation 11.12.2018 by Timo Häckel
1. Automotive Networks • Advantages of Ethernet • Simple and Efficient Communication Architecture • Availability of the Technology • High Bandwidth • But: No Real-Time Guarantees • Real-Time Extensions to Ethernet • Time-Triggered Ethernet (TTE - AS6802) • Audio Video Bridging (AVB - 802.1QBA) • Time-Sensitive Networking (TSN - 802.1Q) - Securing Santa‘s Sleigh - INET XMAS Presentation 11.12.2018 by Timo Häckel
1. Automotive Networks • Opening the Network to the Outside • Radio Communication • Cloud Connection • Car-to-X Communication • Current vehicles are vulnerable! https://www.youtube.com/watch?v=RZVYTJarPFs - Securing Santa‘s Sleigh - INET XMAS Presentation 11.12.2018 by Timo Häckel
