Secured Global Time Synchronization in automotive

Secured Global Time Synchronization (SGTS) ensures trustworthy time distribution across CAN, FlexRay, and Ethernet networks. Introduced in Classic AUTOSAR R22-11, it provides the robust synchronization required for Software Defined Vehicles (SDVs). SGTS safeguards against false timing, accuracy loss, and Denial of Service (DoS) attacks through cryptography, freshness value management, and credential management.

Benefits
