Optimized cybersecurity for powerful on-vehicle computing platforms

This diagram illustrates the software architecture of an automotive System-on-a-Chip (SoC) platform, emphasizing security components and their integration. It highlights various elements, including the Host (Application Processor), Real Time Host(s), and a Hardware Security Module (HSM). The Host runs a hypervisor managing virtual machines for Adaptive and User Space AUTOSAR. The Trust Zone incorporates a Trusted Execution Environment (TEE) alongside Classic AUTOSAR. The HSM Firmware serves as a Trust Anchor. Security components from ESCRYPT CycurSoC for both TEE and HSM are also indicated. — While supporting open and standardized interfaces (for example SHE+, AUTOSAR Classic, and Adaptive), ESCRYPT CycurSoC is flexible and integrable with different embedded technology solutions, including virtual machines and various host environments.
