10 Different kinds of flashing Calibration / Code Parameter settings E.g on -> off Data set download Data set Flashing Application Bootloader, OS Elektrobit (EB)

11 UDS update programming Read data by Identifier Diagnostic session control extended session Routine Control Check Prog Precond. Control DTC Setting (-> Off) Comm. Control Disable Non-Diag.Comm. Diagnostic Session Control Prog.Session Security Access Request Seed Transfer Key Write data by Identifier -Write fingerprint Read ECU identification in oder to check HW/SW compatibility Switch to extended session as next steps are not allowed in default session Check preconditions e.g. motor off, battery V sufficient Disable trouble code storage Disable normal ECU communication Switch to the programming session Login procedure, depending on security level Write ID of tester to document programming Elektrobit (EB)

12 UDS update programming Routine control - erase memory Request download Transfer data Request transfer exit Routine control check memory and reprog. dependencies ECU Reset Comm. Control enable Non- Diag.Comm. Control DTC Setting Diagnostic session control Default session Erase flash memory Prepare ECU for download In a loop: Transfer data blocks to ECU End download often the actual flash is started now Verify and ensure consistency Restart the ECU Re-enable normal communication Switch on trouble code logging End of programming Elektrobit (EB)

17 EB Solution: Evolution versus Revolution Solution: Use established mechanisms and processes with smart extensions Client receives SW Update via online connectivity (e.g. OTA-DM) Connection is secured via established mechanisms Internally an onboard diagnostics tester is connected to other ECUs Benefits Only one specific OTA-DM Client needed Legacy ECUs can be updated as well as next generations ECUs Avoid introducing a completely new path that has to be secured OTA for existing architectures more efficient and faster Elektrobit (EB),

18 EB Solution The Smart Antenna A smart antenna will concentrate all wireless protocols in one place and secure the car infrastructure from the wireless access. Technologies: Linux/Autosar multi-core system Firewall between Linux and Autosar Update OTA enabled Secure connection to back-end system Ethernet connection to gateway Linux Hypervisor Autosar Elektrobit (EB) 2015

19 The real Challenge Obvious, but not the challenge: Download packages to the car, Variants and versions to be managed The real challenges are: Security & attack vectors Update distributed functions Dealing with power consumption Elektrobit (EB),

20 Security Solutions by EB With more than 10 years of experience in engineering security processes and solutions, we are the perfect partner for carmakers and Tier 1 suppliers when ECUs require a secure software base. Use Cases: Authentication Signature Flash protection Software-enabling (carmaker-specific or according to HIS) Anti-theft protection Mileage protection Secure on-board communication Data protection Support for cryptographic hardware, e.g., SHE and HSM Compression and decompression Benefit from: Deep expertise Standardized and efficient embedded cryptography architectures based on AUTOSAR, HIS-Standard and customerspecific software: EB s security solutions seamlessly integrate into EB tresos AutoCore Reliability Support during the entire software life cycle paired with comprehensive maintenance services: EB s security solutions are already on the road in millions of cars Elektrobit (EB),
