Objective
OEMs and Tier-1 suppliers across the USA, Germany, UK, and China are increasingly prioritizing cybersecurity in automotive ECU development to meet evolving standards such as ISO 21434, AUTOSAR SecOC, and OEM-specific security protocols. These challenges span secure boot processes, cryptographic integration, secure communication, and OTA update mechanisms. AVIN Systems was engaged as a strategic partner to support cybersecurity integration, compliance, and secure software lifecycle management across multiple ECU programs.
Solution
Requirement Analysis & Configuration
- Mapped cybersecurity requirements to AUTOSAR architecture for RADAR, BMS, and Alternator ECUs.
- Created structured templates for documenting security features such as Secure Boot, Key Management, and OTA update protocols.
- Facilitated traceability between cybersecurity requirements, design elements, and test cases, ensuring alignment with ISO 21434 and OEM standards.
- Supported teams with starter kits and configuration guides for implementing secure communication and bootloader features.
- Conducted gap analysis and reviews to identify missing security features and ensure compliance readiness.
- Enabled secure configuration of Ethernet Time Synchronization (gPTP) for RADAR ECUs to prevent timing-based vulnerabilities.
- Implemented: Secure Boot, Key Management, and OTA Update Support; Secure Inter-Core Communication and Memory Protection Unit (MPU).
- Resolved integration challenges and ensured compatibility with internal stacks.
Security Enhancement
- Ensured confidentiality and integrity of ECU firmware and communication protocols.
- Maintained secure handling of cryptographic keys and sensitive data across bootloaders and runtime environments.
