Automotive Cybersecurity
End-to-end cybersecurity engineering — from TARA and concept development to secure ECU implementation, OTA updates, and penetration testing.
Building security into the architecture from the start — threat analysis, concept development, and goal derivation aligned to ISO 21434.
TARA
- Threat Analysis and Risk Assessment per ISO 21434
- Asset identification and damage scenario analysis
- Attack path analysis and risk determination
- Cybersecurity goals derivation from TARA outputs
Cybersecurity Concept Development
- Cybersecurity concept aligned to system goals
- Secure architecture for communication, diagnostics, SW update, and intrusion detection
- Secure ECU, Gateway, and backend server architecture
From HSM integration to cryptographic services, secure boot, and runtime protection — hardening ECUs against real-world attack vectors.
HSM / HSE Integration

- Key management and provisioning workflows
Cryptographic Services
- Symmetric encryption (AES-128/256)
- Asymmetric encryption (RSA, ECC)
- HASH functions (SHA-256, SHA-384)
- Digital signatures and MAC generation/verification
Secure Boot with RoT
- Root of Trust (RoT) establishment on target silicon
- Bootloader authentication and chain of trust
- Secure flash and anti-rollback mechanisms
- Integration with HSM/HSE for key storage
Secure ECU Communication
- Secure CAN communication (SecOC / MAC)
- TLS for Ethernet-based ECU communication
- Wi-Fi security (WPA3, certificate-based auth)
- Secure ECU access and authentication for diagnostics
Secure Software Updates
- Secure SW updates over CAN / Ethernet
- Secure OTA updates with rollback protection
- Package signing and integrity verification
- UDS-based secure flashing workflows
Secure Runtime & Storage
- Secure runtime execution and memory protection
- Secure storage for keys, certificates, and calibration data
- Secure debug access control
- Secure logging and audit trails
End-to-end security for OTA infrastructure — from SW package creation through campaign management and access control.
Secure SW Package Creation
- Package signing using symmetric & asymmetric cryptography
- Integrity and authenticity verification workflows
- Delta update and compression with security preservation
Secure Campaign Creation
- Secure campaign lifecycle management
- Target vehicle group authorization and rollout control
- Rollback and recovery policy enforcement
Secure Access Control & Monitoring
- Identity and Access Management (IAM) integration
- Role-based access control for backend operations
- Secure monitoring, alerting, and audit logging
Structured security testing that validates the effectiveness of implemented cybersecurity measures — from functional verification to adversarial testing.
Cybersecurity Verification & Validation
- Verification of cybersecurity goals and requirements
- Test case derivation from TARA and concept
- Evidence generation for ISO 21434 compliance
Vulnerability Assessment & Penetration Testing
- Attack surface identification and VAPT execution
- Interface-level probing: CAN, Ethernet, OBD, Wi-Fi
- Finding triage, severity rating, and remediation support
Fuzz Testing & Robustness Testing
- Protocol-level fuzz testing (CAN, UDS, Ethernet)
- Malformed input handling and edge case validation
- Robustness verification under unexpected input conditions
