Customer Profile and Requirement: The client was looking for vehicular cybersecurity implementation for ADAS (advanced driver assistance systems) ECU (electronic control units) production to protect the vehicle’s data stored in the network. ADAS ECU is the vehicle’s brain for automotive sensor fusion. Vulnerabilities may exist anywhere in the vehicle; in a vehicle’s communication function or cellphone or tablet connected to the vehicle via Bluetooth, making it easy for the hackers to gain access to the vehicle’s data. For the client, it was their first implementation of a hardware security module, and they partnered with LTTS (L&T Technology Services) to develop cybersecurity design, implementation, and validation for all variants of collision avoidance decision modules for a production program.
LTTS’ Solution: LTTS’ focus was on total security. At the outset, a security requirement analysis was done to refine abstract security specifications. The other solution highlights include:
- Security feature optimization to achieve functional requirements
- Security concept definition and security architecture design
- Security feature implementation
- Security feature verification and validation
Tangible Business Benefits: The outcome was a cybersecure vehicle that adhered to regulatory standards. Custom features were developed to meet OEM security feature requirements. LTTS delivered secure ADAS ECUs in compliance with SAE standards, leveraging the HSM-based hardware; and Threat Analysis and Risk Assessment (TARA) security concept definition, security feature validation, and source code review in compliance with SAE J3061.
