Cryptography - Direct Onboard ECU Security

Software for ECUs in the vehicle must be protected from unauthorized access and manipulations. Authentication mechanisms or signature validations provide an effective protection.

EB provides you with embedded-conform cryptography solutions that take account of the special requirements in the automobile and the vehicle infrastructure. These include not only the implementation and integration of your cryptographic application in the ECU environment, but also a dedicated EB Crypto Library that can be easily adapted for the tresos framework. The library is implemented using the HIS standard and contains not only all typical cryptographic routines but also the "Cryptographic Abstraction layer (CAL)" recently accepted as HIS standard. With all common methods, it forms the basis for your cryptographic applications.

For your specific applications, we prepare customer-specific solutions and accompany you during the complete development process: from the requirements analysis and concept phase, including the design, implementation and test, and ending with the integration and documentation.

Employed Algorithms and Standards

• Cryptographic Abstraction Layer (CAL)
• Symmetric (AES) and asymmetric procedure (ECC, RSA)
• Hash functions (MD5, SHA-1, RIPEMD-160)
• Challenge-response authentication and zero-knowledge protocols
• Signature generation and validation
• Key generation
