Security solutions in software are often not sufficient to achieve the desired level of ECU security. Hardware security modules (HSM) increase the resistance of embedded systems to more complex attacks and offer greater protection for key material and against software manipulation.
However, the process of integrating hardware security modules is highly complex and requires the creation of a second, independent software environment in the control unit. Special requirements relating to security apply here that are not congruent with the generally known demands of functional safety on software development.
Resorting to specific security expertise ensures that using an HSM does not negate the attainable gain in security. Using a turnkey software solution with well-defined interfaces makes the development complexity manageable by encapsulating the security functions, leaving the application developer free to concentrate on the main objective – ensuring ECU functionality.
ESCRYPT has extensive experience in the implementation and integration of hardware security modules through many industrial and research projects. Our security experts provide advice on choosing and integrating the hardware security modules into existing infrastructure and applications. In doing so, they place particular emphasis on customers’ individual system and process requirements.
