With the increasing degree of networked ECUs and vehi- cles, the demands on data security are also increasing. The development of a secure E/E architecture in the vehicle requires, among other things, complex cryptographic calcu- lations in the ECUs. For this purpose, semiconductor manu- facturers integrate Hardware Security Modules (HSM) into their microcontrollers, which accelerate these calculations and represent a Hardware Trust Anchor (HTA). This serves as a trustworthy source of cryptographic calculations To use
