State-of-the-art automotive embedded security

Secure the vehicle against unauthorized access is fundamental, but not enough. As we see in other industries, hackers extend their strategies along with the enhancing security measures. Within the vehicle, hardware security modules (HSMs) help to build a secure platform that is protected from unauthorized access of key material and software manipulation.

EB zentur is a performance- and resource-optimized solution for hardware security modules to access cryptographic hardware accelerators or provide software implementation for selected algorithms. It can be integrated into various operating systems.


Maximum flexibility regarding hardware options

Abstractions of cryptographic calculations to the upper software layers ensure hardware independence.

Hardware trust anchor

EB’s software in the trusted execution environment provides a secure key storage and monitors the host cores.

Accelerated cryptographic calculations

Parallel execution of hardware-accelerated cryptographic calculations speeds up the entire process.
