Crypto and Csec

xyzhang — Wed, 18 Mar 2026 03:54:46 GMT

Hello, I'm sorry to disturb you. Now I have come across a problem and I need your assistance. I am implementing the encryption and decryption functions using the Crypto component in the AUTOSAR architecture. This function is a pure software encryption algorithm. So, how can I achieve hardware-based encryption and decryption? For example, CSEC in the SDK. The chip model is the S32K146 series. Looking forward to your reply.

It's not clear to me - what kind of software do you use? In our older Autosar classic MCAL packages, in newer RTD packages, in SDK – CSEc module is always used for all operations, there’s no SW emulation.

The newest and recommended SW drivers are RTD drivers:

There are both Autosar and non-Autosar layers.

You can also take a look at this application note:

There’s just simple CSEc driver in the SW examples (it’s not part of MCAL, RTD or SDK).
