Hi @alexsun
CSEc on S32K146 follows only SHE specification, so this function is not supported by hardware. For software emulation, you can use a library like wolfssl:
https://www.wolfssl.com/
Notice that this packages is included in SDK for S32K1xx. Latest version of SDK is 4.0.3. It can be installed to S32 Design Studio IDE 3.4 using menu Help -> S32DS Extensions and Updates.

Now I can see that it's somehow used only in lwip example on S32K148. That's the only device from S32K1 family which has ethernet module.
So, there's no example for S32K146.
If you have any questions about wolfssl, please follow:
