HSE - Symmetric Encryption not possible

jthelemann — Wed, 22 May 2024 06:16:36 GMT

Hello everybody,

currently I am working with the HSE-B on a S32K344. I want to use the "HSE_SRV_ID_SYM_CIPHER" service in order to perform an AES-CTR encryption/decryption of data in flash memory. When calling the corresponding HSE Service, I always get the error code "HSE_SRV_RSP_NOT_ALLOWED". I already read the HSE Firmware Reference Manual in order to identify the problem, but I cannot figure it out.

I attached picture of following things:

Definition of the NVM key attributes (inclusive symmetric key)
Definition of the corresponding HSE Service
Function call of the corresponding HSE Service

Hope you can help to get rid of this problem.

Thanks!
