Hi. 

I have been implemented to erase one key of SHE key type after authenticating in S32K3.

But the error happens like below.

is it impossible to erase one key of SHE key type in S32K3?

is there any condition for this?

#define HSE_SRV_RSP_NOT_ALLOWED ((hseSrvResponse_t)0xAA55A21CUL)

/**< @brief The operation is not allowed because of some restrictions (in attributes, life-cycle dependent operations, key-management, etc.). */

Hi @EddiePark 

No, you can't erase only one SHE key. You can find in HSE Service API reference manual:
