I have MPC5748G. I want to store cryptographic keys in HSM.
1. Can I store 32 bytes key in it?
2. When I enable HSM through DCF client, the bit SSCM_UOPS_HSE does not reflects the same(HSE bit gives enabled/disabled status). What are the possible reasons for this?
Hello,
1. No, because C3 engine only supports 128-bit key size.
2. Incorrect DCF records or DCF record is placed incorrectly in memory.

What about using 2 Read/Write slots simultaneously in KIDX for storing the cryptographic key, can that be done? Would there be loss of information?
No, you cannot use 2 consecutive indexes.
