Impact on secure boot when advance HSE LifeCycle from CUST_DEL to IN_FIELD

[HaiHoangSoftware]

Hi,

Our project configure SMR for secure boot feature in CUST_DEL using plain-text AES key slot owner by HSE_KEY_OWNER_CUST.

The SMR is configured in CUST_DEL and secure boot feature works normal in CUST_DEL.

Is there any impacts on secure boot feature after the HSE lifeCycle advanced to IN_FIELD?

Hi @HaiHoangSoftware 

Generally, restrictions given by life cycle target rather key management than key usage. So, there won't be difference in this case if you advance the life cycle to IN_FIELD.
