This config controls the DPA (Differential Power Analysis) protection
|
||
|
|
knob for the crypto peripherals. DPA protection dynamically adjusts
|
||
|
|
clock frequency of the crypto peripheral. DPA protection helps to make it
|
||
|
|
difficult to perform SCA attacks on the crypto peripherals. However,
|
||
|
|
there is also associated performance impact based on the security level
|
||
|
|
set. Please refer to the TRM for more details.
