Lowering time for key-renewal to 300sec

[damiang]

Hi all,

my question is about configuring the time for key-renewal on a smart console (to 300 sec).

can it have an impact on the system on the long run?

is there any sk or best practise on this?

Thank you.

Yes, considering that key exchange uses asymmetric encryption, which is more computationally expensive than the symmetric encryption used for bulk data encryption.
