Therefore, is it not default enabled. Just curious, will there be concurrent access? If yes, how do you manage the entropy in that case? If you allow access to RNG from normal world, can attacker change the setting to generate more predicatable numbers leading this to secure world as well. I understand that you're leaving the enablement part to customer but you still have to allow RNG access to normal world for that. -Kamlesh
