RNG is a prerequisite for secure pprzlink.
Updated libopencm3 already has drivers for RNG.
ChibiOS would have to be updated too, but the new ChibiOS currently doesn't work with TLS module
LPC21 autopilots don't have the RNG hardware.
Tested on Lisa MX. Most stm32 chips have RNG hardware.
@gautierhattenberger any chance you would want to update TLS to work with the new Chibios?
