I have hardware based RNG which consists of TRNG and PRNG. TRNG is giving out 512 bit number which is being used as seed for PRNG. RNG is generating 160 bit random number using PRNG and reseeding is done after 2^20 numbers. I want to use hardware based RNG as entropy source. What should be used as source of entropy i.e. output of TRNG or PRNG ?
Any help/reply is appreciated please.
Thanks & Regards,
