Hi all,

Does anyone know if using software random generator seeded with TRNG to provide random delays for Fault Injection Hardening library is correct from PSA Level 3 certification point of view?

The basic idea is to :

1. Use TRNG to provide seed for software random generator on fih_delay_init.
2. Use software random generator to implement fih_delay_random.
3. Periodically reseed software random generator with data from TRNG (optional).

Thanks,

Roman.
