Hello.

I am asking in this newsgroup, because I believe FIPS mode can affect the 
answer.

Let assume

  -- Token A is software token, and able to make ECC signatures.

  -- Token B is hardware token providing TRUE random numbers.

Certainly, I'd like the token B be used as random number source as much as 
possible.

Would it be correct if application takes random number from token B, and passes 
to token A to be used as ECC signature nonce ?

Is it compatible with FIPS mode requirements ?

Let's forget for a while that PKCS#11 doesn't provide a way to application to 
pass an own random to ECC signature mechanism.
