New piece of information I am trying to understand. So in the M1 message, we receive a nonce, aka the PKE (DH Key from the enrollee). According to this document, the formula for generating these DH Keys is g^AB mod p, aka PKR result^PKE private number mod p. (G is the public number from the registrar, AB is the enrollee's private number used to generate its own public number, and p is the prime modulus. Now, both the enrollee and the registrar each know the shared secret, which I am led to believe is the seed of the PRNG, (I may be wrong here but it all make sense... for now.)
For more information about Diffle-Hellman Keys, (DH Keys), do a quick youtube search for dh key exchange (can't post youtube links).
You can read more about modular arithmetic here.
I'll be looking more into DH Keys and their integration with PRNGs over the next few days/weeks. If you find anything, leave a comment.
