So I'm reading up on unconditionally secure authentication in Simmon's
Contemporary Cryptology, and he points out that with RSA, given d,
you could calculate e (remember, this is authentication not
encryption) if you could factor n, which relates the two. However,
the implication is in the less

I came across the same problem a couple of years ago (and indeed
iterated through private/public key solutions with a colleague). The
problem is that you can still give your private key to somebody else.
There's no real deterrent unless that private key is used for many
other purposes,

However, anyone I show this proof to can then masquerade as a silver

way to prevent this is to create a private/public key pair and
instead of the nonce use the hash of
