In theory the solution to this problem is TCG remote attestation, but 
you can't actually use it (yet). The practical half-solution is to 
obfuscate your protocol as much as you can. It's not clear to me whether 
  a shared secret or PKI provides more obfuscation; certainly PKI is 
more complex and computationally-intensive.
