Challenge/response system
A challenge/response system separates a physically unclonable function from the challenge/response. Bits in a challenge are used to qualify random data values. The random data values are permuted to generate a result. The result is used to encrypt a response that is sent in reply to the challenge. Additional permuting mechanisms may be used to further obfuscate the response.
