Response-Based Cryptography with Physical Unclonable Functions (PUFs)

Descriptions

The technology, Response-Based Cryptography (RBC), is a protocol that extracts cryptographic keys directly from the uncorrected responses of the physically unclonable functions (PUFs). The purpose of the RBC engine, driven by the server, is to generate matching responses to the ones generated by the PUFs and extract the exact same cryptographic key. The secure server driving the network manages the differences between the PUF responses and the original PUF challenges. In turn, the client devices do not need error correction schemes that match the challenges stored by the server. As a result of the protocol, both the server and the client devices independently generate the same uncorrected PUF responses.
