FIDO Protocol Based on Physical Unclonable Functions and Its Application into Electronic Contract

In this paper, the emerging Physical Unclonable Function (PUF) and Fast Identity Online (FIDO), are studied for the secure identification (ID) authentication of electronic contract. To solve the unstable response of PUF, error correction algorithms are applied. This paper proposes a high security authentication protocol, which is a FIDO protocol based on PUF. A comparison of the proposed protocol with three classical protocols is presented. The results shows that the proposed protocol has the advantages of anti-cloning and error-correcting compared with existing authentication protocols. Finally, the application of the FIDO protocol based on PUF into the electronic contract is also demonstrated.
