Physically Unclonable Functions (PUF) can generate random numbers based on semiconductor differences (silicon fingerprints) in integrated circuits (IC). In this paper, we propose 1-out-of-n Oblivious Transfer and Anonymous Password-Based Authenticated Key Exchange (APAKE) using PUF. By using our protocols, it is possible to get secret information without using direct input of secret key. At the same time, mutual authentication can also be achieved in our proposed method. Our proposed protocols also have the advantage of enhancing security by physically exchange of PUF such as IC card and its reader.
