Abstract:

The Physical Unclonable Function(PUF) is a physical unclonable process function which refers to inputing a challenge to a physical entity,which uses its inevitable changes in the physical details to output a random unpredictable response.To solve the issue of the limited computing, storage and communication capabilities of sensor nodes, according to the analysis of the PUF, a physical unclonable function system(PUFS) framework is defined, and based on this framework, a new Key Exchange protocol is proposed. Finally, a security analysis of our PKE protocol in the universally composable (UC) framework is given in detail. Compared to the traditional public key encryption KE scheme, the PKE protocol does not use any computational assumptions but rather the secure property of the PUFS, and thus our scheme needs less computation and communication cost.

Key words: authenticated key exchange, physical unclonable function, physical unclonable function system, universally composable framework
