Survey of physical unclonable function

Abstract

Though PUF is a new concept in recent years,since it has application prospect for the security of system authentication and key generation,it has become a hot research topic in the field of hardware security.In order to get the whole picture of physical unclonable function for better application in the future research work,first,based on the the different PUF implementations available,this paper classified the detailed design,and summed up the main problems.Then based on these categories,this paper proposed a non-formal property description.Next,from the point of view of cryptographic applications,this paper summarized the PUF application.Finally,this paper pointed out a few meaningful PUF future research directions.
