嵌入式系统中的内生存储器PUF研究综述OACSTPCD

Physical Unclonable Functions(PUFs)can be regarded as a"chip fingerprint"with lightweight,unpredictable,and difficult to clone characteristics,and have become an important component of IoT hardware security mechanisms.However,the implementation of traditional PUFs requires the addition of FPGA or dedicated integrated circuits at the hardware level,which will increase hardware costs.For billions of existing IoT embedded devices,it is difficult to increase PUF security attributes through hardware modifications.Therefore,we discuss the promising method to implement these intrinsic PUFs on commercial off-the-shelf devices and explore the po-tential applications of intrinsic PUFs.We will provide a systematic review of existing IPUFs,particularly Memroy based Intrinsic PUFs(MIPUFs),and discuss the feasibility and future development directions of IPUFs in existing systems,in order to promote the engineer-ing application of this technology.
