Run-Time Accessible DRAM PUFs in Commodity Devices [chapter]

Wenjie Xiong, André Schaller, Nikolaos A. Anagnostopoulos, Muhammad Umair Saleem, Sebastian Gabmeyer, Stefan Katzenbeisser, Jakub Szefer
2016 Lecture Notes in Computer Science  
This paper is the first to enable the run-time access of decay-based intrinsic DRAM PUFs in commercial off-the-shelf systems, which requires no additional hardware or FPGAs.  ...  So far, most PUF constructions require addition of new hardware or FPGA implementations for their operation. Recently, intrinsic PUFs, which can be found in commodity devices, have been investigated.  ...  The authors would like to thank Kevin Ryan and Ethan Weinberger for their help with building the heater setup used in the experiments, and Intel for donating the Intel Galileo boards used in this work.  ...

Intrinsic Rowhammer PUFs: Leveraging the Rowhammer effect for improved security

Andre Schaller, Wenjie Xiong, Nikolaos Athanasios Anagnostopoulos, Muhammad Umair Saleem, Sebastian Gabmeyer, Stefan Katzenbeisser, Jakub Szefer
2017 2017 IEEE International Symposium on Hardware Oriented Security and Trust (HOST)  
In this work, we present a new type of a memory-based intrinsic PUF, which leverages the Rowhammer effect in DRAM modules; the Rowhammer PUF.  ...  Our PUF makes use of bit flips, which occur in DRAM cells due to rapid and repeated access of DRAM rows.  ...  The resulting PUF readout time is similar to existing runtime accessible decay-based DRAM PUFs. B.  ...
