Run-Time Accessible DRAM PUFs in Commodity Devices
Wenjie Xiong,André Schaller,Nikolaos Athanasios Anagnostopoulos,Muhammad Umair Saleem,Sebastian Gabmeyer,Stefan Katzenbeisser,Jakub Szefer +6 more
TL;DR: 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 FPGA implementations for their operation.
Proceedings ArticleDOI
Intrinsic Rowhammer PUFs: Leveraging the Rowhammer effect for improved security
André Schaller,Wenjie Xiong,Nikolaos Athanasios Anagnostopoulos,Muhammad Umair Saleem,Sebastian Gabmeyer,Stefan Katzenbeisser,Jakub Szefer +6 more
TL;DR: This work presents a new type of a memory-based intrinsic PUF, which leverages the Rowhammer effect in DRAM modules to design a novel PUF that makes use of bit flips, which occur inDRAM cells due to rapid and repeated access of DRAM rows.
Journal ArticleDOI
Decay-Based DRAM PUFs in Commodity Devices
André Schaller,Wenjie Xiong,Nikolaos Athanasios Anagnostopoulos,Muhammad Umair Saleem,Sebastian Gabmeyer,Boris Skoric,Stefan Katzenbeisser,Jakub Szefer +7 more
TL;DR: This paper focuses on a new class of run-time accessible, decay-based, intrinsic DRAM PUFs in commercial off-the-shelf systems, which requires no additional hardware or FPGA implementation for their operation.
Book ChapterDOI
Lightweight Anti-counterfeiting Solution for Low-End Commodity Hardware Using Inherent PUFs
TL;DR: A lightweight anti-counterfeiting solution using intrinsic Physically Unclonable Functions PUFs, which are already embedded in most commodity hardware platforms, and a security architecture to protect the platform's firmware by using a modified boot loader is proposed.
Book ChapterDOI
PUF-Based Software Protection for Low-End Embedded Devices
TL;DR: This work presents a novel software protection scheme, which is particularly suited for already deployed low-end embedded devices without secure hardware and combines techniques based on self-checksumming code with Physically Unclonable Functions (PUFs) to establish a hardware-assisted software protection.
