Title
D-PUF: an intrinsically reconfigurable DRAM PUF for device authentication in embedded systems.
Abstract
Physically Unclonable Functions (PUFs) have proved to be effective and low-cost measure against counterfeiting by providing device authentication and secure key storage services. Memory based PUF implementations are an attractive option due to the ubiquitous nature of memory in electronic devices and the requirement of minimal (or no) additional circuitry. DRAM based PUFs are particularly advantageous due to their large address space and multiple controllable parameters during response generation. However, prior works on DRAM PUFs use a static response generation mechanism making them vulnerable to security attacks. Further, they result in very slow device authentication, are not applicable to off-the-shelf DRAM modules, or require DRAM power cycling prior to authentication. In this paper, we propose D-PUF, an intrinsically reconfigurable DRAM PUF based on refresh pausing. A key feature of the proposed DRAM PUF is that it can be reconfigured by varying the refresh-pause interval, which changes it's challenge-response behavior, making it robust against various attacks. We use the PUF to design a secure, low-overhead methodology for performing device authentication. The design is implemented and validated using an Altera Stratix IV GX FPGA based Terasic TR4-230 development board and several off-the-shelf 1GB DDR3 DRAM modules. Our experimental results demonstrate a 4.3×-6.4× reduction in authentication time, compared to previous work. Using controlled temperature and accelerated aging tests, we also demonstrate the robustness of our authentication mechanism to temperature variations and aging effects.
