DRAM-based PUF
收藏资源简介：
Securing systems with limited resources is crucial for deployment and should not be compromised for other performance metrics like area and throughput. Physically Unclonable Functions (PUFs) emerge as a cost-effective solution for various security applications, such as preventing IC counterfeiting and enabling lightweight authentication. In the realm of memory-based PUFs, the physical variations of available memory systems, such as DRAM or SRAM, are exploited to derive an intrinsic response based on the accessed data row. This study introduces an innovative design of a DRAM-based PUF that utilizes the variations of adjacent DRAM cells to extract a reliable and secure key. The dataset, which is used for validating the proposed design, is generated through Monte Carlo simulations implemented on the Cadence tool. The simulation environment is configured, featuring 11 DRAM devices, each comprising 5K data rows and an 8-bit width. Each DRAM device is associated with a folder containing voltage data collected for each bit, along with the corresponding evaluated response. Additionally, the device folder contains a concatenated 8-bit response.
