Exploiting device physics of flash memories for enhancing security and reliability of storage system
Wednesday, March 22, 2023;
3:35 - 4:25 PM
062 Willard Building
Speaker: Biswajit Ray from University of Alabama
Abstract: To address the challenges of exponential data growth, future storage solutions need to provide even higher bit densities, superior performance, greater energy-efficiency, and improved resilience, while guaranteeing security and privacy of end users. These challenges can only be addressed through innovative system design concepts that aptly utilize the physical properties of storage media. While the traditional storage system mainly relies on technology-agnostic algorithmic functions for the ease of portability, such design underutilizes the rich physical properties of the storage media. Thus, state-of-the art storage solutions are inadequate to ensure resilience, energy efficiency, system security and end-user privacy at the edge nodes and extreme environments.

In this talk, I will present a few innovative techniques that will bridge the gap between device and system design approaches to open-up new opportunities for enhancing resilience, security, and privacy of future edge computing/storage applications. I will illustrate how device physics can be used at system-level to derive hardware security primitives for securing NAND flash supply-chain. I will demonstrate our recent attack on recovering deleted information from flash storage using data remanence of memory bits. Finally, I will share my experimental research findings on the radiation effects on the 3D NAND storage and how flash memory can be used for radiation sensing application.
