Hardware-Entangled Software Execution Using Dynamic Pufs, Wenjie Xiong
Hardware-Entangled Software Execution Using Dynamic Pufs, Wenjie Xiong
Yale Day of Data
Low-end computing devices are becoming increasingly ubiquitous, especially due to the widespread deployment of Internet-of-Things products. There is, however, much concern about sensitive data being processed on these low-end devices which have limited protection mechanisms in place. This paper proposes a Hardware-Entangled Software Protection (HESP) scheme that leverages hardware features to protect software code from malicious modification before or during run-time. It also enables implicit hardware authentication. Thus, the software will execute correctly only on an authorized device and if the timing of the software, e.g., control flow, was not changed through malicious modifications. The proposed ideas are based on …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Measurement of soil moisture, especially the root zone soil moisture, is important in agriculture, meteorology, and hydrology. Root zone soil moisture is concerned with the first meter down the soil. Active and passive remote sensing methods used today utilizing L-band(1-2GHz) are physically limited to a sensing depth of about 5 cm or less. To remotely sense the soil moisture in the deeper parts of the soil, the frequency should be lowered. Lower frequencies cannot be used in active spaceborne instruments because of their need for larger antennas, radio frequency interference (RFI), and frequency spectrum allocations. Ground-based passive remote sensing using …

The Research and Scholarship Symposium (2013-2019)
Motivated by high energy costs, people and organizations want to cut back on their energy consumption. However, the only feedback consumers typically receive is a monthly bill listing their total electricity usage (in kWh). Some companies have begun developing systems that allow households and organizations to monitor their energy usage for individual circuits. Available systems are expensive so a CU engineering senior design team has designed, fabricated, and tested a system for use at Cedarville University. The AC power monitoring system has the ability to measure energy consumption for each individual circuit in the breaker panel, store the data, and …

Application Of Ict - I: A Framework For Finding Minimal Test Vectors For Stuck-At-Faults, Azam Beg, S.K. Hasnain
International Conference on Information and Communication Technologies
This paper presents a framework that utilizes Boolean difference theory to find test vectors for stuck-at-fault detection. The framework reads in structural-style Verilog models, and automatically injects single stuck-at-faults (either stuck-at-zero or stuck-at-one) into the models. The simulations are then performed to find minimal sets of test vectors. Using this setup, we conducted experiments on more than 4000 different circuits. The results show that an appreciable savings in test time and effort can be achieved using the method. The same setup can also be used for didactic purposes, specifically for digital design and test courses.
