Towards Side-Channel Infrastructure For Software Implementations Of Pqc Algorithms, Tristen Teague May 2024

Towards Side-Channel Infrastructure For Software Implementations Of Pqc Algorithms, Tristen Teague

Graduate Theses and Dissertations

Post-Quantum Cryptography (PQC) is a new class of asymmetric cryptography algorithms that are supposed to be secure against both classical computers and quantum computers through Shor’s algorithm. Since PQC algorithms are currently being standardized, they will replace older standardized asymmetric algorithms (such as RSA) and will be deployed within the digital infrastructure. Before implementations of the PQC algorithms are placed into the infrastructure, they must undergo evaluation of both performance and security. One such security issue that needs large investigation before deployment are side-channels. Side-channel attacks (SCA) are a method of gathering information from the implementation, such as power-consumption and …

Outcome Measures Or Graduation Rates, That Is The Question, Miran Kang May 2024

Outcome Measures Or Graduation Rates, That Is The Question, Miran Kang

Graduate Theses and Dissertations

The study compared the Outcome Measures (OM) to the traditional Graduation Rates (GR) to ascertain if OM portrayed the performance of higher education institutions differently than GR and to determine which of the two metrics aligned better with accountability policy objectives. GR refers to the percentages of first-time, full-time students who obtain a degree or certificate within 150% of the normal time. OM presents the award status of all degree/certificate-seeking undergraduate students on four cohorts: first-time, full-time (FTFT); first-time, part-time (FTPT); non-first-time, full-time (NFTFT); and non-first-time, part-time (NFTPT).

The Effect Of Crime On Mental Health In South Africa, Magda Tsaneva, Lauren-Kate Laplante May 2024

The Effect Of Crime On Mental Health In South Africa, Magda Tsaneva, Lauren-Kate Laplante

Economics

This paper examines the impact of district-level crime rates in South Africa on individual depression symptoms. We use panel data from the National Income Dynamics Survey collected between 2008 and 2014 and estimate an individual fixed effects regression model, thus controlling for characteristics of the individual's environment that could affect crime and mental health. We find that an increase of one standard deviation in property (violent) crime is associated with a 7.2 (8.7) percentage point increase in the probability of depression symptoms. Analysis of potential mechanisms suggests that indirect exposure to crime likely affects mental health by increasing stress rather …

Analysis Of The Relationship Between Religion, Abortion, And Assisted Reproductive Technology: Insights Into Cross-National Public Opinion, Amy L. Adamczyk, Brittany Suh, Lindsay Lerner

Publications and Research

With advancement in reproductive technologies, public opinion regarding these procedures varies considerably across the world. While prominent public debates have focused on abortion, we know less about the factors shaping feelings regarding Assisted Reproductive Technologies (ART). Both procedures challenge the idea that human life starts with conception – with the fertilization of an embryo. Using European Values Survey data and multilevel modeling, we compare how religion and other personal and country-level factors shape disapproval toward abortion and ART. Conservative Protestants and people who are more engaged with their religion and live in a more religious country are more likely to …
