Cosc: Paths With Combined Optimal Stability And Capacity In Opportunistic Networks, Shiraz Qayyum, Peizhao Hu, Mohan Kumar
Presentations and other scholarship
Opportunistic networks are characterized by the dynamic connectivity created when mobile devices encounter each other, as they are within close proximity. During these transient opportunities, devices are typically within one-hop wireless range of their neighbors. Opportunistic networks are an effective way, in terms of bandwidth and battery consumption to distribute large volume content among peers. Many existing proposals consider opportunistic networks as a best-effort content delivery approach, which limits their applications. We exploit characteristics of human mobility to derive an effective data forwarding scheme that achieves Combined Optimal Stability and Capacity (COSC) for opportunistic networks. COSC includes a path selection …

An Insider Threat Activity In A Software Security Course, Daniel E. Krutz, Andrew Meneely, Samuel A. Malachowsky
An Insider Threat Activity In A Software Security Course, Daniel E. Krutz, Andrew Meneely, Samuel A. Malachowsky
Presentations and other scholarship
Software development teams face a critical threat to the security of their systems: insiders. A malicious insider is a person who violates an authorized level of access in a software system. Unfortunately, when creating software, developers do not typically account for insider threat. Students learning software development are unaware of the impacts of malicious actors and are far too often untrained in prevention methods against them. A few of the defensive mechanisms to protect against insider threats include eliminating system access once an employee leaves an organization, enforcing principle of least privilege, code reviews, and constant monitoring for suspicious activity. …

Software engineering is largely a communication-driven, team-oriented discipline. There are numerous hurdles for ensuring proper communication and interaction between all project stakeholders, including physical, technological, and cultural barriers. These obstructions not only affect software engineering in industry, but in academia as well. One possible issue that is often overlooked in software engineering education is how to best educate Deaf and hard-of-hearing (Deaf/HoH) students, and how to fully engage them in the classroom. In this paper, we present our experiences in teaching software engineering to Deaf/HoH students. In the classroom, these students work very closely in activities and on project teams …

Understanding And Improving The Culture Of Hackathons: Think Global Hack Local, Adrienne Decker, Eiselt, Kurt, Voll, Kimberly
Presentations and other scholarship
Hackathons bring developers, artists and designers together around a shared challenge: ideate, plan and create an application in a highly constrained time frame. A way to socialize, solve problems, and strengthen soft and hard skills, hackathons have grown tremendously in popularity in the last half decade. Despite this growth, it has been noted that females do not participate in hackathons with the same frequency as males. Some theorize that the hackathon culture is intimidating, does not appeal to women, or that it acts to amplify pre-existing cultural biases in computing. In this paper we introduce an alternative format for hackathons …

Affine-Power S-Boxes Over Galois Fields With Area-Optimized Logic Implementations, Christopher Wood, Marcin Lukowiak, Stanislaw Radziszowski
Presentations and other scholarship
Cryptographic S-boxes are fundamental in key-iterated sub- stitution permutation network (SPN) designs for block ciphers. As a natural way for realizing Shannon’s confusion and diffusion properties in cryptographic primitives through nonlinear and linear behavior, re- spectively, SPN designs served as the basis for the Advanced Encryption Standard and a variety of other block ciphers. In this work we present a methodology for minimizing the logic resources for n-bit affine-power S- boxes over Galois fields based on measurable security properties and find- ing corresponding area-efficient combinational implementations in hard- ware. Motivated by the potential need for new and larger S-boxes, we …

Authenticated encryption (AE) is a symmetric key cryptographic scheme that aims to provide both confidentiality and data integrity. There are many AE algorithms in existence today. However, they are often far from ideal in terms of efficiency and ease of use. For this reason, there is ongoing effort to develop new AE algorithms that are secure, efficient, and easy to use. The sponge construction is a relatively new cryptographic primitive that has gained popularity since the sponge-based K ECCAK algorithm won the SHA-3 hashing competition. The duplex construction, which is closely related to the sponge, pro- vides promising potential for …

Activity Alternative Selection Considering Stochastic Reliability In Project Planning, Devdatta Deo, Michael E. Kuhl
Presentations and other scholarship
Activity Alternative Selection Considering Stochastic Reliability in Project Planning. Project management often involves the selection of alternatives from various options for completion of one or more activities. In some cases in addition to uncertainty in cost and activity completion time, the reliability of the alternatives must also be considered. This situation often arises when alternatives involve new or unproven technologies or processes. In this research, we present a stochastic simulation-based optimization method to evaluate project networks to select from among alternatives for completing project activities when several options are available with stochastic completion times and reliability in terms of the …

Changes in vegetation cover, building construction, road network and traffic conditions caused by urban expansion affect the human habitat as well as the natural environment in rapidly developing cities. It is crucial to assess these changes and respond accordingly by identifying man-made and natural structures with accurate classification algorithms. With the increase in use of multi-sensor remote sensing systems, researchers are able to obtain a more complete description of the scene of interest. By utilizing multi-sensor data, the accuracy of classification algorithms can be improved. In this paper, we propose a method for combining 3D LiDAR point clouds and high-resolution …

Probabilistic graphical models have strong potential for use in hyperspectral image classification. One important class of probabilisitic graphical models is the Conditional Random Field (CRF), which has distinct advantages over traditional Markov Random Fields (MRF), including: no independence assumption is made over the observation, and local and pairwise potential features can be defined with flexibility. Conventional methods for hyperspectral image classification utilize all spectral bands and assign the corresponding raw intensity values into the feature functions in CRFs. These methods, however, require significant computational efforts and yield an ambiguous summary from the data. To mitigate these problems, we propose a …

Presentations and other scholarship
or two consecutive semesters we implemented a “flipped classroom” design in a developmental mathematics classroom. Our interest in implementing an alternative instructional method was born out of frustration with the fact that the students we have been teaching in this course needed to gain a better un- derstanding of mathematics than what our traditional instruc- tional methods seemed to be offering them. The developmental mathematics course is a beginning algebra course covering topics such as systems of equations, quadratic equations and graphing quadratic functions, co-taught by the two of us. Our approach included two different methods of in- struction: we …
