A Trivium-Inspired Pseudorandom Number Generator With A Statistical Comparison To The Randomness Of Securerandom And Trivium, Latoya Niesha Jackson
A Trivium-Inspired Pseudorandom Number Generator With A Statistical Comparison To The Randomness Of Securerandom And Trivium, Latoya Niesha Jackson
Theses and Dissertations
A pseudorandom number generator (PRNG) is an algorithm that produces a sequence of numbers which emulates the characteristics of a random sequence. In comparison to its genuine counterpart, PRNGs are considered more suitable for computing devices in that they do not consume a lot of resources (in terms of memory) and their portability; they can also be used on a wide range of devices. Cryptographically Secure PRNGs (CSPRNGs) are the only type of PRNGs suitable for cryptographic applications. They are specially designed to withstand security attacks. In this thesis, we provide descriptions of two CSPRNGs: Trivium, a hardware-based stream cipher …

Evaluating A Personal Stress Monitoring System, Sneha Gogineni
Theses and Dissertations
Now-a-days, Life is generally much more stressful than in the past. "Stress" is the word that we use when we feel that we are overloaded mentally in our thoughts and wonder whether we can really cope with those placed upon us. Sometimes, stress gets us going and they are good for us but at other times, it could be the cause to undermine both our mental and physical health. The way we respond to a challenge can be considered as a kind of stress. Part of our response to a challenge is physiological and affects our own physical state. When …

A Comparative Study Of Cognitive Systems For Learning, Praneetha Mandava
Theses and Dissertations
Learning is the modification of a behavioral tendency by experience. Memory and reasoning are the most important aspects for learning in humans; information is temporarily stored in the short-term memory and processed, compared with existing memories and stored in long-term memory, and can be re-used when needed. One way to describe an organized pattern of thought or behavior and the categories of information along with their relationships is by using schemas. A cognitive script is one form of a schema that evolves over multiple exposures to the same set of stimuli and/or repeated enactment of a particular behavior. This research …
Design, Cloning, And Expression Of Rat Preptin And Alanine Analogs, Jahbo M. Love
Design, Cloning, And Expression Of Rat Preptin And Alanine Analogs, Jahbo M. Love
Theses and Dissertations
Alanine scanning mutagenesis was employed to determine the structural epitopes of preptin; a newly discovered polypeptide found on the proinsulin-like growth factor II. The alanine scanning mutagenesis was accomplished by the use of, cloning, affinity chromatography, gel electrophoresis, gene sequencing, and mass spectra. However, due to inconclusive results, more research is required before the epitopes can be elucidated.
Using Self-Organizing Maps For Computer Network Intrusion Detection, Manuel R. Parrachavez
Using Self-Organizing Maps For Computer Network Intrusion Detection, Manuel R. Parrachavez
Theses and Dissertations
Anomaly detection in user access patterns using artificial neural networks is a novel way of combating the ever-present concern of computer network intrusion detection for many entities around the world. Anomaly detection is a technique in network security in which a profile is built around a user's normal daily actions. The data collected for these profiles can be as following: file access attempts; failed login attempts; file creations; file access failures; and countless others. This data is collected and used as training data for a neural network. There are many types of neural networks, such as multi-layer feed-forward network; recurrent …
