Improved Worm Simulator And Simulations, Arnold Suvatne

Master's Projects

According to the latest Microsoft Security Intelligence Report (SIR), worms were the second most prevalent information security threat detected in the first half of 2010 – the top threat being Trojans. Given the prevalence and damaging effects of worms, research and development of worm counter strategies are garnering an increased level of attention. However, it is extremely risky to test and observe worm spread behavior on a public network. What is needed is a packet level worm simulator that would allow researchers to develop and test counter strategies against rapidly spreading worms in a controlled and isolated environment. Jyotsna Krishnaswamy, …

Extending Owl With Finite Automata Constraints, Jignesh Borisa

Master's Projects

The Web Ontology Language (OWL) is a markup language for sharing and publishing data using ontologies on the Internet. It belongs to a family of knowledge representation languages for writing ontologies. Answer Set Programming (ASP) is a declarative programming approach to knowledge representation. It is oriented towards difficult search problems. In this project, we developed an extension to OWL add support for collection class constraints. These constraints come in the form of membership checks for sets where these set are computed by finite automata. We developed an inference engine for the resulting language. This engine extends the Java-based Pellet library …

One Social, Sowmya Sampath

Master's Projects

Facebook streams and Twitter tweets represent user content in two common social media systems. Users often have accounts on both these systems and to keep their content current for both of them they must update each separately. It is thus difficult to manage and maintain both of these social networks together. The goal of this project is to build a social website called One Social, where users can view their Facebook streams and Twitter tweets in one single view and thereby easily organize and maintain their updates. In One Social, users can enter a status message and can share it …

Master's Projects

Many times, we can see that if we enter a misspelled search term in any of the search engines like Google, it will provide some help with "Did you mean:...." In my project, I am providing some suggestions for the wrong Japanese text entered by a user.

The Japanese language has three types of writing styles - hiragana, katakana and the most difficult, kanji. A single kanji symbol may be used to write one or more different compound words. From the point of view of the reader, kanji symbols are said to have one or more different "readings." Hence, sometimes …

Automatic Execution Path Finding Tool, Fan Yang

Master's Projects

Today, there are many hackers trying to break software using reverse engineering tech- niques. To better protect software, we need to understand reverse engineering methods. This project presents a tool that automatically analyzes executable code in a manner simi- lar to the way an attack might analyze code.

Using reverse engineering techniques, executables can be disassembled to yield an as- sembly code representation of the program. Assembly code is much more human reada- ble than binary code. With assembly code, an attacker can attempt to modify the program to do something other than what was intended by the developer.

An Online Versions Of Hyperlinked-Induced Topics Search (Hits) Algorithm, Amith Kollam Chandranna

Master's Projects

Generally, search engines perform the ranking of web pages in an offline mode, which is after the web pages have been retrieved and stored in the database. The existing HITS algorithm (Kleinberg, 1996) operates in an offline mode to perform page rank calculation. In this project, we have implemented an online mode of page ranking for this algorithm. This will improve the overall performance of the Search Engine. This report describes the approach used to implement and test this algorithm. Comparison results performed against other existing search engines are also presented in this report. This is helpful in describing the …

Approximate Disassembly Using Dynamic Programming, Abhishek Shah

Master's Projects

Most commercial anti-virus software uses signature based techniques to detect whether a file is infected by a virus or not. However, signature based detection systems are unable to detect metamorphic viruses, since such viruses change their internal structure from generation to generation. Previous work has shown that hidden Markov models (HMMs) can be used to detect metamorphic viruses. In this technique, the code is disassembled and the resulting opcode sequences are used for training and detection. Due to the disassembly step, this process is not efficient enough to use when a decision has to be made in real time.

Analysis Of False Cache Line Sharing Effects On Multicore Cpus, Suntorn Sae-Eung

Master's Projects

False sharing (FS) is a well-known problem occurring in multiprocessor systems. It results in performance degradation on multi-threaded programs running on multiprocessor environments.

With the evolution of processor architecture over time, the multicore processor is a recent direction used by hardware designers to increase performance while avoiding heat and power walls. To fully exploit the processing power from these multicore hardware architectures, the software programmer needs to build applications using parallel programming concepts, which are based upon multi-threaded programming principles.

Since the architecture of a multicore processor is very similar to a multiprocessor system, the presence of the false sharing …

Computational Mirna Target Prediction In Animals, Leyan Tang

Master's Projects

miRNAs are a class of small RNA molecules about 22 nucleotides long that regulate gene expression at the post-transcriptional level. The discovery of the second miRNA 10 years ago was as much a surprise in its own way as the very structure of DNA discovered a half century earlier[1]. How could these small molecules regulate so many genes? During the past decade the complex cascade of regulation has been investigated and reported in detail[2]. The regions of the genome called untranslated regions, or UTRs, proved true to their name: they were indeed untranslated, but certainly not unimportant: they act as …

A Study On Masquerade Detection, Lin Huang

Master's Projects

In modern computer systems, usernames and passwords have been by far the most common forms of authentication. A security system relying only on password protection is defenseless when the passwords of legitimate users are compromised. A masquerader can impersonate a legitimate user by using a compromised password.

An intrusion detection system (IDS) can provide an additional level of protection for a security system by inspecting user behavior. In terms of detection techniques, there are two types of IDSs: signature-based detection and anomaly-based detection. An anomaly-based intrusion detection technique consists of two steps: 1) creating a normal behavior model for legitimate …

This paper investigates the problem of malware detection, specifically metamorphic malwares. The paper …

Geometrical Structure And Analysis Of Association Rules, Sar Rajat

Master's Projects

Association rule mining helps us to identify the association between items from a large transactional data set. It has always been a time consuming process because of repeatedly scanning of the data set. Apriori Algorithm [1] and FP-Tree Algorithm [2] are the two methods to find out the association of items in a large transactional item set. Both the above algorithm works differently (Apriori follows Bottom-Up Approach & FP-Tree follows Top-Down Approach) in order to get the association. Associations of items generated from the above two algorithms can be represented in geometry. The geometrical form of associations is called Simplical …

Approximate Disassembly, Dhivyakrishnan Radhakrishnan

Master's Projects

For the past two decades, computer viruses have been a constant security threat. A computer virus is a type of malware that may damage computer systems by destroying data, crashing the system, or through other malicious activity. Among the different types of viruses, metamorphic viruses are one of the most difficult to detect since such viruses change their internal structures with each mutation, making signature-based detection infeasible. Many construction kits are available that can be used to easily generate metamorphic strains of any given virus. Previous work has shown that metamorphic viruses are detectable using Hidden Markov Models (HMM). In …

Auto-Generation Of Use Case Controllers, Pushkar Marathe

Master's Projects

The thesis is based on the concept of generating machine executable code from UML diagrams. There has been some research done on the same topic but it is mainly focused on class diagrams. My main focus will be on the use case diagrams, and sequence diagrams. Sequence diagrams give us the details of any process in a step-by-step fashion which makes it easier to extract the required information regarding the use cases and the controllers which help us generate the code. The process follows three steps, first being generation of UML diagrams. Secondly, these are converted into XMI (XML Metadata …

Email Data Mining: An Approach To Construct An Organization Position-Wise Structure While Performing Email Analysis, Bhargav Vadher

Master's Projects

In this age of social networking, it is necessary to define the relationships among the members of a social network. Various techniques are already available to define user- to-user relationships across the network. Over time, many algorithms and machine learning techniques were applied to find relationships over social networks, yet very few techniques and information are available to define a relation directly over raw email data. Few educational societies have developed a way to mine the email log files and have found the inter-relation between the users by means of clusters. Again, there is no solid technique available that can …

Improved Software Activation Using Multithreading, Jian Rui Zhang

Master's Projects

Software activation is an anti-piracy technology designed to verify that software products have been legitimately licensed [1]. It is supposed to be quick and simple while simultaneously protecting customer privacy. The most common form of software activation is through the entering of legitimate product serial numbers by users, which sometimes are also known as product keys. This technique is employed by various software, from small shareware programs to large commercial programs such as Microsoft Office. However, software activation based on a serial number appears to be weak, as various cracks for a majority of programs are available and can be …
