COLLOQUIUM Department of Computer Science and Engineering University of South Carolina Rong Su Abstract We are at the dawn of the 4th industrial revolution - the era of the ICT backed Smart Manufacturing (or Industry 4.0). Among all challenges, the problem of how to model and manage efficiently the low volume high mixed (LVHM) manufacturing processes has been gaining more and more attentions from both academia and industry, owing to the rise of the maker/Do-It-Yourself (DIY) culture around the world. The major challenges in both modelling and operation planning are due to the complexity resulted from the scale and heterogeneity of the system, and the sophistication of relevant operations. In this talk I will first briefly mention one novel event-based modelling framework for cyber physical material handling, which, by separating operations and the corresponding materials, can significantly improve reusability of pre-developed models, making it potentially feasible to support a “drag and play” strategy, when constructing or reconfiguring a material handling system without a need of starting from scratch. After that, I will focus on a novel task routing and scheduling approach within a distributed synthesis framework based on time weighted discrete-event models. By going through an example of operation planning for linear cluster tools, I will show the potential advantage of this supervisor synthesis approach. In addition, I will show that the same modelling and synthesis framework can be applied to robot motion planning problems, accompanied by large–scale case studies in a simulated environment. Dr. Rong Su obtained his Bachelor of Engineering degree from University of Science and Technology of China in 1997, and Master of Applied Science and PhD degrees from University of Toronto in 2000 and 2004, respectively.

Towards Practical Program Analysis: Introspection and Adaptation

COLLOQUIUM Department of Computer Science and Engineering University of South Carolina Shiyi Wei Abstract Software is ubiquitous. As its importance grows, the mistakes made by programmers have an increasingly negative effect, leading to critical failures and security exploits. As software complexity and diversity grows, such negative effects become even more likely. Automated program analysis has the potential to help. A program analysis tool approximates possible executions of a program, and thereby can discover otherwise hard-to-find errors. However, significant challenges must still be overcome to make program analysis tools practical for real-world software. I have gained substantial experience in building novel program analysis tools whose aim is to produce more secure and reliable software. Recently, I have focused on the challenge of building analysis tools that perform well (i.e., can analyze realistic code in a reasonable amount of time) and are precise (i.e., do not produce too many "false alarms"). To this end, I have developed an approach that systematically uncovers sources of imprecision and performance bottlenecks in program analysis. The goal is to significantly reduce the time-consuming manual effort otherwise required during analysis design process. In addition, I have designed an adaptive analysis, in which appropriate techniques are selected based on the coding styles of the target programs. Selection is based on heuristics derived from a machine learning algorithm. The idea is that precise techniques can be deployed only as where and when they are needed, leading to a better balance overall. Shiyi Wei is a post-doctoral associate at University of Maryland, College Park. He obtained his Ph.D. in Computer Science from Virginia Tech in 2015, and B.E. in Software Engineering from Shanghai Jiao Tong University in 2009. His research interests span the areas of Programming Languages, Software Engineering and Security. The goal of his research is to make program analysis practical for improving the security and reliability of real-world software. He has published articles at top venues in his areas of interest, such as PLDI, FSE, ECOOP, and ISSTA. He has interned at IBM T. J. Watson Research Center.

Security Analytics for Defeating Automated Internet-scale Threats

Friday, February 17, 2017 - 10:30 am
300 Main B101
Computer Science and Engineering Colloquium Abstract: Billions of devices are connected to the Internet today, significantly changing the threat landscape by lending adversaries unprecedented resources to launch automated attacks, and requiring new threat analysis and defenses. In this talk, I will argue that big data analytics can play an important role in securing the Internet, and exemplify my argument with applications to distributed denial of service (DDoS), malware analysis, and massively multiplayer online role-playing game (MMORPG) bot detection. First, I will present an analytical view of 50,000 unique and verified DDoS attacks on services on the Internet. I will show how adversaries’ spatiotemporal traits follow predictable patterns, consecutive attacks follow certain patterns allowing prediction of future threat, and attackers are highly collaborative. Second, I will show how big data analytics are applied to malware analysis and software behavior profiling, and demonstrate optimizations to scale such analytics. Third, I will discuss an analytics framework for game bot detection in MMORPG using self-similarity of user behavior. By applying this framework to three large online games, I demonstrate how this analytics approach can be used to extract general features of behavior and effectively detect game bots in practice. I will conclude by highlighting my vision of how this analytics approach can be applied to realize effective and proactive defenses, and extended for other applications.

Speaker: Dr. Ron Addie Abstract: It is understood that ICT security can be defined and enforced through rules. In this work, the concept of rules which define and ensure users' access to services is introduced. Examples of how service is hindered by otherwise sensible security rules are presented. The concept of service protection policies is introduced. We use ns3 and Click in simulations to check the consistency of aggregate security policy by checking that service protection rules are valid. We show that these can improve the performance of the network experienced by users and increase network security. Short Bio: Ron Addie received his BSc degree from Monash University in 1972 and completed his PhD at Monash University in the area of semi-Markov queues in 1986. From 1972 to 1992, he worked in Telstra Research Laboratories where he was involved in the development of ATM, teletraffic, and network analysis and design. In 1992 he moved to the University of Southern Queensland, where he holds the position of Associate Professor. His current research interests include queueing theory for long-range dependent traffic, rare event simulation, layered network design, network analysis, design and simulation software and security of web information systems. He is the author or co-author of many journal and conference papers, primarily in the area of communications, with more 1000 citations (according to Google Scholar).

Mobile Application for Shipping Goods for Individuals and Truckers in India

Friday, January 6, 2017 - 09:30 am
Dean’s Conference room, Swearingen.
THESIS DEFENSE Department of Computer Science and Engineering University of South Carolina Author : Sendurr Selvaraj Advisor : Dr. Jianjun Hu Date : Jan 6th 2017 Time : 09:30 am – 10:30 am Place : Dean’s Conference room, Swearingen. Abstract India is a vast country with majority of its cities and towns connected through roads. Road transportation contributes to 86% share of the freight transport of the country with trucking companies dominating the entire space. With growing economy and demands raising, the quality of service of the trucking company remains poor. The major reasons are unorganized practice and lack of transparency. Moreover, limited access for customers to reach out to truckers to transport their goods. This thesis aims to create a platform for customers and truckers to realize their needs with a help of a mobile application. Customers can search for truckers nearest to their location based on their needs. In addition, customers can also post their transport requirements which can be viewed by truckers. Truckers have options to update their travel plan well in advance making sure they run on full capacity. The application captures customers’ ratings for truckers thus building truckers’ creditability and in-turn improving quality of service. The platform provides a transparent mode of communication between customers and truckers on finalizing prices and eliminating middlemen, who in reality would draw commissions. The scope of the application can be extended to advertisement feeds, deals and truck sales as a revenue generation model to bare its operational cost.

Positioning commuters and Shoppers Through Sensing and Correlation

Thursday, November 10, 2016 - 04:15 pm
Swearingen 3A75
DISSERTATION DEFENSE Department of Computer Science and Engineering University of South Carolina Author : Rufeng Meng Advisor : Dr. Srihari Nelakuditi Abstract Positioning is a basic and important need in many scenarios of human daily activities. With position information, multifarious services could be vitalized to benefit all kinds of users, from individuals to organizations. This dissertation proposes solutions to address the need of positioning in people’s daily life from two aspects: transportation and shopping. All the solutions are smart-device-based (e.g. smartphone, smartwatch), which could potentially benefit most users considering the prevalence of smart devices. In positioning relevant activities, the components and their movement information could be sensed by different entities from diverse perspectives. The mechanisms presented in this dissertation treat the information collected from one perspective as reference and match it against the data collected from other perspectives to acquire absolute or relative position, in spatial as well as temporal dimension. To help drivers improve safety and ease the tension from driving, two correlated systems, Omni View and Driver talk, are provided. These systems infer the relative positions of the vehicles moving together by matching the appearance images of the vehicles seen by each other, which help drivers maintain safe distance from surrounding vehicles and also give them opportunities to precisely convey driving related messages to targeted peer drivers. To improve bus-riding experience for passengers of public transit systems, RideSense is developed. This system correlates the sensor traces collected by both passengers’ smart devices and reference devices in buses to position passengers’ bus-riding, spatially and temporally. With this system, passengers could be billed without any explicit interaction with conventional ticketing facilities in bus system, which makes the transportation system more efficient. For shopping activities, AutoLabel comes into play, which could position customers with regard to stores. AutoLabel constructs a mapping between WiFi vectors and semantic names of stores through correlating the text decorated inside stores with those on stores’ websites. Later, through WiFi scanning and a lookup in the mapping, customers’ smart devices could automatically recognize the semantic names of the stores they are in or nearby. Therefore, AutoLabel-enabled smart device serves as a bridge of information flow between business owners and customers, which could benefit both sides.
