Or, How Alice Outwits Eve

Sam Lomonaco, CSEE, UMBC
12:00–1:00pm, Friday, 17 November 2017, ITE 231, UMBC

Alice and Bob wish to communicate without the archvillainess Eve eavesdropping on their conversation. Alice decides to take two college courses, one in cryptography, the other in quantum mechanics. During the courses, she discovers she can use what she has learned to devise a cryptographic communication system that automatically detects whether or not Eve is up to her villainous eavesdropping. Some of the topics discussed are Heisenberg’s Uncertainty Principle, the Vernam cipher, the BB84 and B92 cryptographic protocols. The talk ends with a discussion of some of Eve’s possible eavesdropping strategies, i.e., opaque eavesdropping, translucent eavesdropping, and translucent eavesdropping with entanglement.

Understanding What We Read and Share:
Event Processing from Text and Images

Dr. Frank Ferraro, Assistant Professor, CSEE
1:00-2:00pm Friday, 10 November 2017, ITE 325, UMBC

A goal of natural language processing (NLP) is to design machines with human-like communication and language understanding skills. NLP systems able to represent knowledge and synthesize domain-appropriate responses have the potential to improve many tasks and human-facing applications, like virtual assistants such as Google Now or question answering systems like IBM’s Watson.

In this talk, I will present some of my work—past, on-going, and future—in developing knowledge-aware NLP models. I will discuss how to better (1) encode linguistic- and cognitive science-backed meanings within learned word representations, (2) learn high-level representations for document and discourse understanding, and (3) how to generate compelling, human-like stories from sequences of images.

Frank Ferraro is an assistant professor in the CSEE department at UMBC. His research focuses on natural language processing, computational event semantics, and unlabeled, structured probabilistic modeling over very large corpora. He has published basic and applied research on a number of cross-disciplinary projects, and has papers in areas such as multimodal processing and information extraction, latent-variable syntactic methods and applications, and the induction and evaluation of frames and scripts.

Winning NCCDC, and its practicality in the real world

Bryan Vanek, CSEE, UMBC

12:00noon–1pm Friday, 3 November 2017, ITE 231

The National Collegiate Cyber Defense Competition (NCCDC) takes place every year and gives students an environment where they can develop understanding and operational competency in managing and protecting corporate network infrastructure and business information systems. Competitors participate as the blue team, and try to protect their machines from being infiltrated by the red team, while simultaneously keeping critical services up and running in order for a mock business to stay up and running. After an immense amount of preparation and strife, the UMBC Cyber Defense Team took home its first national title for the competition this year. But what exactly did the team do to prepare for this competition? What exactly happened at the different stages of the competition? And just how practical are these situations in the real world? One of the winning team members will be covering these questions in this week’s CDL, so we hope to see you there!

Bryan Vanek is a UMBC undergraduate computer science major and mathematics minor. In addition to being one of the winning team members for NCCDC, he is currently serving as the president for the UMBC Cyber Defense Team, and is a CWIT T-SITE scholar. He currently works at Interclypse Inc. as a security engineer and software developer, and has had multiple internships and jobs dealing with aspects of computer development and security. Most recently he has completed his second internship at the Department of Defense  in the Summer Internship Program for Information Assurance. Upon graduation he will be returning to the DoD as a member of the Computer Network Operations development Program.

talk: DOE Energy Exascale Earth System Model, 2:30 Tue 10/31, ITE325

 

CHMPR Distinguished Lecture Series

Energy Exascale Earth System Model

Dr. Mark Taylor, E3SM Chief Computational Scientist, Sandia National Laboratories

2:30pm Tuesday, 31 October 2017, ITE 325, UMBC

 

Dr. Taylor will present an overview of the DOE Energy Exascale Earth System Model (E3SM), including Sandia’s role in numerical algorithms, parallel scalability, and computational performance. E3SM is designed to run on upcoming next-generation DOE supercomputers. Adapting simulation codes to these new architectures is expected to be more disruptive than the previous transition from vector to massively parallel supercomputers. E3SM development is driven by several grand challenge science questions focused Earth’s cryosphere, biogeochemical and water cycle systems. E3SM has a new land and atmosphere component models branched from the CESM v1.2, coupled to new MPAS ocean, sea ice, and land ice models.

The current performance and throughput challenges of the E3SM high-resolution coupled configuration on several DOE computers will be discussed. Our current focus is on the NERSC Cori system with Intel Xeon Phi architecture, in the longer term we hope to make effective use of the upcoming NVIDIA GPU based system at ORNL. An analysis is presented of the E3SM spectral element atmosphere dycore following the NGGPS dycore computational evaluation protocol, but with an emphasis on the throughput rates needed for climate simulations. For even higher resolution simulations, we will rely on E3SM’s ability to use unstructured grids in all component models. This will allow us to achieve cloud-resolving resolution in select regions of interest seamlessly within the global modeling system.

Mark Taylor is a mathematician who specializes in numerical methods for parallel computing and geophysical flows. He currently serves as Chief Computational Scientist for the DOE’s Accelerated Climate Modeling for Energy (ACME) project. Mark developed the mimetic/conservative formulation of the spectral element method, one of the atmospheric dynamical cores used in the Community Earth System Model (CESM) and the ACME project. Mark received his Ph.D. from New York University’s Courant Institute of Mathematical Sciences in 1992 and has worked at Sandia National Laboratories since 2004. In 2014 he was awarded The Secretary of Energy Achievement Award for his work unifying the DOE climate modeling research community and enabling the development of high-resolution fully-coupled climate-system simulations.

Science is changing rapidly and new transdisciplinary approaches are resulting in advances across scientific domains. Due to developments in computing and engineering, nested with a changing policy environment, medicine and public health are also at the cusp of a transformation that will accelerate discovery, improve health outcomes, decrease costs, and address the complexity of challenging health problems. To realize these advances requires partnerships between the scientific and health domains. Research communities are developing breakthrough ideas in a variety of diverse areas relevant to health, such as sensor networks, informatics, machine learning and datamining, decision support systems, modeling of behavioral and cognitive processes, as well as system and process harmonization. Solutions that effectively influence health must satisfy a multitude of constraints creating challenges and opportunities that individual disciplines cannot address alone. Computer science and engineering are poised to contribute to these changes by bring sophisticated techniques to partnerships in the biomedical realm. This talk will cover some advances being made and a vision for future.

BFT—From the “Saddest Moment” to the Era of Blockchains

Haibin Zhang, CSEE, UMBC

12:00–1:00pm, Friday, 20 October 2017, ITE 231

Blockchains can generally be divided into two categories: permissionless blockchains (e.g., Bitcoin, Ethereum), and permissioned blockchains (e.g., Hyperledger Fabric). In permissionless blockchains, anyone can participate in the protocol. In permissioned blockchains, participants know the IDs of all other participants but do not need to trust them, a particularly useful scenario for business applications. As an emerging technology transforming business models, permissioned blockchains inspired a large number of industrial implementations. The Hyperledger Project (under the Linux Foundation) became a global collaborative project, now with 150+ industry members. Byzantine fault-tolerant (BFT) protocols regained prominence because they can support permissioned blockchain systems. For building permissioned blockchains, BFT is widely regarded as the most appropriate primitive, one accepted by academe and industry. In this talk, I will describe a number of efficient BFT blockchain systems that I helped invent, including BChain, ByzID, CBFT, and secure causal BFT. In addition, I will share my vision for blockchains and associated research opportunities.

Haibin Zhang is an assistant professor in the CSEE Department at UMBC. He is interested in cloud computing, cryptography, security, privacy, and distributed systems. He received the best paper candidate award at the 33rd IEEE International Symposium on Reliable Distributed Systems and proved the security of a NIST standard on ciphertext stealing.  Zhang is one of the main inventors of Norton Zone, Symantec’s scalable cloud storage, and BChain, a highly efficient BFT protocol fully implemented within Hyperledger blockchain framework.
