cMix: Anonymization by High-Performance Scalable Mixing

Cyber Defense Lab, CSEE Dept., UMBC

11:15am-12:30pm Friday, 29 January 2016, ITE 231

cMix is a cryptographic protocol for mix networks that uses pre-computations of a group-homomorphic encryption function to avoid all real-time public-key operations by the senders, mix nodes, and receivers. Like other mix network protocols, cMix can enable an anonymity service that accepts inputs from senders and delivers them to an output buffer, in a way that the outputs are unlinkable to the inputs. cMix’s high-performance scalable architecture, which results from its unique pre-computation approach, makes it suitable for smartphone-to-smartphone use while maintaining full anonymity sets independently per round.

Each sender establishes a shared key separately with each of the mix nodes, which is used as a seed to a cryptographic pseudorandom number generator to generate a sequence of message keys. Each sender encrypts its input to cMix with modular multiplication by message keys. cMix works by replacing the message keys, which are not known in the pre-computation, in real time with a precomputed random value.

Our presentation includes a detailed specification of cMix and simulation-based security arguments. We also give performance analysis, both modeled and measured, of our working prototype currently running in the cloud.

cMix is the core technology underlying our larger PrivaTegrity system that allows smart devices to carry out a variety of applications anonymously (including sending and receiving chat messages), with little extra bandwidth or battery usage. This talk focuses on cMix.

Joint work with David Chaum (Voting Systems Institute), Aniket Kate (Purdue Univ.), Anna Krasnova (Radboud Univ.), Joeri de Ruiter (Univ. of Birmingham), Alan T. Sherman (UMBC).  See and recent articles in Wired and Fortune for discussion.

Favid Javani is a PhD student working with Dr. Sherman. He earned a MS from the Middle Eastern Technical University, Turkey, with a thesis on lattice-based cryptography.

Do you love creating new ways to represent and visualize data? Or are you a data science/ML/AI guru who can’t get enough of Major League Baseball?

A Baseball Analytics Hackathon will be hosted by the Baltimore Orioles and Booz Allen Hamilton from 10:00am to 7:00pm Friday, 5 February 2016 at Oriole Park at Camden Yards Baltimore. It is an opportunity to work with baseball executives and data scientists to refine your data science and analytic skills and show off your creativity by finding new ways to change the game.

Hackathon participants will work to develop innovative data science and visualization solutions using unique datasets that the hosts will provide alongside anything else that is openly available on the Internet. They hope that bringing together creative minds in a competitive environment will lead to novel solutions to some of the questions that the baseball industry is trying to answer. Projects will be judged by Orioles executives and other data scientists. Prizes will be awarded for the most impressive projects.

You may register as either an individual or group participant. Space is limited, so make sure to sign up before the deadline of January 22nd, 2016. Participants will receive notice of their acceptance by Monday, January 25th. Breakfast, lunch, and snacks will be provided.

Multiple Tenure-track Faculty Positions Starting Fall 2016

Computer Science and Electrical Engineering
University of Maryland, Baltimore County

UMBC’s Department of Computer Science and Electrical Engineering invites applications for three tenure-track Assistant Professor positions to begin in Fall 2016. Exceptionally strong candidates for higher ranks may be considered. Applicants must have or be completing a Ph.D. in a relevant discipline, have demonstrated the ability to pursue a research program, and have a strong commitment to undergraduate and graduate teaching. Candidates will be expected to build and lead a team of student researchers, obtain external research support and teach both graduate and undergraduate courses.

All areas of specialization will be considered, but we are especially interested in candidates in the following areas: information assurance and cybersecurity; mobile, wearable and IoT systems; big data with an emphasis on machine learning, analytics, and high-performance computing; knowledge and database systems; hardware systems and experimental methods in circuits, devices, VLSI, FPGA, and sensors; cyber-physical systems; low-power systems; biomedical and healthcare systems; and methods and tools for hardware-software co-design.

The CSEE department is energetic, research-oriented and multi-disciplinary with programs in Computer Science, Computer Engineering, Electrical Engineering and Cybersecurity.

10-11:00am Thursday 28 January 2016, ITE 459, UMBC
postponed

This talk will provide an overview of current programs and activities related to Big Data and Data Science at NSF, and also highlight NSF’s inter-agency engagements in this topic area. The talk will also discuss future directions for Data Science research, education, and infrastructure. Considering that Data Science is a rapidly emerging, evolving field and discipline, ample time will be provided for Q&A and discussions about where the field ought to be going, given what we know today.
Dr. Chaitan Baru is currently a senior advisor for data science in the Computer and Information Science and Engineering Directorate at the National Science Foundation. He is a Distinguished Scientist and Associate Director of Data Initiatives at the San Diego Supercomputer Center (SDSC), UC San Diego where he works on applied and applications-oriented research problems related to data management and data analytics.

Dr. Baru has participated in a number of “data cyberinfrastructure” initiatives, including as Principal Investigator of the OpenTopography project; Cyberinfrastructure Lead, Tropical Ecology, Assessment and Monitoring network; Co-Investigator of the Cyberinfrastructure for Comparative Effectiveness Research project; Member of the founding Senior Management Team of the National Ecologial Observatory Network and Co-PI of the NEON Cyberinfrastructure Testbed; Co-PI of the CUAHSI Hydrologic Information Systems; Director, NEES Cyberinfrastructure Center; PI/Project Director, Geosciences Network; and member of the How Much Information? project.

Baru leads the Advanced Cyberinfrastructure Development Group at SDSC and is also Director of the Center for Large-scale Data Systems research. Prior to joining SDSC in 1996, Baru was at IBM, where he led one of the development teams for DB2 Parallel Edition Version 1 and at the University of Michigan, where he served on the faculty of the EECS Department. He received his B.Tech in Electronics Engineering from the Indian Institute of Technology, Madras, and M.E. and Ph.D. in Electrical Engineering from the University of Florida, Gainesville.

Engineering Notes on Homomorphic
Private Information Retrieval

Russ Fink
Johns Hopkins University Applied Physics Lab

11:15am-12:30pm, Friday, 4 December 4 2015, ITE 231

For two years, we have been investigating applications of private information retrieval (PIR) using the additive homomorphic scheme designed by Paillier that forms the basis of a space efficient PIR system by Ostrovsky, Skeith, and Bethencourt. We have implemented a working prototype and gained some insights about the technique, and identified improvements to make it practical to real-world privacy problems. I will present an overview of the technique, present a real world use case, and discuss our technical contributions and ongoing challenges.

Dr. Russ Fink is Chief Engineer of the Enterprise Security Group at APL. He earned the PhD from UMBC with a dissertation on applying trustworthy computing to voting.
