Meet Su Hyoung,

She is a Visual Arts major and current URA Scholar. Her research focuses on the Gwangju Art Biennale– a major exhibition of contemporary Asian art held every two years in South Korea..

Her research involved traveling to Korea and interviewing organizers of the Biennale. She also studied newspaper archives and private photo collections of families living in Gwangju.

This past weekend, Dr. Rick Forno, CYBR GPD and Assistant Director of the UMBC Center for Cybersecurity, joined Dr. Matt Blaze (UPenn), Dr. Jeff Foster (UMCP), and COL (Ph.D) Greg Conti (USMA) on the closing plenary panel for Schmoocon 2016 in Washington, DC.

ShmooCon is an annual east coast hacker convention offering three days of an interesting atmosphere for demonstrating technology exploitation, inventive software and hardware solutions, and open discussions of critical infosec issues.  The first day is a single track of speed talks called One Track Mind.  The next two days bring three tracks:  Build It, Belay It, and Bring It On.

The panel examined the current state of information security programs in academia. Along the way they discussed issues around dealing with administration and the peculiarities of information security, the current state of information security research, attracting and vetting students/faculty, and generally what it’s like to be growing the next generation of information security professionals in a time where academia frequently is placed in the position of “building the bus while going down the road.”

cMix: Anonymization by High-Performance Scalable Mixing

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.
