With developments in quantum computers and algorithms, the public-key systems that we rely upon for secure network communication will become vulnerable to exploitation. Quantum-resistant key exchange protocols are needed to replace our existing vulnerable protocols. Much of the work has focused on developing new mathematical problems that are conjectured to be quantum-resistant as replacements for our current public-key algorithms. We took a different approach, looking to an old secret-key agreement protocol developed by Leighton and Micali at MIT for the Clipper Chip symmetric encryption system. We will present our analysis of the Leighton-Micali key agreement protocol, weaknesses we uncovered with the Cryptographic Protocol Shapes Analyzer (CPSA), and verification of a new protocol based on their ideas that corrects deficiencies in the original protocol.

talk: Formal Methods Analysis of the Session Binding Proxy Protocol, 12-1 Fri 4/1
The UMBC Cyber Defense Lab presents
A Formal Methods Analysis of the Session Binding Proxy Protocol
Proposed by Burgers, Verdult, and Eekelen in 2013, the Session Binding Proxy (SBP) protocol intends to prevent session hijacking by binding the application session to the underlying network session (i.e., binding the session token to the SSL/TLS shared key). We present a formal methods analysis of SBP using the Cryptographic Protocol Shapes Analyzer (CPSA). Our analysis reveals that SBP relies critically on the successful establishment of a secure SSL/TLS channel, which can be undermined using well-known attacks. Also, we find that SBP allows for the partial hijacking of a session using a tailgating attack. In this attack, the adversary uses the server to inject and execute malicious code inside the client’s browser to extract the session token and forge a valid state-changing request to the server. This attack is not neutralized by SBP because the request contains a valid session token and is sent over the client’s existing SSL/TLS channel.

Prof. Matuszek receives prestigious NSF CAREER award for robotics research
Prof. Cynthia Matuszek receives prestigious NSF CAREER award for robotics research
CSEE professor Cynthia Matuszek received an NSFCAREER award to support her research on improving the ability of robots to interact with people in everyday environments. The five-year award will provide nearly $550,000 in funds to support research by Dr. Matuszek and her students in the Interactive Robotics and Language lab.
The CAREER award is part of the NSF Faculty Early Career Development Program and is considered one of NSF’s most prestigious grants. It supports faculty members beginning their independent careers and who have “the potential to serve as academic role models in research and education and to lead advances in the mission of their department or organization.” One of the program’s central goals is to help early-career faculty “build a firm foundation for a lifetime of leadership in integrating education and research.”
Dr. Matuszek joined UMBC in 2014 after receiving her Ph.D. at the University of Washington in Seattle, where she was co-advised by Dieter Fox and Luke Zettlemoyer. Before beginning her graduate studies, she was a senior research lead at Cycorp.
Dr. Matuszek’s proposal, Robots, Speech, and Learning in Inclusive Human Spaces, addresses the problem of how robots can use spoken language and perception to learn how to help support people. A description of her project is below.
“The goal of this project is to allow robots to learn to understand spoken instructions and information about the world directly from speech with end users. Modern robots are small and capable, but not adaptable enough to perform the variety of tasks people may require. Meanwhile, too many machine learning systems work poorly for people from under-represented groups. The research will use physical, real-world context to enable learning directly from speech, including constructing a data set that is large, realistic, and inclusive of speakers from diverse backgrounds.
As robots become more capable and ubiquitous, they are increasingly moving into traditionally human-centric environments such as health care, education, and eldercare. As robots engage in tasks as diverse as helping with household work, deploying medication, and tutoring students, it becomes increasingly critical for them to interact naturally with the people around them. Key to this progress is the development of robots that acquire an understanding of goals and objects from natural communications with a diverse set of end-users. One way to address this is using language to build systems that learn from people they are interacting with. Algorithms and systems developed in this project will allow robots to learn about the world around them from linguistic interactions. This research will focus on understanding spoken language about the physical world from diverse groups of people, resulting in systems that are more able to robustly handle a wide variety of real-world interactions. Ultimately, the project will increase the usability and fairness of robots deployed in human spaces.
This CAREER project will study how robots can learn about noisy, unpredictable human environments from spoken language combined with perception, using context derived from sensors to constrain the learning problem. Grounded language refers to language that occurs in and refers to the physical world in which robots operate. Human interactions are fundamentally contextual: when learning about the world, we focus on learning by considering not only direct communication but also the context of that interaction. This work will focus on learning semantics directly from perceptual inputs combined with speech from diverse sources. The goal is to develop learning infrastructure, algorithms, and approaches to enable robots to learn to understand task instructions and object descriptions from spoken communication with end users. The project will develop new methods of efficiently learning from multi-modal data inputs, with the ultimate goal of enabling robots to efficiently and naturally learn about their world and the tasks they should perform.”

talk: Ted Selker on Voting Technology, 12-1, Fri 3/4
Traditionally most votes are lost in registration, voting ballot design problems, and polling place operations, causing long lines and possibly mail-in ballot fraud. This talk will describe voting-process problems and technological problems, and some possible solutions for voting improvement. Voting disenfranchisement is much higher for people with perceptual, physical, and cognitive disabilities. More than 14% of registered voters are in danger of increased errors due to dyslexia, and more than 6.5% due to short-term memory problems. We will describe and demonstrate technologies we are making that help disabled people and improve voting universally as well.
Dr. Ted Selker is an entrepreneur inventor who also mentors innovation. Ted spent five years as director of Considerate Systems research at Carnegie Mellon University Silicon Valley and in developing the campus’s research mission. Prior to that, Ted spent ten years as an associate professor at the MIT Media Laboratory, where he created the Context Aware Computing group, co-directed the Caltech/MIT Voting Technology Project, and directed the Industrial Design Intelligence future for product design project. Prior to that, his successes at targeted product creation and enhancement at IBM earned him the role of IBM Fellow. Ted’s work birthed successful products ranging from notebook computers to operating systems. It accumulated numerous awards, patents, and papers and has often been featured in the press. Ted is co-recipient of the Computer Science Policy Leader Award for Scientific American 50, the American Association for People with Disabilities Thomas Paine Award for his work on voting technology, and the Telluride Tech Fest Award.

Meet UMBC’s alumni who built the Smithsonian’s Searchable Museum, expanding online access to African American history and culture
TheNational Museum of African American History and Culture (NMAAHC) is known for its stunning architecture and powerful, immersive exhibits. More than 600,000 visitors experienced the NMAAHC – the newest Smithsonian museum – in the first three months of its opening in Washington, D.C. During the COVID pandemic, the museum wondered how it could best reach audiences unable to visit in person. Enter Baltimore-based tech company Fearless and a team of UMBC alumni bridging computing and the arts.
Fearless, founded by Delali Dzirasa ‘04, computer engineering, led the development of the Searchable Museum to complement the NMAAHC’s “Slavery and Freedom” exhibition. The Fearless and NMAAHC teams worked together to reimagine this exhibit specifically for online audiences.
The Smithsonian’s announcement of the new platform notes, “Over a year in the making, the Searchable Museum initiative is one of the museum’s largest digital undertakings, bringing the museum’s evocative content and immersive in-person visitor experience into homes around the world.”
