UMBC’s Naghmeh Karimi receives NSF CAREER Award to develop long-lasting security for cryptographic chips

 

Naghmeh Karimi receives NSF CAREER award to develop long-lasting security for cryptographic chips

 

Naghmeh Karimi is the most recent UMBC faculty member to receive a prestigious CAREER Award from the National Science Foundation (NSF). The grant, totaling approximately $500,000 over five years, will support her work to investigate how device-aging related risks compromise the security of cryptographic devices.

Karimi explains that cryptographic chips offer continued advances in authenticating messages and devices as well as preserving the integrity and confidentiality of sensitive information. They do so by implementing cryptographic algorithms in hardware. These chips combine the benefits of cryptographic applications with the speed and power advantage of hardware implementations. 

Despite their significant benefits, cryptographic chips can be compromised by adversaries who have gained physical access to the chips. Current protections against such attacks do not consider the aging of devices, which can shift device parameters over time.

Addressing security vulnerabilities 

Aging makes cryptographic chips operate slower and, ultimately, results in their malfunction, says Karimi. She explains that the typical lifetime of integrated circuits is 7 to 8 years. As the devices age, their performance decreases. Karimi is exploring the specific security vulnerabilities of aged devices and how they can be protected.

“We want to preserve the security of devices over their lifetime,” Karimi says.

Karimi and her research team will study whether the success of the side-channel analysis and fault-injection attacks increase in older devices. Karimi will create and test several countermeasures to protect devices against such attacks.

Connecting students with opportunities in tech security

The CAREER Award funding will support several UMBC undergraduate and graduate student researchers working with Karimi to develop long-lasting security solutions for hardware platforms. 

At the same time, Karimi will also develop and launch a new course in UMBC’s computer science and electrical engineering department on cryptography, hardware security, and testing. She will also work with the UMBC Cyber Scholars Program to connect students with internship opportunities focused on hardware security, to give them additional hands-on experience in the field. 

“The success of this project will enable us to develop long-lasting security for trusted hardware platforms,” Karimi says. “This will result in aging-resistant security solutions that benefit society through devices that remain secure over their lifetime.”

Investigating the Impact of Device Aging on the Security of Cryptographic Chips

 

Professor Naghmeh Karimi received a prestigious NSF CAREER award to support her research on Investigating the impact of device aging on the security of cryptographic chips.

CAREER awards are among NFS’s most prestigious awards and are intended to support early-career faculty 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.

Cryptographic chips implement cryptographic functions in hardware for better performance. Despite the significant performance benefits, cryptographic chips can be compromised by the adversaries via monitoring their power-consumption, tampering their logic or placing the chips under stress to generate erroneous outputs to infer sensitive data. The current protections against such attacks do not consider the aging of the devices that can cause a parametric shift of device parameters over time which can compromise device security.

Supported by this five-year award, Professor Karimi and her students will investigate the effects of device aging on the security of cryptographic devices, particularly those with protection against physical attacks, and develop solutions to ensure security when device aging comes into account. Her work will help enable the development of long-lasting security for trusted hardware platforms, and result in aging-resistant security solutions that benefit the society via devices that remain secure over their lifetime.

UMBC faculty poised to help shape national policies in computing

UMBC faculty poised to help shape national policies in computing

Adam Bargteil, assistant professor of computer science and electrical engineering, has been named chair-elect of the Association for Computing Machinery’s (ACM) Special Interest Group on Computer Graphics and Interactive Techniques (SIGGRAPH). He will lead SIGGRAPH as chair starting Fall 2020.

With Bargteil’s election, UMBC’s College of Engineering and Information Technology (COEIT) now has two faculty members serving as leaders of two of the ACM’s largest special interest groups. Helena Mentis, associate dean for academic programs and learning in COEIT and associate professor of information systems, has been president of the Special Interest Group on Computer-Human Interaction (SIGCHI) since July 2018.

In these leadership roles, Bargteil and Mentis will have an opportunity to shape important policy matters, including redesigning computing education guidelines.

Bargteil’s group, SIGGRAPH, is the leading international society for computing professionals and students in computer graphics and interactive techniques, attracting people from academia, industry, and artistic communities. Bargteil helped create the ACM SIGGRAPH Frontiers program, which highlights emerging fields of research, such as machine learning, medical applications of computer graphics, and autonomous vehicles.

Bargteil plans to continue to empower the SIGGRAPH executive committee to create high-impact programming and opportunities for conversation among members when he is at the helm next year. “I’d like to continue to be proactive, and create more value for the members of SIGGRAPH,” he shares.

Over the summer, Bargteil participated in an intensive leadership program, which he says helped him prepare for his upcoming role in SIGGRAPH. Reflecting on the experience, Bargteil says that he found the selected readings, training exercises in public speaking, and opportunities to connect closely with fellow participants to be valuable for his growth as an emerging leader in computing.

SIGCHI, the group Mentis leads, is the world’s largest association for professionals in human-computer interaction. The group’s main conference attracts more than 3,500 attendees each year, and the SIG sponsors 23 specialized conferences.

Mentis is director of UMBC’s Bodies in Motion Lab, and focuses on how technologies can improve collaboration and coordination in healthcare contexts, from empowering patients to helping surgeons utilize interactive imaging. SIGCHI is a highly multi-disciplinary community that includes researchers and students in fields from sociology to mechanical engineering.

Dr. Forno discusses the Baltimore Ransomware attack on Maryland Public TV program

Maryland Public Television’s Charles Robinson reports on how Baltimore continues to recover after city computers were infected with ransomware in the May 2019 Baltimore ransomware attack and interviews Dr. Rick Forno, associate director of the UMBC Center for Cybersecurity and graduate director of UMBC’s Cybersecurity MPS degree program.

From Wikipedia: On May 7th 2019, most of Baltimore’s government computer systems were infected with a new and aggressive ransomware variant named RobbinHood. All servers, with the exception of essential services, were taken offline. In a ransom note, hackers demanded 13 bitcoin (roughly $76,280) in exchange for keys to restore access. The note also stated that if the demands were not met within four days, the price would increase and within ten days the city would permanently lose all of the data.

As of May 13, 2019 all systems remained down for city employees. It is estimated that it will take weeks to recover. According to Mayor Jack Young, US Federal Law enforcement continue to investigate the attack. The attack had a negative impact on the real estate market as property transfers could not be completed until the system was restored on May 20th. However, the restoration of all systems was, as of May 20, 2019, estimated to take weeks more.

Baltimore was susceptible to such an attack due to its IT practices, which included decentralized control of its technology budget and a failure to allocate money its information security manager wanted to fund cyberattack insurance. The attack has been compared to a previous ransomware attack on Atlanta the previous year, and was the second major use of the RobbinHood ransomware on an American city in 2019, as Greenville, North Carolina was also impacted in April.

New NSF award will help robots learn to understand humans in complex environments

New NSF project will help robots learn to understand humans in complex environments

UMBC Assistant Professor Cynthia Matuszek is the PI on a new NSF research award, EAGER: Learning Language in Simulation for Real Robot Interaction, with CO-PIs Don Engel and Frank Ferraro. Research funded by this award will be focused on developing better human-robot interactions using machine learning to enable robots to learn the meaning of human commands and questions informed by their physical context.

While robots are rapidly becoming more capable and ubiquitous, their utility is still severely limited by the inability of regular users to customize their behaviors. This EArly Grant for Exploratory Research (EAGER) will explore how examples of language, gaze, and other communications can be collected from a virtual interaction with a robot in order to learn how robots can interact better with end users. Current robots’ difficulty of use and inflexibility are major factors preventing them from being more broadly available to populations that might benefit, such as aging-in-place seniors. One promising solution is to let users control and teach robots with natural language, an intuitive and comfortable mechanism. This has led to active research in the area of grounded language acquisition: learning language that refers to and is informed by the physical world. Given the complexity of robotic systems, there is growing interest in approaches that take advantage of the latest in virtual reality technology, which can lower the barrier of entry to this research.

This EAGER project develops infrastructure that will lay the necessary groundwork for applying simulation-to-reality approaches to natural language interactions with robots. This project aims to bootstrap robots’ learning to understand language, using a combination of data collected in a high-fidelity virtual reality environment with simulated robots and real-world testing on physical robots. A person will interact with simulated robots in virtual reality, and his or her actions and language will be recorded. By integrating with existing robotics technology, this project will model the connection between the language people use and the robot’s perceptions and actions. Natural language descriptions of what is happening in simulation will be obtained and used to train a joint model of language and simulated percepts as a way to learn grounded language. The effectiveness of the framework and algorithms will be measured on automatic prediction/generation tasks and transferability of learned models to a real, physical robot. This work will serve as a proof of concept for the value of combining robotics simulation with human interaction, as well as providing interested researchers with resources to bootstrap their own work.

Dr. Matuszek’s Interactive Robotics and Language lab is developing robots that everyday people can talk to, telling them to do tasks or about the world around them. Their approach to learning to understand language in the physical space that people and robots occupy is called grounded language acquisition and is a key to building robots that can perform tasks in noisy, real-world environments, instead of being pre-emptively programmed to handle a fixed set of predetermined tasks.

Tim Finin named ACM fellow for contributions to knowledge sharing

Prof. Tim Finin named ACM Fellow for contributions to knowledge sharing

UMBC’s Tim Finin, professor of computer science and electrical engineering (CSEE), has been named a fellow of the Association for Computing Machinery (ACM), a distinctive honor granted to less than one percent of all ACM members. ACM fellows are selected based on their work to advance computing over the course of a career, in areas such as mobile networks, computer architecture, robotics, and security.  Finin was cited for his  “contributions to the theory and practice of knowledge sharing in distributed systems and the World Wide Web.”

“It’s a great honor to be selected as an ACM fellow, since it is based on the recommendations of one’s peers and recognizes contributions to the field of computing,” says Finin. “I am especially honored since ACM fellows include so many pioneers of the field whose work and contributions I have studied and used over the past 40 years.”

“Dr. Finin has been a leader in our department ever since he came in as the chair in 1991,” says Anupam Joshi, professor and chair of CSEE. “He is one of our most accomplished researchers, and in addition to this fellowship, has been recognized both internally (as a Presidential Research Professor) and externally with numerous awards.”

Joshi continues, “Tim is a great teacher, and he has mentored a number of our mid-career and senior faculty, including me!”

Throughout his career, Finin has been involved with various aspects of ACM. As a graduate student at the University of Illinois Urbana-Champaign, Finin became a member of ACM’s special interest group on artificial intelligence (SIGART), which is one of his primary areas of focus. In the years since then, he has collaborated with numerous many UMBC faculty, students, and alumni, in addition to colleagues in industry and at other institutions, to move this work forward.

In the 1990s, and with support from the Defense Advanced Research Projects Agency (DARPA), Finin worked with UMBC faculty to develop new software standards to support the then-new concept of intelligent multiagent systems. The software, called the Knowledge Query and Manipulation Language, was used to develop intelligent applications and as the basis for faculty research and many Ph.D. dissertations.

The ACM’s Conference for Information and Knowledge Management awarded Finin and his collaborators with the 2018 Test of Time Award for a 1994 paper about this research that has continued to have an important impact on the research community.

Finin and a group of collaborators also worked on projects related building the semantic web. “The idea was to enhance the new web technologies with a way to enclose structured data that machines could use into ordinary web pages,” he explained. He adds that this allowed computers to understand the information on the web page without having to understand natural language.

Starting in the 2000s, Finin and his collaborators focused much of their work on blogs and then social media, including Facebook and Twitter. They explored how to analyze the data collected on these sites, and also how to protect and improve security and privacy features.

“I’ve only been able to do this because of the environment at UMBC,” Finin says, reflecting on the encouragement he has received to pursue new collaborations and areas of research.

“Based on my experience,” he shares, “I hope to mentor more faculty in the middle of their careers,” to help them access opportunities through organizations like ACM.

Finin currently oversees and mentors UMBC’s student chapter of ACM, which includes both undergraduate and graduate students. The student organization sponsors weekly talks and other events for people in the UMBC community who are interested in computing and related topics.

Finin joins Roy Rada, professor emeritus of information systems, who is also an ACM fellow.
