Northeastern University professor Cristina Nita-Rotaru has been researching how to keep information both accessible and safe for 17 years.
Nita-Rotaru says her work focuses on balancing the ying and yang of the networked world. She designs collections of computers that can work together to achieve a goal while withstanding compromise--they must work despite misconfigurations and malicious attacks.
When teaching security, Nita-Rotaru and colleagues tell students a computer does no one any good if it is locked in a safe. "To be useful, computers must interact with each other through network protocols, which opens the door for attacks," she says.
Nita-Rotaru recently worked with other researchers to analyze the security and performance capabilities of Google's new QUIC (Quick UDP Internet Connections) networking protocol, which is part of the Chrome browser. She also oversaw the development of technology called the State-based Network AttacK Explorer (SNAKE), which automatically targets attacks that could sabotage conversations between computers.
