Understanding online trade-offs

Parv Venkitasubramaniam, assistant professor of electrical and computer engineering, studies network security in hopes of protecting the identities of communicating parties and the paths along which data flow. He recently received a five-year CAREER Award from the National Science Foundation to support research into understanding the tradeoffs between utility and privacy. Venkitasubramaniam is particularly interested in protecting network users against adversaries who gain valuable information about users or networks based on the timing of data transmission.
