CS Talk: Robert Lychev

Is the juice worth the Squeeze? Evaluating S*BGP Security Benefits in Full and Partial Deployment: I am currently a PhD student at Georgia Institute of Technology at the College of Computing, working with Alexandra Boldyreva and Nick Feamster. I am primarily interested in applying cryptographic and game theoretic concepts to problems of security and incentives in routing and accountability. In the recent past I was working with Yevgeniy Vorobechik at Sandia National Laboratories Livermore, California as a summer intern. Before that, for two years I was a visiting researcher at Boston University Security Group working with Sharon Goldberg. Before joining Georgia Tech I obtained bachelors and masters degrees at University of Massachusetts Amherst, where I was advised by Kevin Fu.
