Sharma
Graduate Student
Electrical and Computer Engineering
Carnegie Mellon University
I
work with Anupam
Datta in the Department of ECE at Carnegie
Mellon University. I’m currently working on proving theoretical
guarantees about de-anonymization of records in
‘anonymized’ datasets, using mathematical
techniques to characterize properties that make re-identification of records
feasible. I’m also
working on defining accountability in protocols.
I
received my Bachelor’s degree (with Honors) in Electronics and Electrical
Communication at PEC University of Technology,
Chandigarh, India in May 2009.
As part of a six month research
internship (February-July 2008), I completed a semester thesis under the
guidance of Prof. Bernhard Plattner in Computer Engineering and Networks
Laboratory, D-ITET, ETH Zurich on 'Security of Field Based Routing' that
required securing the field based anycast routing
protocol for use in ad hoc networks. We proposed a novel taxonomy for
classifying the attacker classes and subsequent attacks which can be mounted on
the system. We also proposed two approaches for verification of the potential
values and integrated these with the other available mechanisms. Thesis report
is available here.
Previously, I have also completed a summer internship (June-July 2007) under
the guidance of Prof. Abhay
Karandikar in the Department of Electrical
Engineering at Indian Institute of Technology Bombay in the field of wireless
communication. We worked on 'Performance Evaluation of O-DRR scheduler in the
presence of TCP sources in WiMAX' that required simulating
the TCP sources in O-DRR multiclass environment. In this project, the O-DRR
scheduler performance was evaluated in presence of BE,
rtPS and nrtPS traffic, on
the basis of fairness in allocation of slots to TCP sources.
My current interests include data privacy, usability and computer security.
