Research


Being interested in all aspects of computer and communication security, I am currently focussing on cloud computing security and privacy. I am investigating new protocols for outsourcing storage and computation to public clouds. My goal is to design protocols that assure security and privacy in case of an untrusted cloud provider. I consider my research as "use-inspired": I target protocols that do not only have a solid theoretical foundation, but are practical and efficient in real-world clouds today.



Short Bio


Before joining Northeastern, as a postdoc and senior researcher at EURECOM, France, I have researched security and privacy for RFID systems. More specifically, I have designed new protocols for authentication, payment, and anti-counterfeiting. Even before, I researched wireless sensor networks and designed protocols for key exchange and secure data aggregation. I hold a Diploma and a PhD (with distinction) in computer science from Universität Karlsruhe in Germany. My thesis was awarded with the prize for the best security research thesis by Germany's “data security organization (GDD)” in 2007.


Projects


I am Principal Investigator of “Privacy and Security for MapReduce Clouds with PASMAC”

funded by NSF grant CNS—1218197. Research has started September 1st 2012, find the project’s homepage here.

My research has also been supported by a grant from VISA.


Teaching

In fall 2012, I have taught CS 6750, “Cryptography and Communications Security”. Find its homepage here.
