|Welcome to my homepage!
I joined the Computer Science department at Brown University in Fall 2002, after finishing my PhD thesis at MIT.
My research area is cryptography. On of the main thrusts of my research is on practical cryptographic tools for privacy-preserving transactions. A typical computer user performs a multitude of electronic transactions each day: reading e-mail, managing bank accounts, making on-line purchases, to name a few. Each of them must be secure: they should be carried out by authorized users only, and the information entered must be authentic. On the other hand, each transaction should be private: personal information or account balances should not become available without a user's explicit consent. It is highly desirable to limit the information transmitted in each transaction to a bare minimum without compromising its authenticity. In particular, since data aggregation is simple to do, there should be no information revealed that can link a transaction to another transaction carried out by the same individual.
