We work on fundamental as well as practical aspects of security and privacy. In the area of security, we work in authorization logics and access control models, designing secure systems, and cryptographic protocols. In the area of privacy we work on designing practical privacy preserving advertisement systems, formally defining notions of privacy, as well as in designing algorithms that simultaneously provide functional value and guarantee privacy.

Active ongoing projects:

• Authorization and Access Control
• Access control for databases
• FPGA Hardware assisted security
• Noiseless Privacy
• Privacy preserving learning
• Privacy preserving mining
• Privacy preserving advertising
