The emergence of environments where computing devices are embedded pervasively in the physical world has made possible many interesting applications and triggered several new research areas. Mobile ad hoc networks (MANETs), sensor networks, and RFID systems are all examples of such pervasive systems. Operating on an open medium with constrained resources, such networks suffer from specific security vulnerabilities. Traditional security approaches, in particular regarding provision of availability, are often inappropriate for the context of ubiquitous computing.
This presentation investigates the security of RFID systems
with focus on availability and privacy issues in the presence of
Byzantine adversaries.
We formulate rigorous simulation frameworks for analyzing
security objectives and design novel mechanisms
and algorithms that achieve proven availability, efficiency,
authenticity, and privacy for RFID applications.

I joined the faculty of the Computer Science Department
at Florida State University after completing a Ph.D. degree
in Computer Science from The Johns Hopkins University (2004).
My published research includes works on privacy-preserving
protocols, group signatures schemes,
identity-based cryptographic primitives, and applications.
Some of my current research interests are
in the areas of elliptic-curve cryptography,
provably secure ubiquitous systems, and
privacy-enhanced protocols and services.
