About

My research and work is influenced by my moral beliefs. They are based on the Cypherpunk's Manifesto (Eric Hughes, 1993) and modern critiques of our research field, such as The Moral Character of Cryptographic Work (Phillip Rogaway, 2015):

“Cryptography rearranges power: it configures who can do what, from what. This makes cryptography an inherently political tool, and it confers on the field an intrinsically moral dimension.

The Snowden revelations motivate a reassessment of the political and moral positioning of cryptography. They lead one to ask if our inability to effectively address mass surveillance constitutes a failure of our field.

I believe that it does. I call for a community-wide effort to develop more effective means to resist mass surveillance. I plead for a reinvention of our disciplinary culture to attend not only to puzzles and math, but, also, to the societal implications of our work.”

Research

My research interests focus on these topics:

  • Contextual Security for Device-to-Device Pairings based on Human Gait, Ambient Audio
  • End-to-End Encrypted Communication: API for NFC Cryptography, ZRTP Analysis, Usability of Key-Fingerprints
  • Security in Delay-Tolerant Networks: Forward Secure DTNs, µDTNSec, RAIM: Redundant Array of Motes
  • Trustworthy Transportation Systems: Cooperative Charging, Trustworthy Parking Communities

I published over 15 papers on international conferences and journals.
