Shalom and welcome!

My name is Yossi Oren.  I'm currently a Ph.D. student at  the Computer Network and Security Lab at Tel-Aviv University, led by Prof. Avishai Wool.  My research interests are:

  • Secure Hardware: Power analysis and other hardware attacks and countermeasures on cryptographic devices; Low-resource cryptographic constructions for lightweight computers such as RFID tags.
  • Cryptography in the real world: Consumer and voter privacy in the digital era; Web application security

I was previously an M.Sc. Student in the Department of Computer Science and Applied Math of the Weizmann Institute of Science, where my thesis advisor was Prof. Adi Shamir.  My work is currently sponsored by a research fellowship from the Check Point Institute for Information Security.

Non-academic Achievements

My primary non-academic achievements are my incredible kids Yair and Renana. Here are some pictures of us:


My employer for the last 9 years, Proxy Software Systems, went bankrupt in late 2008.  I put up a little tribute page.
