Shalom and welcome!

My name is Yossi Oren.  I'm currently a Ph.D. student at  the Cryptography and Network 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.

Non-academic Achievements

My primary non-academic achievements are my incredible kids Yair, Renana and Dvir. 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.
