Shalom and welcome!

My name is Yossi Oren.  I‘m a Senior Lecturer (Assistant Professor in U.S. terms) in the Department of Software and Information Systems Engineering in Ben-Gurion University. I am also a member of BGU's Cyber Security Research Center. 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

My research lab (and how to join it!)

Here are the various social networks I have a profile on:

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

Yossi Oren's Family

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