Yossi Oren

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.

My e-mail address is y|o|s|@e|n|g|.t|a|u|.a|c|.i|l|.
Here are the various social networks I have a profile on:

Other Academic Achievements

• News of our attack on the Israeli e-voting system is making the news - please check out Avishai's RFID page for the latest information.
• If you like security and cookies, perhaps you'd like to join us every Sunday at the Security Theater video seminar.
  
• Initial results regarding power analysis attacks against RFID tags were announced by Adi Shamir at the RSA Conference 2006. Here is the official web page describing these attacks.
• You can watch an online version of a talk about action recognition which I gave together with Moshe Blank at the Advanced Topics in Computer Vision course in 2005.
• You can also see the talk about Shannon's contributions to cryptography which I gave together with Gilad Tsur at Moni Naor's Key Papers in Computer Science course in 2006.

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.
