Shalom and welcome!
My name is Yossi Oren. I‘m currently a Post-Doctoral Research Scholar in the Department of Computer Science at Columbia University in the City of New York. I am a member of the Network Security Lab, led by Prof. Angelos Keromytis, and the Computer Architecture and Security Technology Lab, led by Prof. Simha Sethumadhavan. 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 a Ph.D. student at the Cryptography and Network Security Lab at Tel-Aviv University, led by Prof. Avishai Wool, and 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|@c|s|.c|o|l|u|m|b|i|a|.e|d|u.

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
- 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.
My primary non-academic achievements are my incredible kids Yair, Renana, Dvir and Talia Bat-Zion.
My employer for 9 years, Proxy Software Systems, went
bankrupt in late 2008. I put up a little tribute page.
