Boaz Tsaban was born in 1973 in Or Yehuda

Boaz Tsaban was born on February 6, 1973, in Or Yehuda, a city near Tel Aviv. His parents were born in Libya. He attended Kfar Kaufman high school in Or Yehuda.

At 16 he joined the first cycle of a special mathematics program for high school students at Bar-Ilan University. A year later he began regular university courses in mathematics. He earned his B.Sc., M.Sc. and Ph.D. at Bar-Ilan, with a doctorate supervised by Hillel Furstenberg.

He spent 2 years as a postdoctoral fellow at the Hebrew University and 3 years as a Koshland Fellow at the Weizmann Institute of Science. In 2007 he joined the Department of Mathematics at Bar-Ilan University.

In selection principles he developed the method of omission of intervals for proving covering properties of sets of real numbers. In cryptology he developed the algebraic span method, which solved computational problems behind several proposed nonabelian public-key schemes. He won the Nessyahu Prize in 2003 and the Krill Prize in 2009.
