The 10th BIU Winter School on Cryptography

Information Theoretic Cryptography

February 17-20, 2020

School Overview

Information-theoretic cryptography aims at achieving security in the presence of computationally unbounded adversaries. This area covers a wide array of topics at the intersection of cryptography, coding theory, information-theory and theory of computation. Information-theoretic protocols provide unconditional security that is not based on unproven computational intractability assumptions, whereas information-theoretic lower-bounds reveal the inherent limitations on the achievability of unconditional security. In addition, information-theoretic methods and reductions lie at the heart of many computational constructions.

In the 10th BIU Winter School on Cryptography, we will study the theory of information-theoretic cryptography. The program will cover the following topics:
private-information retrieval, secret sharing and conditional disclosure of secrets, consensus, and secure multiparty protocols.

The winter school program is designed to teach the topic from its basics up to the latest research. The target audience for the school is graduate students and postdocs in cryptography (we will assume that participants have taken at least one university-level course in cryptography). However, all faculty, undergrads and professionals with the necessary background are welcome. The winter school is open to participants from all over the world; all talks will be in English.

Additional Information

Organizers: Benny Applebaum, The School of Electrical Engineering, Tel Aviv University, Carmit Hazay, Faculty of Engineering, Bar-Ilan University and Benny Pinkas , Department of Computer Science,  Bar-Ilan University, Israel.

Where: The winter school will take place at the Rayman hall at Kfar Hamaccabiah events & conference center in Ramat Gan

When: Monday, February 17, 2020 to Thursday, February 20, 2020

Registration: Registration is 750 shekels for the entire school. Registration is free for overseas participants (due to costs already incurred due to travel). Israeli participants who have difficulty paying the registration fee can request a waiver; please include this in the special request box in the registration form. After registration has been confirmed, Israeli participants will receive a link to carry out the payment. Registration will be considered complete only after payment.

Registration includes school participation, lunch, refreshments and the excursion (accommodation is not included).

Registration is available here. Please register by January 20, 2020.

Contact: For any questions or queries, please send an e-mail to: winterschool.biu@gmail.com

Hotel: We have arranged a special rate at the Kfar Hamaccabiah Hotel where the conference center is located. The rate is $180 a night for a single room, $200 a night for a double room (with two occupants) and $240 for a triple room (with three occupants). The rate includes breakfast. Hotel reservation form will be available soon.

Sponsorship: This winter school is graciously sponsored by the BIU Center for Research in Applied Cryptography and Cyber Security in conjunction with the Israel National Cyber Bureau in the Prime Minister’s Office and Bar-Ilan University.
